Time is a critical element of our existence that will never get old, and with technology, we can find better and more intuitive ways to measure it. In one of our past tutorials, we looked at how the DS3231 real time clock module can be used with Arduino to display time on a 16×2 LCD display. Today, we will build an upgrade to that project using an Arduino Due, the DS3231 RTC module and a 3.2″colour TFT display in place of the 16×2 LCD display used in the previous project.
At the heart of today’s project is the DS3231 real time clock module which we will use to obtain the current time, date and temperature of the environment. The DS3231 real time clock module is one of the most popular real-time clock chips among makers and DIY enthusiasts. It is a low-cost, highly accurate, I2Cbased real-time clock (RTC) with a temperature-compensated crystal oscillator (TCXO) and crystal integrated into it. The module integrates a coin cell battery input which helps it retain date and time even when the main power to the device is interrupted. It maintains seconds, minutes, hours, day, date, month, and year information, automatically adjusting the date for months with fewer than 31 days, including corrections for leap year. It can be set to operate either in the 24-hour or 12-hour format with an active-low AM/PM indicator. It has been used in several projects on this website mostly, due to its accuracy, and its low power requirements which help it keep time accurately, for a longer period of time compared to other real-time clocks (RTC) modules.
Another key part/component that we will use in today’s tutorial is the Arduino Due. One of the important things, when designing electronic systems that have displays is ensuring, that there is no flicker or lag when updating information on the screen and one of the best ways to ensure that, is to use a fast enough micro-controller. Putting this into consideration, for this project, we will use the very fast Arduino Due board. The Arduino Due has one of the fastest CPU in the Arduino family. The Due runs on an 84MHz CPU compared to the 16MHz CPU speed of the Arduino UNO, and as such, it is able to update the screen without any visible flickering.
The most important update to the previous project, however, is the 3.2″color LCD display being used. The display gives us the ability to create a better, bigger and colourful user interface for our clock at a cheap price as it costs about 7$ on banggood.
The goal for this project is to build a real-time clock with a user-friendly interface capable of displaying (without lag or flickering) the current time, date, temperature including the minimum and maximum temperature recorded in a particular environment over time.
The 3.2″ TFT, like most other TFT displays, comes as a shield which can be easily mounted on the Arduino Due. This, however, makes it difficult to access the IOs of the Arduino after the display has been mounted, as it tends to cover the front face of the board. To solve this, so that the DS3231 module can be connected, male headers are used (after bending them as shown in the picture below) to connect the RTC module to the Arduino.
To easily write the code for this project, we will use two libraries: the Bodmer TFT HX8537 library for the TFT display and the Sodaq DS3231 library to easily interface with the DS3231 module. Both libraries can be downloaded via the links attached to their names above. The Bodmer library is a version of the UTFT library specially modified for the Arduino Due as this particular display is incompatible with the UTFT library.
Next is the void setup function. We initiate communication with the RTC module and Initialize the display, setting our preferred orientation for the display and print the UI to the display.
With this done, we move to the void loop function. Under this function, we write the code to update all the parameters (after specific intervals) on the display including the min temperature, the max temperature, time and the date.
That’s it for this tutorial guys, there are several useful projects that can be built using this tutorial as a foundation. You could decide to add a buzzer to the project to create an alarm clock or make a to-do list based project, all out of this.
When you are using DS1302, DS1307 or DS3231 RTC in your real time clock project, You may have observed it’s library works on 24 hours format clock. If you are like me who don’t like to see clock in 24 hour format, this tutorial is for you. we will learn how to set 12 hour clock in RTC (Real Time Clock) using DS1302 with TFT Display. It is simple to convert from 24 hour format to 12 hour format clock by using any of DS1302, DS1307 or DS3231 RTC. In short we are subtracting 12 hours from 24 hours. So let’s get started.
Download library for Real Time Clock library from Rinky-Dink Electronics OR you can download it from here because library may change by the time or it may not work.
The latest Chinese TFT displays are quite low in price but work perfectly with Arduino and Raspberry Pi. There are two different types of TFT shields available: one with 26 pins (13×2 DIL) for Raspberry Pi and the other as Arduino TFT shield for Arduino Uno board.
Arduino TFT shield can be perfectly mounted on top of an Arduino Uno board. But a major disadvantage is that after mounting the shield on Arduino Uno board, it is difficult to use its GPIO pins for any other application.
The Arduino TFT shield has a micro SD card attached that gets connected to its serial peripheral interface (SPI) pins for communication with the microcontroller. This micro SD card is not used in this project.
The main hurdle with this display is that it is not common and is available only from mcufriend.com. Fortunately, the mcufriend_kbd.h header file is freely available and it works out of the box for this and many other similar displays. The other header file required for this display is Adafruit_GFX.h. Both these header files, along with the main source code, are given below.
This project creates an analogue dial clock along with digital date, time and temperature display using an LM35/TMP36 temperature sensor. The time signal is derived from a U-Blox NEO-6M GPS receiver module. Once the technique is understood, it can be deployed for many other applications.
The connections are easy to make as shown in Fig. 2. The pin connections of the Arduino TFT shield are straightforward; you just need to mount the shield on top of the Arduino Uno board. The pin-to-pin connection details between TFT shield and Arduino Uno are given in the table.
Since top portion of the Arduino Uno is covered by TFT shield, the connections for the TMP36 and GPS receiver are taken from the bottom side of the Arduino Uno board (refer Fig. 3). In case you want to free some Arduino pins then you should see the mcufriend_shield.h file and re-write the connections to do so.
Writing the Arduino code/sketch (GPS_analog_clock.ino) for the project is real fun! You can make TFT display in many different ways through coding. Creating a thick border line, making the hour and minutes hands move smoothly were quite challenging as Adafruit_GFX library is not so much developed. High school trigonometry is all that you need to make it happen for you.
After uploading the code, solder the pins of TMP36 and GPS module to the Arduino board. Then mount the TFT shield on top of the Arduino board. After all the connections are done as per Fig. 2, connect it to 3.3V DC source. GPS module requires a few minutes to trace the satellites.
Most GPS receivers have an inbuilt patch antenna that can locate the low Earth orbit (LEO) GPS satellites very easily, even if your room’s windows are closed. As soon as two such satellites are located, the time starts appearing on the analogue dial. At the same time, the date, time and temperature are shown digitally on right side of the TFT display.
Clock is my fascination. I have made clocks of several variety & themes but I never made any clock which have millisecond display. The reason being the huge load of processing power which always falls short for the demand of fast changing display.
However, the first success came when I successfully could run the 3.5” ILI9488 TFT display on 8 bit mode with ESP32. On 8 bit mode it needs 12 GPIO pins to run the display and it is really very fast and there lies the success of this millisecond display clock.
Although the TFT display fits very easily on an Arduino UNO but this millisecond display is not possible on Arduino UNO as it lacks the computing power.
The time is calculated from the RTC DS3231. This RTC have capability of measuring temperature as well which is also displayed on the TFT. The time duration between consecutive seconds is divided by 1000 to calculate the millisecond and displayed on the TFT. The simple line drawing is tricked to created thick line which is put into variable function.
Hey guys, welcome to today’s tutorial. The need to measure time, to constantly know what the time of the day is, is something that will never get old, that’s why for today’s tutorial, we will be building an Arduino Real Time clock and temperature monitor using the big 3.2″ Color TFT display, the DS3231 Real time clock module, and the Arduino Due.
At the heart of today’s project is the DS3231 real time clock module which is being used to obtain the current time, date and the temperature of the environment. The DS3231 real time clock module has been used in several projects on this website mostly due to its accuracy and it’s low power requirement which means it can keep time accurately for a longer period than most of the other real-time clock (RTC) module. some of the features of the DS3231 RTC module are listed below.
One of the important things when designing electronic systems that have displays is ensuring that there is no flicker or lag when uploading information to the screen and one of the best ways to ensure that is to use a fast enough micro-controller, that’s why, for this project, we will be using the very fast Arduino Due development board. The Arduino Due has one of the fastest CPU speed in the family of Arduino development boards. The Due runs on an 84MHz CPU speed compared to the 16MHz CPU speed of the Arduino and as such, it is able to update the screen without any visible flickering.
Our goal for this project is to build a real-time clock with a user-friendly interface capable of displaying (without lag or Flickering) the current time, date, temperature including the minimum and maximum temperature measured over time.
The 3.2″ TFT like most TFT displays comes as a shield which can be easily mounted on the Arduino Due thus male headers will be used (after bending them as shown in the video) to connect the RTC module to the Arduino as the Screen will cover all the GPIOs of the board when it is plugged in and this may make connecting jumper wires to the board difficult.
To program the Arduino to display time and temperature data alongside the GUI on the 3.2″ TFT display we will require two libraries. The first library is the Bodmer TFT HX8537 Arduino Due library for the TFT display which is a modified version of UTFT library because this display does not work directly with the UTFT library due to driver compatibility Issues, but the code should work for any other version of the display that supports the UTFT library. The second library that we will be using is the Sodaq DS3231 library to enable the Arduino interface easily with the DS3231. These libraries can be downloaded via the links below.
Next is the void setup function. We initiate communication with the RTC module then Intitalze the display setting our preferred orientation for the display and Displaying the UI.
With this done, we then move to the void loop function. Under this function, we write the code to update all the parameters on the display including the min temperature, the max temperature, the time and the date.

This project aims to build a FlipClock style alarm clock (software emulated flips on a small screen) like the one used in the movie Groundhog Day, and play "I"ve got you babe" (or other sound clip).
Initially I"m borrowing code and information from HACKADAY.IO https://hackaday.io/project/167162-flipclock which already has the clock functionality using an Arduino Uno, a DS3231 Real Time Clock module and a shield based 3.5" TFT LCD display.
The hackaday project almost completely uses all available space for extra functionality, so I will have to remove all the uneeded fancy alternate display modes, and add a JQ6500 mp3 player and a PAM8610 audio amp (or similar). Alarm code will also need to added.
In electronics world today, Arduino is an open-source hardware and software company, project and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices. Arduino board designs use a variety of microprocessors and controllers. The boards are equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (‘shields’) or breadboards (for prototyping) and other circuits.
The boards feature serial communications interfaces, including Universal Serial Bus (USB) on some models, which are also used for loading programs. The microcontrollers can be programmed using the C and C++ programming languages, using a standard API which is also known as the “Arduino language”. In addition to using traditional compiler toolchains, the Arduino project provides an integrated development environment (IDE) and a command line tool developed in Go. It aims to provide a low-cost and easy way for hobbyist and professionals to create devices that interact with their environment using sensors and actuators. Common examples of such devices intended for beginner hobbyists include simple robots, thermostats and motion detectors.
In order to follow the market tread, Orient Display engineers have developed several Arduino TFT LCD displays and Arduino OLED displays which are favored by hobbyists and professionals.
Although Orient Display provides many standard small size OLED, TN and IPS Arduino TFT displays, custom made solutions are provided with larger size displays or even with capacitive touch panel.

Hey guys, welcome to today’s tutorial. The need to measure time, to constantly know what the time of the day is, is something that will never get old, that’s why for today’s tutorial, we will be building an Arduino Real Time clock and temperature monitor using the big 3.2″ Color TFT display, the DS3231 Real time clock module, and the Arduino Due.
At the heart of today’s project is the DS3231 real time clock module which is being used to obtain the current time, date and the temperature of the environment. The DS3231 real time clock module has been used in several projects on this website mostly due to its accuracy and it’s low power requirement which means it can keep time accurately for a longer period than most of the other real-time clock (RTC) module. some of the features of the DS3231 RTC module are listed below.
One of the important things when designing electronic systems that have displays is ensuring that there is no flicker or lag when uploading information to the screen and one of the best ways to ensure that is to use a fast enough micro-controller, that’s why, for this project, we will be using the very fast Arduino Due development board. The Arduino Due has one of the fastest CPU speed in the family of Arduino development boards. The Due runs on an 84MHz CPU speed compared to the 16MHz CPU speed of the Arduino and as such, it is able to update the screen without any visible flickering.
Our goal for this project is to build a real-time clock with a user-friendly interface capable of displaying (without lag or Flickering) the current time, date, temperature including the minimum and maximum temperature measured over time.
The 3.2″ TFT like most TFT displays comes as a shield which can be easily mounted on the Arduino Due thus male headers will be used (after bending them as shown in the video) to connect the RTC module to the Arduino as the Screen will cover all the GPIOs of the board when it is plugged in and this may make connecting jumper wires to the board difficult.
To program the Arduino to display time and temperature data alongside the GUI on the 3.2″ TFT display we will require two libraries. The first library is the Bodmer TFT HX8537 Arduino Due library for the TFT display which is a modified version of UTFT library because this display does not work directly with the UTFT library due to driver compatibility Issues, but the code should work for any other version of the display that supports the UTFT library. The second library that we will be using is the Sodaq DS3231 library to enable the Arduino interface easily with the DS3231. These libraries can be downloaded via the links below.
Next is the void setup function. We initiate communication with the RTC module then Intitalze the display setting our preferred orientation for the display and Displaying the UI.
With this done, we then move to the void loop function. Under this function, we write the code to update all the parameters on the display including the min temperature, the max temperature, the time and the date.
