Raspberry Pi is my hobby and I thought of sharing with you about these tiny projects. This will be a multi article series. Let us start with how to connect a I2C LCD display with the Raspberry Pi.

When you buy the LCD module, you can purchase LCD, I2C adapter separately and solder it. If soldering is not your thing, then it is better to buy the LCD module that comes with the I2C adapter backpack with it.

The above image is backside of a 2004 LCD module. The black thing is the I2C adapter. You can see the four pins GND, VCC, SDA and SCL. That’s where the you will be connecting the Raspberry Pi.

Raspberry Pi GPIO pins are natively of 3.3V. So we should not pull 5v from Raspberry Pi. The I2C LCD module works on 5V power and to make these compatible, we need to shift up the 3.3V GPIO to 5V. To do that, we can use a logic level converter.

You might see RPIs connected directly to a 5V devices, but they may not be pulling power from RPI instead supplying externally. Only for data / instruction RPI might be used. So watch out, you might end up frying the LCD module or the RPI itself.

As you know my language of choice to build website is PHP. But for IoT with Raspberry Pi, let us use Python. Reason being availability of packages and that will save ton of effort. Low level interactions via serial or parallel interface is easier via Python.

Following code imports the RPLCD library. Then initializes the LCD instance. Then print the “Hello World” string followed by new line. Then another two statements. Then a sleep for 5 seconds and switch off the LCD backlight. Finally, clear the LCD screen.

In this article, I will tell you about top 10 best Raspberry Pi kits, which are also available on Amazon. If you guys want, you can also buy these kits from the official website of SunFounder. Apart from the kits, you will also get many other things. for example, touch screens, Arduino boards, robots, end sensors, etc. Personally, I am very impressed with SunFounder’s products. Recently, I used SunFounder’s 13.3″ FHD 1920 x 1080 Portable IPS Monitor, I wrote a detailed article on it, and also made a very detailed video on it, which you can watch. I was simply more than surprised to see the quality of the SunFounder products.

So, I thought why not write a detailed article on SunFounder kits, so that many beginners, intermediate, and advanced level users can reach quality kits. Apart from the SunFounder Raspberry pi kits I have also included other kits which doesn’t belong to SunFounder. As my personal preference, when it comes to the Raspberry Pi, I always first go for the SunFounder, and if I don’t find it on the SunFounder then I go and search other websites. Anyhow.

Believe me, even after so many years of experience, I still use kits. Whenever, I work on a new project, I need some basic things to check my code properly. In the top 10 Raspberry Pi kits that I am going to share with you guys, in these raspberry pi kits you will find components from beginners to the advanced level, which I am sure, will always come in handy for you guys.

In my quest to find the best display for my Raspberry Pi, I tested a bunch of solutions, including other SunFounder products and standard monitors. I was excited to test the RasPad, as it seemed like a high-end product and likely a solid competitor to find a place on my desk ;-).

Note: To be transparent, SunFounder/RasPad sent me this tablet for free, to test it and write a review about it. But I’m free to share with you my honest opinion about it, just know that I didn’t pay it, maybe it can play a role in my impressions.

Anyway, once done, the last step is to install the cooling system. SunFounder includes 3 heat sinks in the box, and there is a fan on the other part of the case that you need to plug on the mainboard:

A hybrid usage, with an external monitor, works well too. You can use it like a laptop plugged on a second monitor while in your office, and take it with you when needed (like watching movies or playing games on your TV, run code to control your robot, etc.).

I have tested many operating systems (most of them based on Debian), and I didn’t experience any issues. I think the touchscreen should work on most operating systems natively, as it’s plugged via the USB port, but I haven’t tested everything, so feel free to contact SunFounder if you have any questions.

As an example, it ran for 2h18 with YouTube playing music. It’s far from the 5 hours announced, but it’s one of the most consuming usage, so it’s decent. If you are just editing and executing some code for a project, it will probably be more than that.

There is also a hole on the back for the camera module. I would have preferred the hole to be next to the GPIO one, but it’s an option if you really to use your Raspberry Pi camera, just find a long cable because the default ones are too short for this :).

If you are using your RasPad for basic usage (desktop, experiments, server, code, etc.), you can probably safely remove the fan if it’s too noisy for you.My test started around 50° C, keep an eye on the temperature, if you stay under 70 °C it’s perfect, if not consider the second option.

Note: I travelled once with the RasPad in my backpack. I found it turned on when arriving, the power button has been pressed during the trip, it’s not protected from accidental power on. Sunfounder if you are reading this, something like the smart cover of any similar protection would be a good idea (for the screen and the sides).

For me, it’s perfect. I’m testing new things all the time on my Raspberry Pi, I need a screen to see what happens and if the touchscreen is supported, my tests will be even fast. The screen size is good (doesnt’t take too much space and not as small as the SunFounder 7″ I used before that).Patrick

Connecting an LCD to your Raspberry Pi will spice up almost any project, but what if your pins are tied up with connections to other modules? No problem, just connect your LCD with I2C, it only uses two pins (well, four if you count the ground and power).

In this tutorial, I’ll show you everything you need to set up an LCD using I2C, but if you want to learn more about I2C and the details of how it works, check out our article Basics of the I2C Communication Protocol.

BONUS: I made a quick start guide for this tutorial that you can download and go back to later if you can’t set this up right now. It covers all of the steps, diagrams, and code you need to get started.

There are a couple ways to use I2C to connect an LCD to the Raspberry Pi. The simplest is to get an LCD with an I2C backpack. But the hardcore DIY way is to use a standard HD44780 LCD and connect it to the Pi via a chip called the PCF8574.

The PCF8574 converts the I2C signal sent from the Pi into a parallel signal that can be used by the LCD. Most I2C LCDs use the PCF8574 anyway. I’ll explain how to connect it both ways in a minute.

I’ll also show you how to program the LCD using Python, and provide examples for how to print and position the text, clear the screen, scroll text, print data from a sensor, print the date and time, and print the IP address of your Pi.

Connecting an LCD with an I2C backpack is pretty self-explanatory. Connect the SDA pin on the Pi to the SDA pin on the LCD, and the SCL pin on the Pi to the SCL pin on the LCD. The ground and Vcc pins will also need to be connected. Most LCDs can operate with 3.3V, but they’re meant to be run on 5V, so connect it to the 5V pin of the Pi if possible.

If you have an LCD without I2C and have a PCF8574 chip lying around, you can use it to connect your LCD with a little extra wiring. The PCF8574 is an 8 bit I/O expander which converts a parallel signal into I2C and vice-versa. The Raspberry Pi sends data to the PCF8574 via I2C. The PCF8574 then converts the I2C signal into a 4 bit parallel signal, which is relayed to the LCD.

Before we get into the programming, we need to make sure the I2C module is enabled on the Pi and install a couple tools that will make it easier to use I2C.

Now we need to install a program called I2C-tools, which will tell us the I2C address of the LCD when it’s connected to the Pi. So at the command prompt, enter sudo apt-get install i2c-tools.

Next we need to install SMBUS, which gives the Python library we’re going to use access to the I2C bus on the Pi. At the command prompt, enter sudo apt-get install python-smbus.

Now reboot the Pi and log in again. With your LCD connected, enter i2cdetect -y 1 at the command prompt. This will show you a table of addresses for each I2C device connected to your Pi:

We’ll be using Python to program the LCD, so if this is your first time writing/running a Python program, you may want to check out How to Write and Run a Python Program on the Raspberry Pi before proceeding.

I found a Python I2C library that has a good set of functions and works pretty well. This library was originally posted here, then expanded and improved by GitHub user DenisFromHR.

There are a couple things you may need to change in the code above, depending on your set up. On line 19 there is a function that defines the port for the I2C bus (I2CBUS = 0). Older Raspberry Pi’s used port 0, but newer models use port 1. So depending on which RPi model you have, you might need to change this from 0 to 1.

The function mylcd.lcd_display_string() prints text to the screen and also lets you chose where to position it. The function is used as mylcd.lcd_display_string("TEXT TO PRINT", ROW, COLUMN). For example, the following code prints “Hello World!” to row 2, column 3:

On a 16×2 LCD, the rows are numbered 1 – 2, while the columns are numbered 0 – 15. So to print “Hello World!” at the first column of the top row, you would use mylcd.lcd_display_string("Hello World!", 1, 0).

You can create any pattern you want and print it to the display as a custom character. Each character is an array of 5 x 8 pixels. Up to 8 custom characters can be defined and stored in the LCD’s memory. This custom character generator will help you create the bit array needed to define the characters in the LCD memory.

The code below will display data from a DHT11 temperature and humidity sensor. Follow this tutorial for instructions on how to set up the DHT11 on the Raspberry Pi. The DHT11 signal pin is connected to BCM pin 4 (physical pin 7 of the RPi).

By inserting the variable from your sensor into the mylcd.lcd_display_string() function (line 22 in the code above) you can print the sensor data just like any other text string.

These programs are just basic examples of ways you can control text on your LCD. Try changing things around and combining the code to get some interesting effects. For example, you can make some fun animations by scrolling with custom characters. Don’t have enough screen space to output all of your sensor data? Just print and clear each reading for a couple seconds in a loop.
