lcd display with push buttons factory

IS-DEV KIT-1: One SMARTSWITCH™ programmable LCD display module and two PCB mounted tact switches, with flash memory, power and programming connections.

If Push Button 2 is pressed/released, then the LEDs changes their state (RED—GREEN—ORANGE—OFF), and corresponding state change is displayed on the LCD screen."""

Combining pushbuttons with LCDs can go a long way when making Arduino projects. Take a vending machine for example. A vending machine works by making a payment to receive the appropriate product. Usually, it is self-service and you only need to interact with buttons and an LCD for instructions and feedback. Another device that uses LCD and buttons to work properly and efficiently is the printer. You can set options by pressing the appropriate buttons with instructions displayed on the LCD.

This is Project 51 of the Arduino Intro app. This is an example of how to select modes or settings using a pushbutton and displaying the choice entered by the user on the LCD.

This project uses the I2C LCD. For more details on how to use this LCD, you may read this article: Displaying Characters Using the I2C Liquid Crystal Display (LCD)

We will be using the variable valto store the current value of the pushbutton. Every time the button is pressed, its value becomes 1, otherwise, its value is 0. However, in some cases, this might be reversed. When the button is pressed, its value becomes 0, otherwise, it is 1. You may change this later on in the code. You can use the serial monitor to check the value or you may use a simple trial and error. The led_num keeps track of how many times the button is pressed and this corresponds to the current mode selected.

This is Project 52 of the Arduino Intro app. It displays the status of the LED, whether it is turned on or off. A single pushbutton will turn on/off the LED.

This sketch uses the "Sticky" pushbutton effect. What happens here is that when the button is pressed, the LED turns ON and it STAYS ON even when you release the button. The next time you press it, the LED turns OFF and it STAYS OFF until the next press of the button. This is explained further in this article: Using Simple Pushbutton Switches to Light Up LEDs

Unlike other "Serial Display" which just convert serial input to parallel, Digole"s Serial displays and adapters embedded a powerful MCU to process the commands received, display characters and control back light as you want, all commands are simple, high level and easy to remember!

CLear screen and set the display position to first Column and first Row (x=0.y=0), for graphic LCD, it also set the font to default and turn off the cursor.

Display Config on/off, the factory default set is on, so, when the module is powered up, it will display current communication mode on LCD, after you design finished, you can turn it off

display TexT string, the text will wraped in next row if the current row fulled, the Text Postion will be changed to the last char displyed, this command ended by 0x00 or 0x0D received
