Arduino Display Screen Sketch

Connect the display to the arduino.
Arduino display screen sketch. Our simple interface will just consist of three buttons one for each led. The example sketch above shows you the basics of displaying text on the lcd. If your oled display is not showing anything. This example reads the temperature of the esplora s on board thermisistor and displays it on an attached lcd screen updating every second.
Now we will take a look at the other functions of the liquidcrystal i2c library. I modified it to eliminate the other functions and just display three buttons. I then powered my display from my external 5v supply with common ground to the arduino which did the trick the display is now working properly. This example code is in the public domain.
Here is the sketch. While one can buy a cheap 320x240 lcd touch screen for an arduino based project it can be more convenient especially for prototyping and testing a sketch to use a tablet or phone as both a touch screen and a power source for a project. We are going to display typed message on lcd 16 2 display using serial monitor see where you can gather information on how to work with serial monitor and how to work with 16 2 lcd display and also gain the pleasure of technical knowledge. Waveshare 2inch lcd display module ips screen 240 320 resolution onboard driver st7789 spi interface rgb 262k color with examples for raspberry pi jetson nano arduino stm32 4 0 out of 5 stars 53 14 75 14.
The sketch is based upon the telephone keypad sketch. With the oled connected to the arduino upload this code and check the i2c address in the serial monitor you should change the oled address in the following line if necessary. Then i added code to toggle the leds. Clear clears the lcd screen and positions the cursor in the upper left corner first row and first column of the display.
This worked but only halfway the display fired up and started cycling the demos in the sketch we will see later on and then froze after a few seconds. Double check the oled display i2c address. Display custom bitmap graphics on an arduino touch screen and other arduino compatible displays. Your the display all you need do is copy the code of the drawbitmap function from the gfx library and paste it in the arduino sketch for your project such that it becomes a user defined function.
Check that the oled display is properly wired to the arduino. In this article we are going to link hardware and software of arduino with the lcd. Esplora tft temperature display this example for the arduino tft screen is for use with an arduino esplora. Tablet phone as arduino screen and a 2 oscilloscope.
