Arduino IDE file for a 1602 LCD pixel and backlight check
This is a simple Arduino (and C++) repo for testing your LCD display type LCD1602 or LCD1602A.
If you have an Liquid-crystal display type LCD1602 or LCD1602A you can connect as the schematic and upload the sketch.
As a result you will get the "Odd" and "Even" pixels one at the time.
- Connect the 1602 LCD according to the schematic
- See schematic pinsettings
- After upload to the arduino every second you'll see the even or the odd pixels lite up...
Odd | Even |
