PROGRAM KC868 A16 DI, DO AND LIQUID CRYSTAL FROM ARDUINO IDE

[Cesarcardca]

I NEED PROGRAM KC868 A16 DI, DO AND LIQUID CRYSTAL I2C FROM ARDUINO IDE. Or if your recommendation is through esphome, I could also try it, I need the syntax, or the devices for inputs and outputs so I can manipulate my program since I also need to interrupt a sensor.

KC868-A16 all arduino demo source code on the forum, you can test with our demo source code.

Ok, I found the source code. but I get an error when trying to add the 20x4 LCD

I was able to solve it. It was lost from the wire.h library folder, this should be in the arduino folder

Continuing with the goal of using my KC868 A16 board on Arduino IDE to control water pumps, quick interruption sensors and a 20x4 LCD screen, I managed to compile and upload the first code to the board even though red letters appear.

Once compiled and loaded, 2 outputs are supposed to turn on and off every second but it does nothing.

see this photo, you have not connect with Vin RED cable.

see this photo, you have not connect with Vin RED cable.

I already did it but they still don't turn on, I searched for i2c devices and they couldn't be found. How can I solve it? It seems strange to me that the letters appear in red.
