DownloadSometimes there is a need to control some hardware by commands sent over a serial communication channel.
In this version, 4 channels are implemented that can be turned on or off individually, or all at once.
The command is in the form: [A|B|C|D|*][0|1]+newline.
For example :
- A1 activates channel A
- A0 deactivates channel A
- *1 activates all channels simultaneously
- *0 turns off all channels simultaneously
To avoid "autoreset" of the Arduino NANO, which is necessary for the correct operation of the board, it is necessary to remove the capacitor shown in the image. You will always be able to reprogram the processor by pressing the little RESET button, before loading the sketch.
Using the board without this modification, commands will not be executed and the board will reset with each command sent via serial
