Hi Tom I yes I have written the code all at once, have tried to do it in stages but no luck,
The code is for the Arduino Mega AT 2560 to controll two linear actuators for solar tracker,using relays and LDR
I hope this will come out, so you can understand what I'm trying to do.
Look forward to hear from you.
Kind regards botvid.
I still got error, digitalWrite was not declared in this scope.``
