Hi, im new to arduino and I want to start programming an automatic fish feeder in my Arduino but i have absolutely no clue about what the code is supposed to look like. I want it to turn a servo Motor a few steps every 12hours and when the motor is rotating a green LED lights up.The arduino must be plugged in the wall. does anyone can help me?
