Hi guys , completely new to arduino. i have played around with a program from the internet.
I have a watering system controlled with a siemens LOGO ( my background)
The water is gravity feedingfrom the pumps designed a 3d print for a ball valve holder workes well but the servo chatters when at either "90" degrees or "0" degrees.
also i can only get one servo to run as i want it . if i uncommenet the the other inputs and servo i get strange things happening to the first / second servo
Any idea what i'm doing wrong
