I am currently creating a piece that requires 5 solenoids to be activated simultaneously by a proximity sensor.
I am now having difficulty with the external power. if each solenoid is 12v I will need a total of 60v then (less is okay)... to measure amperage I can just use a multi-meter? will it need to have a load when measuring?
SHOULD I combine all voltage and use a 60v power supply? or make my life easier and use multiple adapters? it is the amperage that is confusing me.
(first terminal is coming in from arduino pin 13, all share arduino GRND, and second terminal is where power supply will be)
Would really appreciate some feed back!!! thanks
there are diodes so please ignore the (diodes??)
attached is my code;
