I am working on a Project for myself and I am stumped as to how to go about the project.
I have a pressure transducer that i want the Arduino Uno to monitor the voltage, i than want to be able to set a value in the Arduino (1.6v) to than switch a relay in the relay shield that i have to turn off a solenoid.
i don't want the solenoid to turn back on until i press a button to activate the solenoid, than switch back off once the value (1.6v) is reached again.
i can find anywhere that some one has split the control circuit for the Arduino and the shield.
If anyone could shed some light on my project i will be very grateful.
