Control 5V Relay With 3.3V. Arduino is a 5v (some are 3.3v) system, so we can easily control any 5v device using an arduino output pin. — i have some circuit where my board (electric imp) can output up to 3.3v, and i need to control a relay with atleast 5v in order to effect the coil. you are going to need to obtain (or create) a 5 volt supply. — arduino relay tutorial. — since the arduino operates at 5v it can’t control these higher voltage devices directly, but you can use a 5v relay to. If you search for step up breakout you will find products that can step up 3.3v to 5 volts. — i need to control a 5v relay board with a 3.3v arduino pro mini. • connect the vcc pin of the relay board to a 5v. the circuit will work with 0/3.3v input (anything from a bit over 1v to more than 10v is an acceptable '1', and < 200mv is '0'). — yes, the reddit post's approach is likely to work ok, as long as you correctly follow the cautions in it: The relay board is the type that uses an opto.
