i need to use a wall wart power supply for a beefcake relay. The relay is attached to an arduino uno but that power supply is already running the arduino and a lcd screen. I have a 6.0 v 200ma wall wart . Would this work or can the relay only handle a maximum of 5 v? the relay and arduino are running in an enclosed but not airtight space. thanks
