I have a small PCB mounted relay that I want to control with an Arduino. The coil spec is 5V, 125 ohms, 40mA. That's the max current an Arduino output can handle. Should I put a something across the coil to reduce voltage spikes? Snubber, fly back diode, etc? If so, what?
The relay I'm using is V23105A5301A201
