Arduino UNO output info! PLEASE!
Does a Arduino UNO have enough output voltage and amperes to trip a standard automotive 12v dc relay?
If not what do I need to trip the relay.
I am looking to control multiple relays (4) that would carry higher volts and amps to control a 12 v dc motor.
If the UNO does not have that capability, what would you suggest?
Thank You!No, you can’t directly trip a relay using an Arduino’s digital outputs. This is true for the majority of common microcontrollers.
We do have a few products that will let you work around this issue and drive relays using an Arduino:
– Boards with relays on them already –
