Topic: how can i get an uno to control a 12v device (Read 1 time) previous topic - next topic


so i need the arduino to power on a 12v fan then a 12v peltier then power off the peltier and then the fan with controllable delays, i should be able to do the code but i don't know if it will be able to run the 12v devices as it says it has a 5v operating power? i am ok with code but have no clue about hardware, i just wanted to know if i needed a different board or extra stuff before i ordered



Use an NMOS to drive the Load. Look for IRF1010E or similar it should do the job. You should check the Gate Threshold voltage, it has to be smaller than 5V.

Best regards,



use a relay board. They come in different variants with 1, 2, 4, 6, 8, 16 relays on one module.
