PIR sensor - Relay automatically turning ... - Arduino Forum

06/05/2021· That transistor is meant to switch the power to the relay, using the signal of the Arduino. A small enough relay MAY work on the Arduino's power supply, but it's definitely not recommended. You're quickly overloading the power supply and that may result in all kinds of weird behaviour (the most common, though, being a simple reset of the device). Code in #9 looks sound to me. dfvr1994 July 18 ...
