Arduino AC Power Control Tutorial - bristolwatchcom

I have my Arduino powered by a regulated 5v power supply. I have another regulated 12v power supply connected to the 2nd ground and Vin of the Arduino, but I am unsure if this is necessary. Regardless of this, my relay was not switching the power on/off.

Arduino Tutorial #1 - Digital Inputs and Outputs - Button

The pin D3 of the Arduino is connected to the resistor. Just like when using an LED, this limits the current flowing into the transistor through the base. There is a diode connected across the connections of the motor. Diodes only allow electricity to flow in one direction (the direction of their arrow).

A Solenoid Tutorial. The bypass diode. The schematic shows a bypass diode, D1. When the solenoid is on or idle this diode will not conduct. You do need to connect your Arduino ground to the ground shown on the circuit and also place a 10k resistor from the gate to ground to make sure it stays off unless the arduino pushes it on. FET
