Circuit Diagram and Working: In this Arduino Relay Control Circuit we have used Arduino to control the relay via a BC547 transistor. We have connected transistor base to Arduino pin A0 through a 1k ...

In this project we control direction and speed of a 24v high current motor using Arduino and two relays.No power switches are needed for this circuit, just two push buttons and in Potentiometer to ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one. Aspencore network. ... circuit diagrams and ...

It works in two different modes, Normally Open (NO) and Normally Closed (NC). in our project, we will use it in Normally Open mode which means when the relay is switched off the circuit will be broken ...
