HVAC Power Relays HVAC Troubleshooting Circuit Diagram Safely control AC equipment using an Arduino. Learn how to use Relays and Solid State Switches to build a light-activated relay and a marquis light chaser. After you wire it up you can load some code. Relay Module Sketch. The sketch for the light-sensitive relay is shown here:
This includes controlling AC/DC lighting, controlling dc motors, heaters, As previously discussed in earlier tutorial PWM motor speed control, an inductive load can generate a sudden high Back Electromotive Force (Back-EMF) when the solenoid of the relay coil is deactivated. This Back-EMF can potentially damage electronic components unless

Controlling AC Light Using Arduino With Relay Module Circuit Diagram
An 8-channel relay module is useful for more complex projects, such as home automation systems. Each relay in a multi-channel module works independently, so you can control them individually using separate Arduino pins. The wiring and code are similar to a single-channel relay, but you need to specify the appropriate control pin for each relay. At the heart of this circuit is a 5V relay, which acts as an intermediary to switch the high-power AC load while being controlled by a low-power DC signal.Here's a breakdown of the components and their roles: Battery (9V): Supplies power to the control circuit. Switch (SW1): Turns the entire circuit ON or OFF. NPN Transistor: Amplifies the control signal to drive the relay.
