Erstaunlich Arduino Relay Schaltplan Bilder. You can watch the following video or read the written tutorial below. Interface arduino 5v relay and control ac appliances. In this arduino project, you will build a small relay shield from stripboard.
This article shows how to control mains voltage with the arduino using a relay module.
The relay is a small device that can control up to 230v devices. What is a relay module? A relay accomplishes this by using the 5v outputted from an arduino pin to energize the electromagnet. While connecting the load make sure that relay is capable of. A relay is an electrically operated switch that you can use to control mains voltage appliances. As you can see, controlling the relay with the arduino is as simple as controlling an output where you just need to send high or low. In this arduino project, you will build a small relay shield from stripboard. Or when the resistance of a photoresistor. The shield can have one or two relays fitted to it. * a relay basically allows a relatively low voltage to easily control higher power circuits.
