Stilvolle Arduino Relay Schaltplan Fotos. The arduino can be programmed to turn on the relay when a certain event occurs, for example when the temperature of a thermistor gets higher than 30°c. Interface arduino 5v relay and control ac appliances. A relay is an electrically operated switch that you can use to control mains voltage appliances.
A relay accomplishes this by using the 5v outputted from an arduino pin to energize the electromagnet.
In a previous tutorial, we have learned how to turn on/off an led. * a relay basically allows a relatively low voltage to easily control higher power circuits. The shield can have one or two relays fitted to it. Arduino tiny relay shield project. You can watch the following video or read the written tutorial below. Interface arduino 5v relay and control ac appliances. Here is the list of the elements we will be using in this project. In this tutorial we will learn how to control high voltage devices using arduino and a relay module. A relay accomplishes this by using the 5v outputted from an arduino pin to energize the electromagnet. 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.
