In this Arduino tutorial, we’re going to learn how to control a relay with a button. This is a very similar tutorial to our button LED control tutorial, but with a relay! The main difference being that a relay will allow you to control something of higher voltage than the Arduino can...
Learn how to use button to toggle relay, button triggers light. The detail instruction, code, wiring diagram, video tutorial, line-by-line code explanation are provided to help you quickly get started with Arduino. Find this and other Arduino tutorials o
Press the button. You can now use ‘digitalWrite’ or other other functions to switch on an LED, relay, adjust PWM duty cycle (for example, increase the brightness of a lamp) whenever the button is pressed.A simple way to test this is to use an ‘if’ statement to check the value ...

For example, you can replace those LEDs with a relay to control your house appliances. This can be particularly useful because some remotes have a bunch of buttons that you never use. So, why not use them to do something useful?

The single bond button design provides a self-locking switch, which means that once activated, the relay remains in its state until manually deactivated. This feature is particularly useful for automating tasks or creating custom control systems. The module's compatibility with Arduino Uno and ...
