Arduino Controlled Relay Box

Step 6 Test with an Arduino

You are now done with your project. If you've wired everything up then you're ready to test out the box. I tested mine with my arduino. Below is some code you can use to test yours out too. In this case I connected up the red wire to +5V, the black to ground, and the green to digital pin 12.

Here's the code I used:

Next I plugged in the extension cord and plugged a lamp into my new box. I uploaded my code, ran the program, and watched the lamp turn on and off. If you've done it right you'll hear a loud click noise when the relay is tripped on or off and the LED will light up inside the box. If your light doesn't turn on then you may have to hit the "RESET" button on the outlet. When the outlet is on you may also see an LED turn on on the outside of your outlet.

I hope this project worked for you. You'll find this useful in a number of great projects, so go out and make something fun!
