There’s a priceless feeling of pride when you assemble hardware, together with software, creating a masterpiece.
No matter how long you’re tinkering with tech, that feeling never seems to go away.
You’ll want to wire up the 5V relays similar to those shown in the image above.
The first (left) terminal does not get used on the 5V Relays.

Creating the Code
First, slide over to our GitHub repository todownload the code.
Let’s review a few important code snippets to understand what’s going on.
Having the ability to importrandom,machine, andtime/sleepfunctionality makes this coding project really simple.
The example code prints the output of(lights); however, this is not required.
On the other hand, you may want to keep it in the code until you’re finished troubleshooting.
For testing purposes, this function was commented out in the example code.
With that said, there is generally more than one way to perform a task.
Review our comparison betweenRPi.GPIO versus GPIO Zerofor details.
Now, the final result.
