In this section we’ll install the wiringPi library on the Raspberry Pi, connect up a single LED, and write a simple program in C to make it flash. You don’t need a keyboard or monitor for this tutorial – if your Pi is on the network you can log in via ssh and do everything from a terminal. I usually like to build the circuit on a breadboard first. Just to make sure I understand it and am able to build it before soldering it onto a prototyping board.

There we go. Now you’ve got all your stuff together, put it to one side and let’s focus on getting the code ready before we do any connecting up. Step 2 – Write Some CodeNote: The 4017 IC must be connected plus and minus through pins 16 (+) and 8 (-) for it to work. Components Needed Note that when you CTRL-C out of the program, your LED may remain on – this will happen if you interrupt the program before the GPIO pin is told to stop the output. It will be reset when you run your code again, but you may want to avoid pulling wires in and out when the GPIO pin is active, just in case. This guide is for complete beginners, so I’ll be talking through all the parts and the entire process step by step. The LED bridges to another row, 55, and the circuit continues into our resistor, which is also plugged into row 55.

If you’ve never done any electronics or embedded work before, this can seem like a daunting task, but it really isn’t.
