Turning on an LED with your Raspberry Pi's GPIO Pins
One of the biggest selling points of the Raspberry Pi is its GPIO, or General Purpose Input/Output ports. They are the little pins sticking out of the circuit board and allow you to plug various devices into your Pi. With a little programming, you can then control them or detect what they are doing. In this tutorial I am going to show you how to light an LED. In addition to your Raspberry Pi running Raspbian, what you will need is: A Breadboard An LED A 330 ohm resistor Two Male-Female jumper wires You can get all these, and more, in the £5 CamJam EduKit from The Pi Hut, which teaches you more about LEDs, buzzers and switches, and includes all the hardware and eight well-written worksheets about using the GPIO pins on your Pi. The Breadboard The breadboard is a way of connecting electronic components to each other without having to solder them together. They are often used to test a circuit design before creating a Printed Circuit Board (PCB). The ho
