Raspberry Pi, 2nd Edition

Build a Basic Circuit

To warm up, we’ll build one of the most basic circuits possible. We’ll connect an LED to the Pi and make it shine as long as the Pi is running. For this we’ll need an LED, a resistor, a breadboard, and two female/male jumper wires. Using these parts, we’ll build the circuit shown in the following figure.

Before we actually build the circuit, you should know what all the parts are for and how they work. Breadboards are useful tools for prototyping circuits. You can simply plug in parts such as LEDs and resistors, and you don’t have to solder them. Breadboards come in various sizes, but they all ...
