The resistor is used to limit the current that is being drawn and is called a current limiting resistor. The first step in this project is to design a simple LED circuit. Then we will make the LED circuit controllable from the Raspberry Pi by connecting the circuit to the general purpose input/output (GPIO) pins on the Raspberry Pi.Ī simple LED circuit consists of a LED and resistor. Raspberry Pi 3 setup with monitor and USB Mouse & Keyboard.We will need the following tools to complete the project: This tutorial will guide you through setting up the circuit, connecting it to the Raspberry Pi and how to write the Python script that makes the LED blink. A great way to get started with electronics and the Raspberry Pi is hooking up a red LED and making it blink using a Python script.
