Overview
The Pi-Traffic Light is a simple and engaging way to incorporate three 10mm LEDs into your Raspberry Pi project. Featuring red, yellow, and green LEDs, it provides clear visual feedback from the Raspberry Pi GPIO. Additionally, the Pi-Traffic Light serves as an excellent educational tool for learning how to control the GPIO pins on your Raspberry Pi.

Installation
Raspberry Pi Model A+, B+, 2B, 3B, 4 and Zero (40-pin GPIO)
For Raspberry Pi models with a 40-pin GPIO header, the Pi-Traffic Light connects to GPIO pins 9, 10, and 11. When facing the front of the Raspberry Pi, these pins are located in the middle of the header. The Pi-Traffic Light is designed to be installed vertically on the four back-left pins of the GPIO header, as illustrated in the photo below.
Please note that for the Pi Zero, soldering pins into the 40-pin header is required for proper installation.

Pi Traffic Light can also be installed on GPIO pins GPIO26, GPIO19 and GPIO13
Raspberry Pi Model A and B (26-pin GPIO)
For Raspberry Pi Model A and B, the Pi-Traffic Light connects to GPIO pins 9, 10, and 11. When facing the front of the Raspberry Pi, these pins are located in the back-left corner of the GPIO header. The Pi-Traffic Light is designed to be installed vertically on the four back-left pins of the GPIO header.
