Arduino Street Traffic Light – Breadboard Edition

Build a simple Arduino powered Traffic Light with us! This instructable is meant to walk you through almost every step, but there are a few assumptions. Read over the intro and the first step to make sure you are fully prepared! This is the breadboard version, a more realistic traffic light will be generated soon. Please leave comments – tell us if things are confusing!

Supplies Needed:
1 x Computer with Internet Access
1 x Arduino Uno
1 x USB A/B Cable for connecting the Arduino to your PC
1 x Breadboard (Half-Size, with Voltage Rails)
1 x Red LED
1 x Yellow LED
1 x Green LED
3 x 100 Ohm Resistors (Brown Black Brown)
4 x Breadboard Wires (22 AWG, approx. 6+ inches in length)

Other Helpful Things:
– Good lighting
– A clean workspace
– An hour of your time
– Someone awesome to work with

Step 1: Set Up the Arduino Environment

This instructable makes many assumptions! Some people like to call these “prerequisites”. In order to make sure you get the most out of this instructable, you should have:
– The Arduino Software downloaded and installed on your computer.
– Plugged in and tested your Arduino by following the installation guide appropriate for your computer.
– Approximately one hour of time to spare, and a nice clean workspace with plenty of lighting.

Mission Complete? Continue on!
