HANDS-ON PROJECT
PROJECT NAME: Automatic Traffic Lights
Software Used (Circuit): TinkerCad
Software Used (Sketch): Arduino IDE
Objective:
Learn to design and implement an automatic traffic light system using LEDs, breadboards, and
Arduino programming. This project will teach fundamental concepts of electronics, circuit design,
and basic coding skills using Arduino.
Step-by-Step Instructions:
Step 1 Connecting LEDs to a Breadboard
Identify the LED's anode (long leg) and cathode (short leg).
Use resistors to prevent damage due to excess current.
Connect the anode to the positive terminal and cathode to ground using jumper
wires.
Step 2 Designing a Tinkercad Circuit
Use Tinkercad to simulate the traffic light system:
o Add components like LEDs (Red, Yellow, Green), resistors, and an Arduino Uno.
o Wire the LEDs to Arduino pins (e.g., pin 9 for red, pin 10 for yellow, pin 11 for green).
o Test the connections virtually before building the physical circuit.
