Traffic Signal Controller – DIY Kit

Short Product Description

A hands-on electronics project where kids build a working traffic signal with real LEDs! This DIY kit introduces circuit basics, sequencing logic, and how real city traffic lights operate.

What’s Inside the Box

• Pre-cut wooden signal housing & pole

• Red, yellow & green PETG lenses

• LED set (Red, Yellow, Green)

• Battery holder (safe low voltage)

• Small wiring set

• Rubber bands, wooden pegs

• Illustrated instruction manual

How It Works

Kids assemble the wooden traffic signal, insert the colored lenses, and connect the LEDs following the wiring guide.
Once powered with the battery pack, the LEDs light up and can be sequenced manually or through a simple switch:

• Red → Yellow → Green

• Demonstrates how real traffic flow is controlled

• Kids learn how circuits power LEDs and how switching logic works

What Kids Learn

• Basics of electrical circuits

• LED polarity & safe wiring

• Sequencing logic of real traffic systems

• Observation & problem-solving skills

Perfect For
