5V Traffic Light Model Soldering Kit

Build a small traffic-light model with a soldering-practice kit that includes LED signals and countdown displays.

✅ See the circuit produce a sequence - Coloured LEDs and digital displays provide a visible result from the assembled project.

✅ Practise component assembly - A DIY kit format turns the model into a hands-on soldering activity.

✅ Power from a suitable USB source - A micro-USB input supports the described external 5 V supply arrangement.

Follow the circuit from components to countdown

A traffic-light model gives soldering practice a clear purpose: assemble the parts and observe the light sequence. The countdown displays add another visible element to discuss during an electronics lesson.

This is a kit, not a finished road-control device. Check component positions and polarity while building, then inspect the assembly before applying the specified power; use suitable supervision and soldering protection.
