Project 1 : How to make a Traffic light 🚦 with Menya IoT Kit.

Traffic lights are a set of color coded signals installed at busy road intersections or junctions. A road signal for directing vehicular traffic , typically red for stop, green for go, and yellow for proceed with caution. Also called stoplight, traffic signal.

The Menya IoT kit traffic light is a fun little project that you can build in under an hour. Here’s how to build your own.
