# Traffic Lights

> Traffic lights I made for computer engineering class, with printed housings, wiring, and a bench test.

3D-printed traffic lights for computer engineering.

I made these traffic lights for my computer engineering class, I believe Grade 11

Testing the traffic lights on the bench.

Printing the supports, and one of the traffic-light housings.

The printed parts before assembly, then the lights and wiring packed together.

Flowcharts for the crossing sequence.

An earlier light-timing draft and its revised north-south/east-west sequence.

The circuit layout in simulation.

Testing the traffic lights and crossing circuit in simulation.

Another view of the physical lights changing during the bench test.
