Traffic lights: common questions

What microcontroller does the Traffic lights use?

The Traffic lights is built around the ATmega8-16AU, from the AVR/Arduino family.

How big is the Traffic lights PCB?

The Traffic lights measures 26.4 × 61.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Traffic lights?

47 components, from 18 distinct parts. The full bill of materials is listed on this page.

Where can I download the Traffic lights design files?

From the ilusder/traffic_lights repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Traffic lights design in my own project?

The repository has no license, so all rights stay with ilusder. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Traffic lights without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
