10mm red, yellow, and green LEDs on a traffic signal shaped PCB. Designed to have the same physical features of a traffic light with 4 pins.

What is it?

Traffic light shaped printed circuit board module. Great for Arduino, micro:bit, Raspberry Pi, and other development boards.

Why did you make it?

To add a working traffic signal to electronic projects, STEM kits for kids, and microcontroller learning.

What makes it special?

Its unique shape and large easy to hold circuit board for ages 8+

It has x3 10mm LEDs (1 Red, 1, Yellow, 1 Green). Each of these LEDs can be driven from one of the IO development board pins.

For micro:bit use P0, P1, and P2 for the connections between the LEDs and the IO pins. Arduino can use any digital IO and likewise for Raspberry Pi's.
