Traffic Light Module by Bits4Bots
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.
