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 printe d 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. Show more
