5VDC Red Yellow Green Traffic Light Module
Have too many robots moving around your house? This Traffic light can be a nice feature that you can add to your autonomous city diorama. It can be used as a light at an intersection or a train track warning light. It consists of three 5mm LEDs with pulldown resistors so all you need to do is connect the pin corresponding to the desired colour to a 5VDC source and your LED should light up!
