Traffic Light LED Module

Traffic Light LED Module

SKU: Comp#15




Ever imagine how the traffic light works? Well, now you can do your own program for traffic light control with this Traffic Light LED module. Compatible with any micro controller, yes any micro controller that can output digital high or low like Arduino, Raspberry Pi, micro: a bit too. It is a common cathode LED so you just need four wires to the controller and logic high will trigger/activate the respective LED.

Traffic Light is one of the popular electronic projects among final year projects and RBT (Reka Bentuk Teknologi). Modeling or simulating an actual traffic light system just gets easier.

It is being arranged to be the same as normal traffic light where the Red is at the top, Yellow at the middle, and Green at the bottom. Additionally, this board uses a 5mm (diameter) size LED, offering a clear view of the light even in a compact size. Not to forget all three LEDs are diffused type so widening the viewing angle too.
