LED Traffic Lights - Twin Pack
Now available from PMD Way are these useful and fun traffic light style LED boards.
Each board contains three 5mm LEDs - red, yellow and green in a nifty vertical arrangement, just like traffic lights.
The board is fully assembled and includes resistors for the LEDs so you can safely run them from 5V or 3.3V DC, and thanks to the inline header pins you can drop it straight into a solderless breadboard or Arduino as shown in the images.
Sold in packs of two.
