    Very cheap and easy to use. The main library for it is available and well-known on the Internet, but requires a bit of skill to get working. 7-segment display was very bright. This could be considered a pro in some cases though. Also, the cable connected on the front of the board, which could it... Read more

    Article relatively easy to use, long as you have some help. It has many uses. It has everything I need to make a traffic light and a tachometer for scalextric.

    Easy to setup on Arduino using libraries found on the internet. The Arduino library is easy to use. Comes with the cable. Comes with screws for mounting the display. Red LED is brighter than the Green LED therefore showing both at the same time does not produce a yellow/orange colour but just are... Read more
