What could be better than one LED? Full of LEDs! It allows to realize small displays using 8x8 matrix or 7-segment 4-digit displays. Such matrices use 'multiplexing'. To control 7 LED segment, you need 14 pins. So that's a lot of pins, there are many control circuits like the MAX7219
to manage matrices but it requires a lot of connections that use a ton of space.
AdaFruit has of course found a solution to this heavy situation and has developed a breakout to control tons of LEDs matrix or segment without having to spend half of the day to make connections :-)
This breakout comes in two versions: one for controlling a 8x8 mini matrix
and 4-digit, 7-segment sections. Adding LED displays to your projects becomes totally trivial.
Some welding operations are needed to attach the LED/display matrix to the control board. Same for the pinHeader if you want to use it.
This operation should not take more than 5 minutes.
If you are interested by a LED matrix (or equivalent) but complexity is an obstacle to take the plunge... this option is the solution you were looking for!
