In a previous article, we explored the behavior of an LED diode as a small light source. We have seen how important a protection resistor is to light up this component. In this article, we will ...

The project is a 12” digit height 7-segment display which was made from 15×4 LEDs wherein 4 LEDs are connected in series and fifteen times in parallel arrangement. The project is a 12” digit height ...

[Sean Hodgins] has a knack for coming up with simple solutions that can make a big difference, but this is one of those “Why didn’t I think of that?” things: addressable seven-segment LED displays.
