Seven-segment displays have been around for a long time, and there is a seemingly endless number of ways to build them. The latest of is a mechanical seven-segment from a master of 3D printed ...

We’re used to seeing all manner of seven-segment displays, be they mechanical, electronic, or something in between. But what all these displays have in common is that they’re, you know, displays.

If we set things up correctly, we could create a string of these displays daisy-chained together, and drive the entire string using only a single pin from our main MCU. If we set things up correctly, ...

Seven-segment displays are needed in many instrument designs. In conventional microcontroller-based designs, four output port lines are allocated for one seven-segment display. Figure 1 shows the ...

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 ...
