There’s something about clocks — sooner or later, every hacker wants to build one. And we end up seeing all kinds of display techniques being used to show time. For the simplest of builds, 7-segment ...

Sample Program 2: Display decimal numbers from 0-9 in the seven segment display. As we learn the basic idea about programming and how to run and execute it in the previous module (module -4), its time ...

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 ...

There’s a long history of devices originally used for communication being made into computers, with relay switching circuits, vacuum tubes, and transistors being some well-known examples. In a smaller ...

Reddit user Krukerfluk has created an awesome DIY digital clock using 144 x seven segment displays, combining them to create a larger LED display powered by an Arduino Nano. The small Arduino ...

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 ...
