This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

In a way, all 7-segment displays are alike; at least from the outside looking in. On the inside it can be quite another story, and that’s certainly the case with the construction of this Soviet-era ...

Sometimes, a good hack is about using less rather than more. That’s the case with this neat tutorial from [Rahul.S] on driving a 7-segment LED display with an FT232. By using this cheap USB to serial ...

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 ...
