The image shown below indicates the basic wiring diagram of the current limiting resistors and driver transistors. Next is the Hookup diagram of the Arduino 4-Digit 7-segment LED Display, followed by ...

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 ...

That’s right, [Kemley] is using point-to-point soldering to rig up this big display. It sports four sixteen segment modules on top for alpha-numeric information, and eight large seven segment ...
