The 1K resistors are used for base current limiting, and the 390R resistors limits the operating current of the LED display segments. In the Arduino board, digital outputs from D2 to D8 are used to ...

Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push button increment of the counter from 0 to 9. The whole circuit can ...

By combining addressable LEDs, light pipes and 7-segment displays, [TerraG2] has built a timepiece that looks great and will surely be a great conversation starter as well.

The 7-segment display certainly is a popular build, and surprisingly people still come up with new takes on this over a hundred-year-old way to represent numbers. This time [jegatheesan.soundarapan… ...

With the grey package surface, the untinted seven segments display light evenly. LED displays in the VDMx10A1 series feature common anode configurations and very low package heights of 2.1 mm.
