Since their being revealed to our community over a year ago, the various ultra-cheap microcontrollers in the sub-ten-cent price range have attracted a lot of interest but not so many projects. Their ...

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 ...

[Kratz] is working on a WiFi controlled scoreboard, but before building the full-scale version, he thought it would be wise to test out the multiplexing technique for the display. The experiment ...

This version of tutorial board is based on the popular PIC16F84A microcontroller which consists of an in-circuit programming header (ICP) in order to program the microcontroller directly on board with ...

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 uses classic LED 7-segment display from vintage LED watches and vintage calculators in order to create a digital clock. The design of this clock does not only come with these classic ...
