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 ...

The seven-segment display is most well known in LED form, but the concept isn’t tied to that format. You can build a seven-segment display out of moving parts, too. [tin-foil-hat] has achieved just ...

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 ...

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 ...
