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 ...

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 ...

Computers, from the simplest to the most complex, aren’t very useful if they can’t provide feedback to a user. Whether that interface takes the form of a monitor, a speaker, or a simple LED, there’s ...

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 ...
