In a previous article, we explored the behavior of an LED diode as a small light source. We have seen how important a protection resistor is to light up this component. In this article, we will ...
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 ...
Many options exist to drive seven-segment LED displays, but most are limited to low output currents. The approach described here uses one 74ALS374 or 74AS374 octal latch, wired as a shift register, ...
