In the early digital era, logic gates were made exclusively of transistors and discrete components. The obvious occupation of a large space and increased heat dissipation pushed technology to ...

This file type includes high-resolution graphics and schematics when applicable. Measuring the low frequencies that are common in many real-world situations, such as biomedical or speedometer ...

Although IC CD4017 is a decade counter, it can be used in a variety of ways. In this programmable LED indicator circuit, it has been used to program a bicolour LED indicator in 10 different modes ...

Here’s a really fascinating circuit that implements a combination lock using relays and logic gates. Even with the schematic and written explanation of how it works we’re still left somewhat in the ...
