Adjustable Voltage Regulator

These circuits were made using two common adjustable voltage regulators - the LM317T and the AMS1117ADJ. The LM317T is an adjustable voltage linear regulator that is very popular. It was invented in 1970 and is still used today. This is very …

5V Voltage Regulator

These circuits were made using four very common voltage regulators - the LM7805, the LM2940, the LM1117 and the AMS1117. The LM7805 is a linear voltage regulator that is very popular, because to put it to work no more components are …

555 Simple Sequencer

This circuit serves as the basis for a huge set of circuits ranging from led chasers, Knight Rider, Electronic Roulette, Semaphores, etc. Let’s present here two of this kind of circuits. The 555 IC is well known for being …

2 Transistor LED Flasher

Building of two circuits that flash alternately to two LEDs at a fixed cadence. These are very basic circuits and they show two ways of building circuits using transistors BJT PNP and NPN. These are classic circuits that use the …
