This circuit enables the on/off times of a 555 timer to be independently varied over a wide range. This is not possible with a conventional 555 circuit with the RC network being charged from the ...

Here this circuit is based on the principle of audio amplification using operational amplifier and pulse width modulation using 555 Timer. In this article we are describing the principle, design and ...

Over on YouTube [Andrew Neal] has a Function Generator Build for Beginners. As beginner videos go this one is fairly comprehensive. [Andrew] shows us how to build a square-wave generator on a ...

This file type includes high-resolution graphics and schematics when applicable. Paul Rako, Creative Director, Rako Studios Back in 2011, Jeff Hamilton contacted Bob Pease, asking for Bob’s experience ...

Like many of us [AnotherMaker] is a fan of the classic Forrest Mims electronics books, specifically, the Engineer’s Mini-Notebook series. They were great sources of inspiration, but at the time, he ...

The 555 timer IC is an integrated circuit (chip) which is used in a variety of timer, delay, pulse generation, and oscillator applications. 555 Signals and Pinout (8 pin DIP) Figure below shows the ...
