The project aims to create a PWM controller that contains a frequency range from about 170 to 200Hz to achieve a pulse width regulation featuring almost 0-100% with a relatively stable oscillator ...

Simply adding a diode and potentiometer to a 555 timer operating in the asynchronous mode yields a pulsewidth modulator (PWM) with a duty factor adjustable from 1% to 99% (Fig. 1). Applications would ...

Used in a variety of timer, pulse generation, and oscillator applications, the 555 was designed in 1971 by Hans Camenzind. A favorite for many engineers, the 555 is still in widespread use due to its ...

That’s stupid! Why use a bunch of parts when you can use an Arduino? However, we rarely see those two comments on the same post. Until now. [ZHut] managed to bring these two worlds together by ...

Hans Camenzind, the designer of the popular 555 timer IC died this week in Silicon Valley. He was 78. My condolences to his family and friends. Hans came to the U.S. from Switzerland in 1960. He ...
