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 ...

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 ...

Pulse width modulators are a fundamental building block. Among other things, they are used for remote sensing, DC motor control, and switch-mode power supply controllers. This circuit uses a ...
