Here is a circuit that will output a PWM wave good for varying the speed of a DC motor. Why is this not going to work? How would you fix it? The 555 timer can’t handle that type of load, and it is not ...
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 ...
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 ...
