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 ...

The 555 timer IC is a handful of active components all baked into one beautifully useful 8 pin package. Originally designed for timing purposes, they became ubiquitous parts that can achieve almost ...

“HW-687 is one easy module for adding speed regulation to your next DC motor-based project. It is a simple pulse-width–modulated speed controller providing smooth control with almost no jerks. There ...
