Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

One way around the problem of getting a fast response from a microcontroller is to move the problem away from the processor. In the case of the ESP32 there are some built-in devices that can use GPIO ...

Many applications using miniature brushed DC motors require motors to operate at more than one load point or through specific load cycles. Running a motor at usable load points requires a variable, ...

Pulse width modulation (PWM) control, which uses variable-width digital pulses to represent the amplitude of an analog waveform, has been around for decades. The first specialized PWM IC dates back to ...

What sorts of things do you use PWM for? There are lots of very clever uses for PWM. However, there are two applications which account for most PWM applications - voltage or power modulation and ...
