This PWM signal can be used to apply a time indicating that something is activated, known as a duty cycle. For example, a 50% duty cycle will have the circuit load “on” for half the time.

Figure 2 Proposed PWM generator circuit This simple yet powerful circuit is extremely compact to integrate on a chip. For example, a 10MHz version of the circuit, including a driver for a 10pF ...

A circuit diagram of a driving motor using a variable DC source. When using a PWM source, the circuit sees Ohmic resistance and inductance due to frequent switching.

Another popular example, the STM32F051R8 (that's the microcontroller that some of the popular ST boards use) has 11 timers, and many of them have more than one CCP. Texas Instrument’s ARM based ...

The PWM refresh rate on these devices will rise from 240Hz to 480Hz, as reported by Android Authority. It is the same as what is found in the flagships from Apple and Samsung. It can help reduce eye ...

I present here a PWM circuit that is simple and cheap enough to be built by the casual electronics builder. Why would you want to use PWM instead of a rheostat or voltage regulator?

For example, using the same value of resistors on two PWM pins increases the resolution by one bit. Two pins with a resistor value ratio of 1:4 increases the resolution by four bits, and so on.

The obvious answer is a single few-pin microcontroller, and this is clearly possible, but getting it to work at the edge-cases is non-trivial if good resolution is the aim – to avoid over-sampling or ...

This was the motivation that led him to produce the dazzling 16 RGB LED example seen in the video after the break. His setup doesn’t use expensive LED drivers, but instead utilizes 595 shift ...
