💡 FAQ

Q: What is pulse width modulation? A: Pulse width modulation is a technique that involves pulsing the power supply on and off at a certain frequency and pulse width to control electronic devices.

Q: What are the applications of pulse width modulation? A: Pulse width modulation can be used to control the brightness of lighting, the speed of motors, and create efficient power supplies.

Q: Can pulse width modulation be used for larger loads? A: Yes, pulse width modulation can be applied to larger loads, such as high-power motors, by using transistors and sending a digital pulse width signal.

Q: How does pulse width modulation work? A: Pulse width modulation works by varying the width of the pulses sent to the electronic device. The device is on for a certain percentage of time (duty cycle) and off for the remaining percentage.

Q: Can Arduino microcontrollers implement pulse width modulation? A: Yes, Arduino microcontrollers are commonly used to implement pulse width modulation, allowing for easy control and experimentation with electronic devices.
