Using the PWM technique, the average rate of the voltage applied to the DC motor is controlled by turning on and off a very high power supply. The frequency of this switching will be in the order of tens of kilohertz. Now, the average voltage applied to the DC motor will depend on the...

I measured the PWM frequency that came from our Arduino controller and got a value of 488 Hz. This is obviously the source of the “whining” sound, and it also is the reason that the waveform is so distorted. The motor coil(s) are acting like inductors and so the output of the MD1...

How can I use this (possibly) existing PWM signal on the negative pin as an input to the control pin of the powerful fan? Edit: The powerful fan will be connected directly to the power supply, leaving it's control on the control pin. It expects a PWM signal on th...

By default the Arduino does PWM at about 500hz - way to slow for this project. If you look through the code you'll find some tweaks that boost that up to 64,000hz. Step 32: Green Laser Upgrade! Green lasers appear much brighter than red ones of the same power - and are still "...
By adjusting the value in the PR2 register, you can change the PWM frequency. Higher PR2 values will result in a lower PWM frequency, and lower PR2 values will lead to a higher PWM frequency. CCPR1L (CCP Register 1 Low): This register controls the duty cycle of the PWM signal, which...
