Arduino PWM As you may know, two PWM outputs of Arduino Uno are linked to the timers. For the “common” PWM, if we write a value from 0 to 255 on a PWM pin, the Arduino library will drive the assigned ...

There is a certain default frequency for each PWM pin, which is called when the analogWrite command is used on that pin. This default frequency can be changed to a value as high as 65Khz and as low as ...

The Arduino library authors elected to detect that edge case and just force the output pin to go low in that case. When inverted, however, the pin still goes low when it ought to go high.

It allows each motor to have a current rating of 2 A. However, heat sinks are required at these currents. Speed control We can use an Arduino board to generate a pulse width modulation (PWM) signal ...

I have been discussing control algorithms for a power supply and idly looking for some easy hardware on which to try the technique – hardware small enough to build into a prototype. See also: An AVR ...

The Arduino IDE has to use one of its timers in fast PWM mode (timer 0) and fudges the 0% setting with a trick: by detecting the ‘0’ command, which the hardware would convert to its 1/256 setting, in ...

Why is only Pin D0 and D1 marked as PWM pins in the pins_arduino.h file? As far as I can read from the datasheet, these ATtinys have PWM capabilities on 4 pins.

Community collaboration is a great thing. Take the Arduino PWM library for shift registers. Some folks at the Arduino forum pitched in and helped [Elco] trim off a bunch of clock cycles by using th… ...
