I wrote this when I could not find Arduino code online that could accurately and reliably read 25kHz pwm signals. For reliable PWM you must handle the following edge cases: 100% or 0% PWM signal with ...

For the “common” PWM, if we write a value from 0 to 255 on a PWM pin, the Arduino library will drive the assigned pin to output a PWM signal whose on time is in proportion to the written value.

A few months ago, [Julian Ilett] found a problem using the Arduino library for PWM. Recently, he revisited the issue and used his own PWM code to fix ... counter used to generate the PWM signal.

Output Up To 768 PWM Signals From One Arduino. 46 Comments . by: Mike Szczys. July 20, ... (which was running out of memory fast with all the pwm code) ... You can use the PWM signal for anything.

In this example, we will control the brightness of an LED using Pulse Width Modulation (PWM) in python on Arduino. The LED is connected to digital pin 5 of the Arduino, which is capable of PWM output.

Arduino Gemma from Adafruit is also based on the ATtiny85, and PB0 and PB1 appear to be accessible. This board has a USB connector for programming and a voltage regulator. This board, which I am ...

Sorry if this it the wrong place to ask questions but I'm desperate, and Susan you seem to be one of the few that knows the R4. I've tried to read your code on attaching interrupts to R4 events but it ...

The machine uses a ‘grbl’ controller, which has an Arduino-based circuit that includes multiple outputs, including a powerful 24V pwm signal that is generally used to drive a 60-80W spindle motor..
