The Atmega 328P chip in the Arduino Uno has three PWM timers (known as Timer 0, Timer 1, and Timer 2) controlling six PWM outputs. Each of the timers has a prescaler that generates the timer clock by ...

The reason for the 0/255 check is simply that using Fast PWM you can not go to zero, when you are say using an LED under PWM, having it not go to zero is very noticeable, it’s effectively a runt ...

If you do not believe that test it yourself quickly through an Arduino and a PWM example sketch. You can clearly see a big brightness change between analogWrite(x,1) and analogWrite(x,2), but can’t ...

Good stuff, Al. Thanks. I’m a big fan of ChibiOS. I recently decided I’d do a quick survey of all the RTOSes that will run on an arduino (328P at least) and I quickly settled on ChibiOS as the ...

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 ...

An Arduino is a popular open-source single-board microcontroller. Learn how to program one and let the possibilities take shape. By The Big Book Of Hacks Published Jan 10, 2013 3:00 AM EST Get the ...

Arduino can deliver high-speed PWM For a long time I have admired the pulse-with modulators designed into Atmel (now Microchip) AVR microcontrollers . The company was early into adding phase-locked ...

The Arduino IDE provides a sample sketch with a simple program outline in a text window when you first open it. There are also a vast array of code samples under the File->Examples submenu item.
