After all, few of us can create our own wire, our own transistors, or our own integrated circuits. A few months ago, [Julian Ilett] found a problem using the Arduino library for PWM.

PWM pins work the same way across all Arduino boards, so you don't need to go out of your way to buy a Mega if you already have a board supporting PWM. On the Uno, Nano, and Mini, the PWM pins are ...

Here is an Arduino based circuit with three independent pulse width modulated (PWM) channels to fulfil your requirements! Just follow the schematic diagram to complete the construction, and use any ...

Tiny basic PWM The ATtiny85 microcontroller allows us to generate an analog output using PWM. The ATtiny85 microcontroller has two timers that can be used to generate PWM signals. The first is Timer 0 ...

To build the system, [Patrick] has chosen an Arduino Duemillenova, an RTC, a small LCD screen, some cheap LEDs from eBay and a handful of N-channel NPN transistors to provide the PWM for the LEDs.

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 ...

Arduino offers a simple framework to programme some AVRs in something like C but, without extra work, only allows PWMs to work at under 1kHz. The AVR used in the Arduino Leonardo and Micro is the ...
