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 ...

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 ...

If you want to add a keypad to your Arduino project, the options are pretty limited. There’s that red and blue 4×4 membrane we’ve all seen in password-protected door lock projects,… ...

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 ...

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 the problem. You can watch the video below.

This little guy, while simple in nature, acts as a fully functional (and portable) keypad on the go! It comes with two main programs, and it connects easily to your Arduino. It can be used to: 1 ...

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 ...

This circuit uses Microchip’s PIC16C71, an 8-bit microcontroller, to create a digital voltmeter with an LED display and a keypad. To view the application note, click on the URL below.
