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,… ...

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.

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 ...

Code Functionality Keypad Input: The code reads the input from a 4x4 keypad matrix. Keyboard Emulation: Based on the pressed key, the Arduino sends corresponding keystrokes to the computer. Keystroke ...

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 ...

Overview The Arduino Keypad-LCD Controller is a project that utilizes an Arduino Uno R3, an LCD display, and a keypad to create an interactive user interface. This system allows users to input data ...

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 ...

PCA9685 with Arduino Circuit Diagram We are going to connect eight servo motors to the PCA9685 controller which is eventually more than the Arduino board PWM digital pins. Also, currently, we are ...
