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 ...

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 ...

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 ...

I've added code that converts PPM signals to PWM signals to the New GLDAB by Arduino. New GLDAB by Arduino modified to receive ppm signal from RX and output PWM signal. This allows you to use a small ...

Once you have set up the circuit, connect the Arduino to your computer using a USB cable. Now, let's move on to the coding section. We'll break down the essential parts of the code to understand how ...

Back in 2011, Elektor presented a DIY 50-m range directive sound beam using an array of piezo ultrasonic transducers (up to 200) driven with a PWM signal. While the ultrasonic directive speaker ...

Community collaboration is a great thing. Take the Arduino PWM library for shift registers. Some folks at the Arduino forum pitched in and helped [Elco] trim off a bunch of clock cycles by using th… ...

The PWM’s timebase is 1 kHz, so component values must accommodate that frequency. If you need other frequencies, you must calculate new component values using the following equation: C=1/(10×F×R), ...

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 ...
