Frequency Counter for PC - Arduino Project Hub

Changing PWM Frequency on the Arduino. 1. 1 How do you change the PWM frequency? 1. 2 For Arduino Uno, Nano, YourDuino RoboRED, Mini Driver, Lilly Pad and any other board using ATmega 8, 168 or 328; 1. 3 For Arduino Mega1280, Mega2560, MegaADK, Spider or any other board using ATmega1280 or ATmega2560


Arduino Uno is a microcontroller board based on the ATmega328P (). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button.

Frequency counter using arduino 40KHz

The Arduino Nano uses the ATMega328P microcontroller, same as the Arduino Uno. Pin 11's PWM is controlled by Timer 2. By default Timer 2 has a prescale of 64 (ie. setting 0x04). The base frequency of Timer 2 is 31372. 55 Hz resulting in a frequency of 490. 2 Hz (ie. 31372. 55/64 = 490. 1961).

OR how to generate a variable frequency PWM signal using Arduino Uno? Arduino uno board contains an atmel Atmega328 microcontroller on it. I am going to generate a PWM of 50% duty cycle on frequencies between 10Hz to 100Hz. Frequency is changed using a potetiometer/variable resistor connected to an analog pin of the Arduino.

Frequency Counting Using Arduino Arduino Frequency Counter

Home How to modify the PWM frequency on the arduino-part1(fast PWM and Timer 0) The default frequency of arduino PWM pins is around 490Hz for 9, 10, 3,11 and around 980 HZ for 5, 6, but for many applications we need some higher frequencies. The arduino uno can generate frequencies for PWM pins up to 8Mhz. To modify these values
