What is the PWM frequency of Arduino?
Description
| Board | PWM Pins | PWM Frequency |
|---|---|---|
| Uno, Nano, Mini | 3, 5, 6, 9, 10, 11 | 490 Hz (pins 5 and 6: 980 Hz) |
| Mega | 2 – 13, 44 – 46 | 490 Hz (pins 4 and 13: 980 Hz) |
| Leonardo, Micro, Yún | 3, 5, 6, 9, 10, 11, 13 | 490 Hz (pins 3 and 11: 980 Hz) |
| Uno WiFi Rev2, Nano Every | 3, 5, 6, 9, 10 | 976 Hz |
How does PWM work on Arduino?
PWM has several uses:
- Dimming an LED.
- Providing an analog output; if the digital output is filtered, it will provide an analog voltage between 0% and 100%.
- Generating audio signals.
- Providing variable speed control for motors.
- Generating a modulated signal, for example to drive an infrared LED for a remote control.
Does Arduino Nano have PWM?
Nano has 6 PWM pins, just like an Uno. 3,5,6,9,10,11. CrossRoads: Nano has 6 PWM pins, just like an Uno.
Why PWM pins are used in Arduino?
It is available in the File->Sketchbook->Examples->Analog menu of the Arduino software. Pulse Width Modulation, or PWM, is a technique for getting analog results with digital means. Digital control is used to create a square wave, a signal switched between on and off.
Why do we need PWM?
PWM is used in many applications, ranging from communications to power control and conversion. For example, the PWM is commonly used to control the speed of electric motors, the brightness of lights, in ultrasonic cleaning applications, and many more.
Why we use PWM pins in Arduino?
What is PWM. PWM stands for Pulse Width Modulation and it is a technique used in controlling the brightness of LED, speed control of DC motor, controlling a servo motor or where you have to get analog output with digital means.
