How to Drive MOSFET with ARDUINO

This is example how to drive Mosfet using arduino, port to drive is port 9 as PWM can send data from 0 to 255 as analog voltage from 0 to 5V. Video example at : https://youtu.be/-zfrnw4Iwpg /*

Fading

This example shows how to fade an LED using the analogWrite() function.

The circuit:

int ledPin = 9; // LED connected to digital pin 9

void setup() {

// nothing happens in setup

}

void loop() {

// fade in from min to max in increments of 5 points:

for (int fadeValue = 0 ; fadeValue <= 255; fadeValue += 5) {

// sets the value (range from 0 to 255):

analogWrite(ledPin, fadeValue);

// wait for 30 milliseconds to see the dimming effect

delay(30);

}

// fade out from max to min in increments of 5 points:

for (int fadeValue = 255 ; fadeValue >= 0; fadeValue -= 5) {

// sets the value (range from 0 to 255):

analogWrite(ledPin, fadeValue);

// wait for 30 milliseconds to see the dimming effect

delay(30);
