#2 Arduino AnalogWrite Explained

 Hi everyone, I'm your Manitesla.In the last post, we learned how to turn Arduino pins on and off with the Arduino digitalWrite command. This command is best if you only want 0 or 5 volts. In this post, I'll show how you can get the in-between values (0-5)by using the analogWrite command. In the upcoming post, I will in detail how analogWrite works, but this present post  gets you started, and shows you how to control the brightness of an LED. U can watch the video below to learn how to control led brightness. 

               

Arduino AnalogWrite Code:

int ledPin = 9; // LED is connected to pin 9th pin 
void setup() {
  pinMode(ledPin, OUTPUT); // sets the pin as output
}

void loop() {
analogWrite(ledPin, 255);//analogWrite values from 0 to 255
}
