## analogWrite()

#### Description

Writes an analog value as PWM to the specified port on the robot. The board has a 8-bit PWM, allowing for 256 discrete levels.

Robot.analogWrite() only works on TKD4, located on the Control Board. It cannot be used at the same time as TK0 through TK7.

#### Syntax

Robot.analogWrite(port, value)

#### Parameters

port: TKD4

value : 0 to 255

#### Returns

none

#### Examples

#include <ArduinoRobot.h>
void setup(){
Robot.begin();
Serial.begin(9600);
}
void loop(){
for(int x=0;x<256;x++){
Robot.analogWrite(TKD4, x); //increase brightness of an LED on TK0
delay(20);
}
}
