Pulse Width Modulation is a way to control the production of voltages. The hardware that is being used here is a BV4237:

* http://www.byvac.com/bv/bv4237.htm

The below given code sample is based on the code presented by the BB user '''wilkosoft''':

* http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1252352897/0

#include <Wire.h>

#define dac 0x31

void sw16set(byte val) {
Wire.beginTransmission(dac); // join I2C, talk to BV4206 by id
Wire.send(0x16); //tell it what pin you want
Wire.send(val); //the state of the pin, from 0-8 (PWM controls the levels)
Wire.endTransmission(); // leave I2C bus
delay(100) ;
}

void setup()
{
Wire.begin();
Serial.begin(9600);
}

void loop()
{
for (byte i=0; i<9; i++) {
sw16set(i);
}
}
