void setup() {
  pinMode(A0, OUTPUT); //A0 DAC pin to output
  analogWriteResolution(10); //default DAC resolution is 8 bit, swith it to 10 bit (max)
}

void loop() {
  //create pulsed current profile
  analogWrite(A0, 16); //Set DAC to approximately 10mV --> current 10mV / 5ohm = 2 mA
  delay(500);
  analogWrite(A0,310); //Set DAC to 1V --> current 1V / 5ohm = 200 mA
  delay(50);
