Lab-Serial(1)
Send Serial Output
Connect a potentiometer to the circuit and upload the following code to arduino.
int analogPin = 0;
int analogValue = 0;
void setup()
{
// start serial port at 9600 bps:
Serial.begin(9600);
}
void loop()
{
// read analog input, divide by 4 to make the range 0-255:
analogValue = analogRead(analogPin);
analogValue = analogValue / 4;
Serial.print(analogValue, BYTE);
// pause for 10 milliseconds:
delay(10);
}
And then open the serial monitor, you can see these random characters scroll by in the serial monitor window.
