Arduino serial transmission problem

ad a delay in there so it doesnt loop so fast :slight_smile:

void setup() {
  Serial.begin(115200); 
}
void loop() 
{
  Serial.println(analogRead(A1));
delay(10);
}

upload the code. open the serial monitor (make sure you have the right COM port) and the Arduino will auto reset when you open serial monitor so it should go.
