Hello,
I think i have a serial command problem over the TX pin.
When I use this Sketch and I press the button I get really strange outputs on my serial screan.

- Turns on and off a light emitting diode(LED) connected to digital
- pin 13, when pressing a pushbutton attached to pin 7.

*/int ledPin = 13; // choose the pin for the LED
int inputPin = 2; // choose the input pin (for a pushbutton)
int val = 0; // variable for reading the pin statusvoid setup() {
pinMode(ledPin, OUTPUT); // declare LED as output
digitalWrite(inputPin, HIGH);
pinMode(inputPin, INPUT); // declare pushbutton as input
Serial.begin(9600);
}void loop(){
val = digitalRead(inputPin); // read input value
if (val == LOW) { // check if the input is HIGH
digitalWrite(ledPin, LOW); // turn LED OFF
Serial.println("test");
} else {
digitalWrite(ledPin, HIGH); // turn LED ON
}
}
