I want to open the notepad and with a push button connected to the arduino to press ENTER and change line. I have also connected an LED as an indicator for the push button. The problem is that sometimes it either changes line automatically or not at all.... the button never works....
const int buttonPin = 7; // the number of the pushbutton pin
const int ledPin = 13; // the number of the LED pin
// variables will change:
int buttonState = 0; // variable for reading the pushbutton status
void setup() {
// initialize the LED pin as an output:
pinMode(ledPin, OUTPUT);
// initialize the pushbutton pin as an input:
pinMode(buttonPin, INPUT);
Serial.begin(9600);
Serial.println("#S|NOTEPAD|[]#");
}
void loop(){
// read the state of the pushbutton value:
buttonState = digitalRead(buttonPin);
// check if the pushbutton is pressed.
// if it is, the buttonState is HIGH:
if (buttonState == HIGH) {
// turn LED on:
digitalWrite(ledPin, LOW);
Serial.println("#S|SENDK|[0&{ENTER}]#");
}
else {
// turn LED off:
digitalWrite(ledPin, HIGH);
}
}
