Hi,
I connected a button to my digital input (I tried multiple digital input ports).
And I used one of the example programs (button), that i modified a bit so i could read the buttonState.
When opening the serial monitor it gave something like this "000000111111110000111000111" whitout even touching the button.
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 voor het uitlezen van de schakelaar
}
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, HIGH);
}
else {
// turn LED off:
digitalWrite(ledPin, LOW);
}
Serial.print (buttonState);
}
So that is the code i used.
Can anyone help with this?
thx
