Simple test code:
// Definujte pin, ku ktorému je pripojený dotykový senzor
const int touchPin = A0;
void setup() {
// Nastavený sériový port pre komunikáciu s počítačom
Serial.begin(9600);
}
void loop() {
// Hodnota dotykového senzora
int touchValue = analogRead(touchPin);
// Hodnota dotykového senzora do sériového monitora
Serial.println(touchValue);
// Ak je hodnota dotykového senzora väčšia ako 500, vypíše správu "Dotyk zistený"
if (touchValue > 500) {
Serial.println("Dotyk zistený");
}
}
