Mais informação

  • The module is based on a touch-sensing IC  (TTP223B) capacitive touch switch module. In the normal state, the module output  low, low power consumption; When a finger touches the corresponding position,  the module output high, if not touched for 12 seconds, switch to low-power mode.

  • Jog type : the initial state is low , high  touch , do not touch is low ( similar touch of a button feature )

  • Module can be installed in such as surface  plastic, glass of non-metallic materials

  • In addition to the thin paper ( non-metallic )  covering the surface of the module , as long as the correct location of the  touch , you can make hidden in the walls, desktops and other parts of buttons

Arduino Capacitive Touch Sensor Tutorial

 

Code:

// Henry's Bench
// Capacitive Touch Sensor Tutorial
 
// When Sig Output is high, touch sensor is being pressed
#define ctsPin 2 // Pin for capactitive touch sensor
 
int ledPin = 13; // pin for the LED
 
void setup() {
  Serial.begin(9600);
  pinMode(ledPin, OUTPUT);  
  pinMode(ctsPin, INPUT);
}
 
void loop() {
  int ctsValue = digitalRead(ctsPin);
  if (ctsValue == HIGH){
    digitalWrite(ledPin, HIGH);
    Serial.println("TOUCHED");
  }
  else{
    digitalWrite(ledPin,LOW);
    Serial.println("not touched");
  } 
  delay(500);
  
}
