KY-036 - Metall-Berührungssensor

 

Einführung

Metal Touch Interface module and number 13 comes with LED build a simple circuit to produce a touch cue lights 13 comes with digital interfaces of the LED, the metal touch sensor connected digital three interfaces, when a metal touch Sensor senses a key signal, LED ights, otherwise off.

Beispielcode

int Led = 13 ;/ / define LED Interface
int buttonpin = 3; / / define Metal Touch Sensor Interface
int val ;/ / define numeric variables val
void setup ()
{
pinMode (Led, OUTPUT) ;/ / define LED as output interface
pinMode (buttonpin, INPUT) ;/ / define metal touch sensor output interface
}
void loop ()
{
val = digitalRead (buttonpin) ;/ / digital interface will be assigned a value of 3 to read val
if (val == HIGH) / / When the metal touch sensor detects a signal, LED flashes
{
digitalWrite (Led, HIGH);
}
else
{
digitalWrite (Led, LOW);
}
}
