Touch Switch Module
The touch switch module requires 4 pins to connected to the Arduino board as input and 2 pins for Vcc and Gnd.
The touch sensor module has 4 sensor pads with LED diode that shows whether sensor pad is touched.
Each touch sensor pad has its own value as below:The following code will show the touched pad value (1, 2, 3 or 4).
You can also try touching multiple pads at the same time.
bool switch1 = false;
bool switch2 = false;
bool switch3 = false;
bool switch4 = false;
void setup()
{
Serial.begin(9600);

}

{
getSwitchSettings();
Serial.print("Switches On:");
if(switch1) Serial.print(" 1");
if(switch2) Serial.print(" 2");
if(switch3) Serial.print(" 3");
if(switch4) Serial.print(" 4");
Serial.println();
