I have a simple capacitive touchy feely lamp and want to up the voltage?

At the moment I have 2 LEDs and 2 pieces of tin foil as the sensors. I understand I need a relay but I don’t know how to wire it up nor change my original code.

This is my code at the moment:

#include <CapacitiveSensor.h>

CapacitiveSensor capSensor2 = CapacitiveSensor(4,2);
CapacitiveSensor capSensor6 = CapacitiveSensor(4,6);

int threshold = 1000;
const int ledPin12 = 12;
const int ledPin10 = 10;

void setup() {
Serial.begin(9600);
pinMode(ledPin12, OUTPUT);
pinMode(ledPin10, OUTPUT);
}
void loop() {
long sensorValue2 = capSensor2.capacitiveSensor(30);
long sensorValue6 = capSensor6.capacitiveSensor(30);

Serial.println(“Sensor2=”);
Serial.print("\t");
Serial.println(sensorValue2);

CheckSensor (sensorValue2, ledPin12);
CheckSensor (sensorValue6, ledPin10);

delay(10);
}

void CheckSensor (long sensVal, int ledPin){
if(sensVal > threshold) {
digitalWrite(ledPin, HIGH);
}
else{
digitalWrite(ledPin, LOW);
}
}

You want to switch a lamp with more power & brightness than the LEDs? How much voltage, current, Watts?

I am going to use two stage lights at UK mains 230v and they are both 500 watts.
Thanks.

I would use Solid State Relays: http://www.mouser.com/Electromechanical/Relays/Solid-State-Relays/Solid-State-Relays-Industrial-Mount/_/N-ay0tw http://www.mouser.com/Electromechanical/Relays/Solid-State-Relays/Solid-State-Relays-PCB-Mount/_/N-ay0uc?P=1z0x3sdZ1z0x1epZ1z0x2pxZ1yzrt3uZ1z0x35lZ1yztgtcZ1z0x121Z1z0x123Z1yzvdq0Z1z0x11yZ1z0x122Z1z0t3h1Z1z0x11qZ1yzu4hlZ1z0x124
