Switch exercise
I hacked into a wireless light switch from As Seen on TV, and controlled it with Arduino
Construction:
Switch –> Arduino –> Relay –> Wireless Light Switch (parent)
Wireless Light Switch (child) –> Christmas Lights
Arduino code:
————————————————————————————–
int ledPin = 13; //relay-control pin
int inPin = 2; //read-in pin
int val = 0;
void setup()
{
pinMode(ledPin, OUTPUT);
pinMode(inPin, INPUT);
}
void loop()
{
val = digitalRead(inPin); //read pin 7
delay(100);
if (val == 0) //if pressed -> randomized flahing
{
digitalWrite(ledPin, HIGH); //Light On
int TIME = random(50, 300);
delay(TIME);
digitalWrite(ledPin, LOW); //Light Off
}
else
{
digitalWrite(ledPin, LOW); //Light Off
}
}
