hi i'm a real novice to electonics but find it very amazing. I really need help building a circuit, you will probably find it very simple. i'm based in the u.k. running from a 9v battery, a need a circuit that has 6 micro switches and a light sensing diode ( the round one that when light hits it, current can flow). when any of these are activated, a relay is switched and stays active setting off a siren untill the power is turned off, the light sensing thingi must be very sensative. The last thing is when the siren sounds a electric shock(buzz) like a joke stun type shock is given to the person holding the wires. many thanks to anybody responding.
