The circuit presented here can be-used as a lock for important elecÃ‚Â¬tronic/electrical appliances. When card is inserted inside its mechanism, depending upon the position of punched hole on the card, a particular appliance would be switched on. The card is inserted just like a floppy disk inside the disk drive. This card should be rectangular in shape with only one punched hole on it. T7 o The circuit uses eight photo-transistors (T1 through T8). When there is no card in the lock, light from incanÃ‚Â¬descent lamp L1 (40-watt, 230V)..............etc [:=Read Full Message Here=:]
