I made an alarm using LDR(light dependent register). The alarm work depending on the light intensity, when light intensity will low then the alarm will rise up and when the light intensity will high then it remain off. My problem is that the buzzer is not playing continuously when the intensity is low. I need a continue beep and a reset button to reset the device and also the alarm. | |||

This circuit uses a thin piezoelectric sensor to sense the vibrations generated by knocking on a surface; eg, a door or table. Basically, it amplifies and processes the signal from the sensor and sounds an alarm for a preset period. In operation, the piezoelectric sensor converts mechanical vibration into an electrical signal. This sensor can be attached to a door, a cash box, cupboard, etc using adhesive. A 1-1.5m long shielded cable can then be connected between the sensor plate and the input of the circuit. The signal generated by the sensor ....etc | |||
