The circuit was designed to be used as flashing eyes in Halloween gadgets with the addition of rhythmic music or speech while being powered by 3 V battery.
The objective of the circuit is to be able to provide a night lamp with an ultra low current consumption from a battery source in case of the absence of wall mains socket.
The circuit was constructed to provide a time delay feature when switching OFF a light to give the person enough time to reach the bed before the lamp completely turns OFF.
This simple circuit has been designed to generate sine waves with a frequency of 1 KHz while featuring low distortion and low output impedance until 1 V RMS as it obtains power from batteries.
The circuit was made in a modular design to provide a sequential illumination of LEDs or lamps as it forms a ring structure which make the circuit limitless to the number of modules desired.
The circuit was designed to provide an indication of an environment or room noise that exceeds a fixed threshold through the use of a flashing LED.
