The main aim of the Day and Night Indicator project is to help us to turn on the lights as the night falls automatically and as the dawn sets in the Day and Night Indicator automatically gets switches off the light and plays a musical morning wake up alarm. Another feature of the project is that at the time of no light in the room during night the night lamp gets turned on automatically. With the help of this circuit you are not required to switch on or off the lights in nights or in the morning. 

RPM counters are used to measure Speed of Motors (AC/DC) or any Rotating Object. They measures and indicates current Rotating Speed of Motor. They are very essential in applications like Speed Control of Motors and close Loop Control System. Such industrial RPM counters are very accurate made up of microcontroller or microprocessor.

FSK means Frequency Shift Keying. It’s one of the Modulation Scheme used to Transmit Digital Data using High Frequency carrier signal. In this Modulation Scheme bit 1 is transmitted using one carrier signal and bit 0 is transmitted using another carrier signal like

·         Bit 1 (logic high) is Transmitted using Carrier Frequency Fc1

·         Bit 0 (logic low) is Transmitted using Carrier Frequency Fc2

It means Series of bits (bit stream) are transmitted with two different carrier signals used for bit 1 and bit 0.
