Frequency Shift Keying Demodulator Circuit

Frequency shift keying demodulator circuit

Frequency Shift Keying (FSK) plays a significant role in the field of computer peripheral and wireless communication, facilitating the transmission of binary data or code. This technique involves the manipulation of a carrier frequency, which undergoes precise shifts between two pre-established frequencies. The utilization of FSK allows for efficient and reliable data transfer. Description of Frequency Shift Keying Demodulator Circuit An area where FSK finds particular utility is in demodulating signals, and the 565 phase-locked loop (PLL) serves as an excellent tool for FSK demodulation. In this context, a binary…

Water Flow Detection with Alert System using 555 IC

water flow detection and alert system

Sometimes we have to check the water supply pipeline from the municipal whether water is coming or not. Though the supply interval is fixed, the supply time may vary accordingly. It is quite possible to forget to switch on the motor, which results in no water in the reservoir. The article named, “Water Flow Detection with Alert System using 555 IC” is written to tackle such situations. In this article, you will learn to construct a simple water flow detector circuit. The circuit basically triggers the alarm when the water…

Calling Bell Circuit Diagram

Calling Bell Circuit Diagram

In this article, we are satisfying the curiosity of electronics hobbyists, you and I alike by making a calling bell circuit diagram. The project can be set up in different rooms of an office or hospital and the attendant or office boy waiting place or nursing station. When a call is made from any of the rooms the attendant can be notified through the bell and he/she can verify the room from which the call is made by looking at the display showing the room number. Thus this project allows…

Automatic Solder Smoke Extractor

author prototype of solder smoke extractor

Automatic Solder Smoke Extractor: Soldering is the process of joining electric/electronic components together. It is a very basic and most used process in the field of electronics because it is used to establish a secure connection between PCB and the components. Multiple types of solder wire are available at the market varying in dimensions and quality. Although there are multiple types of solder wires almost all of them are made from Lead and tin. Only the heated iron melts the wire so it is a must to let the iron…

Arduino Capacitance Meter Project

arduino capacitance meter prototype

In this project you will learn how to make your own arduino capacitance meter (measure the value of capacitor from the range of pF to 1000’s uF). Generally, electronic hobbyist love to design their own gadget rather than buy. In this project we are using two approach for capacitance measurement i.e. charging and discharging approach arduino capacitance meter and multivibrator approach arduino capacitance meter. For measuring low value capacitor, we are using charging and discharging approach and for measuring high value capacitor we are using multivibrator approach. So, before starting…
