Abstract: Mobile Phone Controlled Electrical Home Appliances is One kind of home automation.Because it is the technological advancement that can lead to higher study of living. Sometimes unfortunately we may forget switch off the appliances while going to the outside and we face the problems to switch off these devices when we are out of home. To solve these types of problems this article explains us how to design a simple circuit, which will on the devices remotely and devices will off automatically after the specified time interval. Till now we have seen so many home automation projects that control the devices or appliances from the remote place but the main advantage of this circuit is simple because we are not using any micro controller in this circuit and it uses the components which are easily available in the market.It can be helpful for upcoming advanced technology instead of using GSM Module Or something like costly products.

Abstract: We live in an electric age where the world is connected for every person, without the need of being actually connected with the help of wires. Messages, information, and signals are sent from one part of the world to the other within minutes and seconds. All of this is possible only with the help of signals from one device to the other from one location to another one, miles away and the quantity and dependence on these signals and their interconversions are humungous.That’s why modulation is needed. AM is still widely used for commercial broadcasting on the long,medium and short wave bands because the radio receivers capable of demodulating amplitude modulation are cheap and simple to measure.The atmospheric signals like lightening and man madeelectrical signals affect this transmission. The main advantage of this circuit is simple because we are not using any microcontroller in this circuit and it uses the components which are easily available in the market.It can be helpful for upcoming advanced technology instead of using GSM Module Or something like costly products.

An ultrasonic sensor is an instrument that measures the distance to an object using ultrasonic sound waves. An ultrasonic sensor uses a transducer to send and receive ultrasonic pulses that relay back information about an object’s proximity. High-frequency sound waves reflect from boundaries to produce distinct echo patterns.

Abstract: Chat refers to the process of communicating, interacting and/or exchanging messages over the Internet. It involves two or more individuals that communicate through a chat-enabled service or software. Chat is also known as chatting, online chat or Internet chat. There are three commonly used types of chat. They are Instant Messaging, ICQ, and IRC. Instant Messaging. Instant messaging (IM) is one of the most popular forms of chat. Most of the time, instant messaging (IM'ing) is just between two people, although most IM software can handle group chats (with 3 or more people.) Here ,the Chat engine is made based one the subscribe and publish concept using PyQt5 Framework on PyCharm.
