This is the smart coin based mobile charging system that charges your mobile for particular amount of time on inserting a coin. The system is to be used by shop owners, public places like railway stations to provide mobile charging facility. So the system consists of a coin recognition module that recognizes valid coins and then signals the microcontroller for further action. If a valid coin is found it signals the microcontroller and microcontroller then starts the mobile charging mechanism providing a 5V supply through a power supply section ....etc

Here we put forward a fully automated coin based water dispenser system using microcontroller and sensor. The system is capable of fully automated water/cola dispensing using motors and sensors. The system also senses if glass is placed at the counter to avoid water spoilage if there is no glass placed at the counter panel. The system uses IR sensors to detect presence of glass and then the sensors send a signal to the microcontroller. The microcontroller now processes the information sent by the sensors to determine if glass is present. The sy ....etc

wireless communication is limited to certain range because there are some obstacles and communication barriers across the way. so the receiver is not able to receive the signal as it is sent from the transmitter. so we need the help of satellite.

here we are designing a satellite which receives signal from one station. it amplifies and re transmits the signal to the other station. both the transmitter and receiver uses telescopic antenna for transmission and reception.

in this section, a signal is transmitted using fm transmit ....etc

Abstract

Filling is a task carried out by a machine that packages liquid products such as cold drinks or water. Traditional methods of bottle filling involved placing bottles onto a conveyor and filling only one bottle at a time. This method is time consuming and expensive.

Our paper aims at filling and capping bottles simultaneously. The filling and capping operation takes place in a synchronized manner. It also includes a user-defined volume selection menu through which the user can input the desired volume to be filled in the bottles. The ....etc
