Electronics Project on Coin Based Mobile Charger

This Electronics engineering project report on "coin based mobile charger". The main aim of this thesis is to charge your mobile phone in public through the use of the machine in which you can insert the coin and charge your mobile phone. This project is very useful to people who are all using the mobile phone without charging condition in the public places. You can also Subscribe to FINAL YEAR PROJECT'S by Email for more such projects and seminar.

This project is the little bit similar to the project "coin based water controlling system", which we posted few days back. The project on coin based mobile phone charger is very useful to that person for using the coin to charge for that mobile. The IR (infrared) transmitter is used to transmit IR signal on the transmitter side.


The IR receiver is used to receive the IR signal on the receiver side. Between the IR transmitter and receiver, insert a coin to change the polarity of the pulse in signal conditioning unit (SCU) input.


The SCU is used to convert the low pulse to high pulse and that pulse is inverted by the inverter. The 555 IC acts as a timer to produces the high pulse for particular time period. Again the SCU is used to converting low pulse to high pulse and this output is given to the input of driver circuit. The driver circuit is used for providing the sufficient input voltage of relay. The relay will on to activate the 230v charger, we will use the charger to charge for our mobile phone.


This project report on "coin based mobile charger" includes block diagram, working, circuit diagram, etc. Please use this project report for your reference and study work.
