In this kit pay and use power system using coin sensor, we have tried to reduce the wastage of electrical power which often arises due to negligence of the user. Here we have to make a power system in such a way that, the user can use it only for a limited period of time after paying for it. A precise coin acceptor is there to accept the coin, and it generates the power only after the proper amount of coin (as defined by the user) is inserted. For each unit of price, the power is available only for a limited period. The time left for usage will be shown on the LCD continuously.
In the kit pay and use power system using coin sensor, there is a coin acceptor which can be calibrated by the user by inserting a standard coin to it. The microcontroller can sense the number of the standard coin inserted by the user, hence can calculate the time window for that particular user. There is a dot-matrix LCD that displays the time remaining for the user. A relay is there to control the power, which is interfaced with the microcontroller. If the time period gets elapsed the microcontroller turns off the relay, hence the power gets disconnected.

Right & Best place for embedded systems projects in India'
I needed a project to submit and my problem is solved after this.Excelllent working project even they are very helpful whenever u need any info about the project or if u want to know the working of project.
works as mentioned however it would have been better had there been some steps needed from students like some basic assembling etc. Otherwise it worked perfectly fine.
Good and fast answer reply , not expensive services and good quality overall.
Help desk team stays with you and make sure that everything is working for your project till the end , and offers assistance for any questions after. I can say that my debugging engineer was brilliant.
