Solderable DIY kit with
"Assembled & Tested Prototype board"

DIY kit comes with an Assembled and Tested prototype board and pre-programmed controller ensuring 100% output guarantee. Includes complete hardware & tools with plain PCB for assembling project from scratch.

Extensive documentation for project execution including step-by-step instructions for Circuit building, Assembly procedure and Troubleshooting. Thorough understanding from the Problem definition to Circuit Design to Programming, Simulation, Testing, Troubleshooting and finally building a working Hardware Prototype.

400+ end to end unique project solutions in wide areas of Electronics, Electrical, Embedded, Communication, IoT, Arduino and more.


The main objective of this project is to intimate the concerned authorities about an unauthorized access of secured areas such as museums, residential houses, banks etc. As crime rate is on the rise and burglars are getting smarter, the security system for banks, shops and houses needs to be full proof.

This proposed system ensures that at any moment if any unauthorized person tries to open the bank locker; a telephone number will be dialed through the telephone line connected to it.

This project uses a microcontroller from 8051 family. An external memory EEPROM is interfaced to the microcontroller to store the contact number to which the call is to be made. The arrangement is made in such a way that when someone tries to open the door forcefully even when it is locked the microcontroller gets an interrupt through a hidden switch mechanism interfaced to it.

Microcontroller will automatically dial to the number which is stored in the EEPROM through DTMF encoder interfaced to it. Microcontroller fetches information from external memory like EEPROM using I2C (Inter IC communication) protocol.

Further this project can be enhanced to use a cell phone or GSM modem with a serial camera connected to it. The camera will take photographs and sends it over MMS/ email attachment to the concerned authorities.

I come to know about Edgefx by Google. I used projects as a keyword in google to find Edgefx.I decided by examine the fully functioned kit available with Edgefx. I like the working and packing.Yes the kit delivered on time with the right components.No I purchased through online.You need to implement complex based projects.
