TOUCH UP PART FOR PRESENTATION (Hardware)

The project started with a solder jumper wires from the LCD to the circuit. Then, some soldering recipients. Receiver mounted on the circuit. In addition, the LCD mounted on a clear acrylic sheet so everyone can read the output.

Keypad Detector Layout

This product is designed to detect any keypad handphone number from 0 to 9, of course ( * #). Just press any keypad number from all handphone than data in binary code will transmit to reciever module (i used 315MHz RF module with address code).
