Hii everybody,,

I want to build a LCD based sound operated display using 8051 microcontroller (AT89C51) Project Code: MC038  but the output in the LCD should be wireless. I want to attach LCD in a remote in which it will show the message and the sensor will be attached to a robot.

 for this u can connect sensor output to micro-controller which send the signal to another micro-controller through RF module which further display message on lcd.
