sure. Just post what you've got so far and we'll point you in the right direction. You'll need to include the code you have so far and probably the hardware schematic so we can see how it interfaces etc.

Maybe he took to much Obay in college.

Sorry - bad joke about his username.

@Obaid123:

It would be best for all of us if you showed us what you have done so far. At least how you think this can be done...

am using PIC16F877a microcontroller.. am using Two IR receiver and transmitter. i have started writing program.but the thing is that how am i gona write in program that if there is any change in the outputvoltage of the receiver show 1 on the LCD screen???

and one more thing, when there is transmission between reeiver and transmitter, the o/p V is 4.65, and there is obstruction in the transmission, it gives me rise of 5mV means 4.7V. will the microcontroller sense that 5mV change???
