have a little problem with the circuit
i followed the hardware page and patch up the circuit,
however the circuit is unable to reflect any wave form..
no signal have been receive at the receiver end..

what might be the problem? is there any simplified version??

i had upload the board print screen
i had added 74LS14 ic in both board, but both can't work..

Your schematic has only five connectors and three capacitors.
It does not have a receiver circuit, does not have a 74LS14 IC and does not have a power supply.

Your receiver does not have a part number.
Your power supply does not have a voltage.
Your 74LS14 does not have any Schmitt-trigger inverters.

Is the output of the 74LS14 always high or always low?
