this the circuit i built (transmitter and receiver)for my project,As you can see i kept 1 white LED.Instead of the voltage at R1,i kept frequency generator to give square wave.
**broken link removed**
the above picture is the waveform from the lm339 comparator when i used only 1 LED with the single transistor.
**broken link removed**
this is the waveform i got from using 1 LED,the signal is not proper.y is it so ? am i missing something ?

any suggestions would help.thanks
