    as i hav to do sensor in my project so if anyone can tell me the right way to make a beacon sensor althogh i hav started it but its confusing i split the circuit in 3 parts in 1st i made the circuit of an led and phototransister from which i got a perfect square wave when attached to the oscilloscope then i added a voltage comparator into my circuit in order to amplify my signal and after that I'll put filter to get rid of the noise and other unnecessary signals
    Can anybody help me out of this my voltage comparator design is not working!
