I downloaded the circuit without transformer of five volt but it did not work. When I give supply from usb port of CPU it worked very well. Can you please let me know how to make 5VDC power supply without transformer. Please help in this regard, if possible. Any reply shall be highly appreciated. Thanks in advance!

You must triple check all your connections and make sure you have all ICs and Photo devices around the right way. As a tip I would mount the ICs in IC Sockets, this allows you to check voltages and polarity before you insert the ICs. While building this I actually damaged IC2 twice and had to replace them ! I will send you my document on how the circuit works. Virender,

Either that or the data sheet for the photo transistor was wrong and I have the emitter and collector backwards. Anyway it worked OK when I re-did the connections (again)and swapped Pins 5 & 6 on IC2b.
