      I think you connected the IR sensor incorrectly. I have done IR experiments several times, but I have never faced such problems. Please check your connections.

    Hi sir, thank you for the nice tutorial! I just want to get clear, what does C1 and C2 mean? does it mean, capacitor? and what does U1 and U2 mean?

    also, can i use this kind of circuits in a white breadboard? and in your black breadboard, where is the positive and negative in there? could you please post a tutorial of this using a white breadboard? if possible.Thanks man.

    Should the emitter of the BC557 be going to the +5V instead of the IR receiver output in the schematic above? Seems that way in the breadboard component layout and on my own test here it works that way.
