The design brief is :motion sensor sensor lights a bulb when it detects someone passing through.I will appreciate if anyone can suggest a simple circuit using just these:bulb,ID diode and photodiode
Please show us your best attempt and we can go for it.
Ty Mr Eric for aiding me.Can you recommend me a good and model number of transistor pls ?I have a voltmeterhi b,
This is a marked up version of your Bread Board layout.

Update:
You need a transistor to amplify the change in output of the Detector in order to drive the LED.
What transistor do you have on the bench.?
Do you have a volt meter.?

I have seen the voltage by checking the testpoints it is 4.5 voltage + and -
