    I found this in my lair... I mean studio. I think bernard wrote it out for me. Can someone help me figure out the parts I need? I don't understand the parts that go inline. I have the light, board, and batterys and understand anode and Cathode but not sure what the other parts are. I require someone with the patience of a teacher or saint on this one. Thanks in advance.
    Dashed box on right is the motion kit I purchased.

    What is the purpose of the components in the box on the right?

    That is the ir sensor I purchased for parts or to use straight up. It was a good buy on goldmine.

    The components are simple:

    The zig zag symbols are resistors

    D1 is a diode

    C1 is a capacitor

    2N6427 is a transistor

    Do they have any certain type or size? can I order all this anywhere?

    For the transistor and the diode use one of the part numbers below or above them.

    For the resistors use the value noted and order them to be 1/4 W.

    For the capacitor buy the value noted and take one with a voltage rating of 25V.

    I'll be ordering some tomorrow. Anyone know what D2 and D3 are?

    D2 & D3 are used to drop the 12V supply to 10.6V to match the 9V supply of the PCB assembly. I think any diode with current rating 1 amp will do the job well (1N4001/ 1N4002/.../1N4007) If you think 10.6V is too high for the circuit, you may add one more diode(totally 3) to get the supply voltage down to 9.9V.

    So D1, D2, and D3 can all be IN4002's? Parts ordered, will update. Thanks

    How did I miss this thread?? As described, D2 is a white LED, Vf 3.4V. Transistor D1326, you have it. With postage RS is cheap.

    Might review, "Need to use IR sensor with artwork" ,page 4 for pin id on D1326.

    One more thought: With your present PIR ,can use 6V or 12V, output " active high" so might try a bright white LED.
