Well I have finally received the time delay modules. Unfortunately they are a time delay off not a time delay on as I had hoped. Once I changed the solder blobs to the configuration in the diagram you found for the LED wiring it worked. When powered up the LEDs lit for 10 seconds and turned off. Changed the dip switch setting for 20 seconds and that worked. So it would appear that I will need to add the transistor and resistor to invert the output.
The diagram looks like you are showing a 1K ohm resistor and a 2N3904 transistor. The resistor is hooked to the base and - to the collector. The emitter goes to the LEDs. Do I have that right? It has been awhile since I worked with transistors so this is my best guess.
The diagram you provided was based on 5vdc for the circuit. I bought both 5 and 12 v LEDs to play with. Would the resistor and transistor work for both voltages?
Looks like I’m getting closer but no cigar yet.
