Photo switch / transistor - any suggestions?

ACK - I just noticed something wrong, the 10k resistor I used to quickly discharge the cap, but...

  1. Ground is not connected, does not matter what value that resistor is LOL - it's going glow just as bright no matter what you use, after hooking up ground, 10k bled the cap dry, if you're going to use it to discharge the cap, a lot higher value, try around 100k, it works for me...

Video uploading.

To make it work, connect ground, then place a 100k (or whatever suits you) between gnd and + on the cap, as the Light goes off, the voltage drops, the cap will drain via ground .

P.S how do you embed a video via this forum ? or is it disabled here..

Gotcha. Thanks again - really appreciate you taking the time to figure this out. :slight_smile:

And, no idea how to embed a video here - the link worked fine though - very helpful. :smiley:
