I don't see how the opto can ever be turned on? Its cathode is always at highest potential in the left half circuit.

- aceperry 12y agoYeah, the LED in the opto isn't even connected correctly. I doubt it would ever light up. I left a post on the website explaining how it should have been setup.
- kwantam 12y agoAh, I see the confusion. The power supply should be connected such that the positive terminal is on the left. If you look at the breadboard, you can see that this is, in fact, what's built. My description of the circuit's operation above is accurate when the power supply is properly connected.
