    Sarcasm? ;) Let's try to use it as good as we can. Keep pointing new users to the tool. Who dares to explain the usage - feel free to do so.

    Heheh, no- not sarcasm. You wont believe how many times I wanted to answer with a schematic and decided not, because all the online tools are are a mission. I enjoy this implementation as used on Electronics Exchange. Albeit, a bit late, but better late than never :)

  • It would be nice to have something similar for flow charts too.. not sure if there is SE implementation of it though.

  • make that a feature request if you like (but don't get greedy). You may also rework all your previous answers :)

    Are you sure the LED won't damage? LEDs typically operate at 10 mA, don't they? This one is simulated at 30 mA. Jan 24, 2016 at 22:52
  • @ThomasWeller Did I mention I was a n00b? Jan 24, 2016 at 22:59

    It's all good. Continuous 30mA, peak 120mA according to the datasheet.
