Just think of voltages as digital signals of value 1 = +voltage and 0 = 0voltage.. THe +voltage depends on the device. I am not sure about the Pi but safe to think of half way. So at least +1.8v will give you good logic. It does not need to be shorted and better if it is after resistor to protect battery and other stuff. | |

Sep 10, 2013 at 17:41 | comment | added | BAReese | Some clarity... by safe, I mean if pin 7 was configured as input and was shorted to pin 9 with a screw driver, would it cause any damage. As for the optical transistor - I wasn't very clear. I'm thinking of an IR receiver like what is found in a TV/VCR/DVD player. I would like to be able to record the code output by the TV remote and store that for playback (though an LED). Is that even possible? | |
