 To the best engineers, scientists, and thinkers, something that is "hard" isn't something to avoid; it is something that begs for us to prove that we can do it. STEM is built on the very idea of trying something, failing, and trying something different. - Bryan Herbst [more] |

Analog in on OI: Heads Up!
 Heads up: The OI will output 127 for what it perseves as infinate resistance. I'm not sure of the exact threshold, but my theory is that when volts <= 0.1, it outputs 127. But noise (flickers between 0 and 127) goes until about 0.110 or 0.115. So if, as an example, you wire a potentiometer to p4_aux, when the pot. is all the way down, p4_aux=127. when it's a little higher, p4_aux=0. also, 127 appears in it's "normal" position (midway 'round). So you can't just put in an if statement. I hear this is by design. So watch out! |
