oh yeah me too right there. I've collected every common resistor from 47ohms to 3M ohms, many different capacitors, and op-amps from the synthesizer I'm building. It's better than the radioshack parts cabinet.I have a ton of npn transistors so they come to mind occasionally, I got them for a LED project I never finished ,-,
I promise the 100k is there. It's underneath the 10k, nothing is shorting either. According to the radioshack baggie I have it wired in the correct direction, but I guess I could try swapping it either way and see what happens.First of all you swapped the collector and the emitter. Also I don't see the 100k resistor
From left to right in the diagram. Collector, Base, Emitter. According to radioshack.Mmm can you draw a schematic using directly a drawing of the transistor? Maybe I misunderstood your connections from the picture.
Ahh I see now. The radioshack diagram says "Pin diagram viewed from bottom" damn you radioshack!!According to this datasheet the order is EBC from left to right (according to your drawing point of view)
I know how you feel Let me know if it worksAhh I see now. The radioshack diagram says "Pin diagram viewed from bottom" damn you radioshack!!
You don't even realize how many times that's gotten me so pissed at something that should've worked but didn't."Pin diagram viewed from bottom" damn you radioshack!!
That's odd. Can you measure the base voltage both with the button pushed or not?Swapped the transistor and now the test spot just stays at 3.3v whether the button is pressed or not.
.25V? It also looks like that pull-up resistor (the 100k one) is not connected to 3.3v...Interesting, from the tact switch, unpressed is .25v and pressed is 1.7v. Apparently it isnt ground! It's a black wire but its carrying voltage. Also the wire labeled Key on the screen is actually ground. I shouldve tested that before but I just assumed.
So across the resistor there is like ~3V?Yes, .25v. It is connected to 3.3v, the wire just leads out of the picture to the controller board power.
