Hi guys, I have a signal that I want to input into a digital input, basically it is just a square wave about 0 to 0.5v, so I think I need to boost it up to around 0-5v so that I get reliable readings by the picaxe of high/low states, I have some 2n3904 transistors here and a 600 odd assorted values resistor pack, so I'm hoping that I can use these to increase the signal so picaxe will see the signal properly.
Does anyone have a schematic for a simple circuit to do this using the parts I have on hand? I have looked around to try to find something suitable but it is a bit hard to know the exact terms to use.
Thanks.
