Hey guys- I have a bunch of sweet (hermetically sealed) high quality 1 Meg pots that were given to me. I know you are supposed to use 10k pots on ADC inputs....but the 1M pots seem to do fine in my test circuit. I understand that the current available thru the 1M's for the ADC reading (charge...

Hi All- How do you get the program and Variable windows up on screen while animating the circuit? I need to be able to check ADC outputs. Also can you think of any reason why I HAVE to insert a 30 ohm resistor between the GND side of my ADC potentiometer and GND for the circuit to work properly?

Hey Guys! Hippy & technical saved my butt a couple years back with an 18x project and I'm still so grateful! Anyways- couldya help a newb with another basic programming problem? The project requires lighting an LED for one timing cycle upon a SWITCH ON condition, and lighting the LED for a...

I'm ONE shy of inputs on my 18x. But I've found that if I switch 5v into one of my used ADC inputs I can force the result I need. (IF ADC > 250 THEN dosomething) My only concern is damaging the op-amp that normally feeds the ADC input with a 0-4.9v signal. The trick only works with a straight...

After all the help I've gotten on the board, I thought this might help someone...... After chasing RANDOM glitches with a pressure sensor input to an op-amp to the Picaxe for months.....It came to me in my sleep that the flux left on the board might be conductive enough to cause the...

Hippy or Technical: In the following program I need to use a 2 position DIP switch to allow 4 different settings for the PWMMAX parameter. I have 2 unused inputs on the 18X. (6&7) This will be a user adjustable setting to allow for different max motor speeds. You guys have helped me SO MUCH...
