  1. think I get what you mean visually in my head "across" but I'm not sure if is parallel or in series. I'm guessing in series... jesus this is sad but when I recently did a PWM GPIO audio output "mod" thing (pretty much followed Adafruit's tutorial word for word" I didn't get how the low pass filter I guess they weren't ordered eg. flew from one side to another regarding the combination of the resistor(s)/capacitor/film capacitor.
  2.  
  3. I have a 50K Potentiometer (big one) will try that, this is really cool seeing the data be updated
  4.  
  5. The one I've got looks just like this, my little "Arduino intro kit" has it but doesn't say wattage rating.
  6.  
  7. Oh but the specs say 0.2W... hmm this does say 20kOhms probably wrong one.
  8.  
  9. Another one that is 50kOhms is 0.2W power rating...
  10.  
  11. Yeah I guess I'm not getting the 1W part in your... oh wow 50 ohms not 50 k ohms hmm
  12.  
  13. Lowest I have is 220 ohm... guess I could try some leds, nope
  14.  
  15. Lowest resistor I have is 0.330 ohm on 2K DMM setting... from the parts list lloks like it's one of the 220ohm resistors. 330 ohms then I think.
  16.  
  17. Try that in series would use the V = IR in this case to note drop in voltage? Would it be more stable with something to "fight against"?
  18.  
  19. I heard something about solar panels needing a constant draw "they could break if exposed to the sun and power produced not being used" I don't know... really ignorant haha.
  20.  
  21. Oh wait maybe I could just start cutting low gauge wire... nope low resistance in the single digits... hmm
  22.  
  23. Well will plug the 330 ohm resistor in series I'm assuming in the order of Solar Cell V+ -> resistor -> ADC
  24.  
  25. Sorry rambling worked an entire day sucked very tired
  26.  
  27. Just a quick sample test with same yellow ambient light, in the low 300's high 200's (with 330Ohm resistor), hmm, not much of a change...hmm using a 10K one, I am seeing more double numbers in the real time half second sample
