So I i am a bit confused, I have been messing around with electronics for many years but I haven’t done much in this depth yet. I was wondering, if I have a photoresitor or thermoresitor, just the raw component and I want the botboard to read these values how would I go about it? I guess you can connect them directly to the input pins and read the analog value? Is there a tutorial or something I could read about this, or could someone show me a diagram and sample code? Thank you for all the help you guys have been giving me!
You can’t just connect a photocell or thermistor to an analog input. The analog input is designed to read a voltage. In order to convert this variable resistance to a voltage you make a voltage divider from a fixed resistor and the variable one. For example look at these.
WOW! That was really easy… thank you, I don’t know why I didn’t see those, I really did look for some diagrams :mrgreen:
I can’t believe it worked on the first try and it only took this amount of code…
[code]
light_int var word
main
adin P16,light_int
serout s_out,I9600,[REAL light_int, 13]
goto main[/code]
Thank you again!
Win!!! You’re welcome. 8)
