Making a light sensor with a photoresistor. Possible?
July 20, 2008
Hi guys, i've just read this article from SoR http://www.societyofrobots.com/schematics_photoresistor.shtml
i was wondering if this could also be done with a picaxe. the article talks about measuring "the voltage drop across the resistor with the analog port of your microcontroller". Do you know if/how i can do that? And also, can i really make it a sensor? (attach it to an input port and receive values from it).
Because if i can do this, i'll rather not buy this one http://letsmakerobots.com/node/871 which i guess is more expensive and less DIY (if you have seen my robot you probably now i like extreme-DIY stuff :) )
