Hi, I'm pretty new in electronics (decades of experience in computing, but close to 0 in electronics, this has to change!).
I read this page which does not say much: http://www.libelium.com/squidbee/index.php?title=Adding_a_light_sensor
Why is there a 1K resistor in it?
Why is it a 1K resistor and not a different one?
Why is the resistor at the top and the sensor at the bottom and not the other way around?
I must be missing some basic knowledge, please help me.
I hope I can help others when I get better. For now I'll browse this forum for computing questions I can answer
