I am very new in electronics so I am asking to help me with this. Sorry for my poor English
I attached my solar panel multimeter scheme. I need that arduino reads Voltage and Current at the same time. I have read a lot of posts in this forum, but apparently I am too stupid to do it by myself. My arduino reads voltage correctly, but I don’t know how to measure the Current.
I made something like this: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1205745528/0
and blew up some LED’s. So I need something else. Can someone please correct my scheme so that Arduino Analog Input 1 reads Current correctly? Can I use something else instead of LED? I just don’t want to blow up my Arduino Duemilanove.
P.S. 1omhs resistor is 5cm copper wire.
