am a sanguino/avr newbie
im trying to use the Analog Pins for interfacing LM35 temperature sensor
the pins give random values for whatever Analog input
i uploaded the AnalogInSerial example for this purpose
the connections where same like the one instructed in arduino AnalogRead reference page
can anyone help me out?
I've been looking over the datasheet on this, but haven't found a definite answer to your question. I suggest looking at this thread as it may provide some useful information for you: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1224321879
thanks flyboy..for ur response..
i have gone through that thread...it speaks about minus temperatures ...
might be useful if i solve the following issue
my problem is like the ADC in the sanguino board which even with a potentiometer shows random values
How do you have your potentiometer connected? You should have one end tied to ground, the other to +5V and the wiper should be tied to your analog input. Let's start there and work from that. I think once you have some confidence that you're reading what you expect to read, then you can move on to the sensor.
kishore, were you able to get your test up and running? Did you find the problem? Hope it is working now.
