Hi all,
I'm new to arduino trying to work my way through a handful of examples. I'm currently working through a basic temperature reading example: http://oomlout.com/a/products/ardx/circ-10
For some odd reason, I keep getting consistent readings of -50.00. Any thoughts? I'd really appreciate any help you can provide!
Please post YOUR code as there might be some diff..
Looking at the examplecode and reasoning backwards temperature == 0 (-0.5 *100 == -50)
float temperature = getVoltage(temperaturePin);
temperature = (temperature – .5) * 100;
That implies that the analog read allways read 0 so it is connected to ground so
Try the code without a sensor (that should make the analor line float and give different reading.
