I'm a complete novice to most things computer/arduino related, but I think I've exhausted the resources I can find at the moment. I was hooking up a TMP36 to my Arduino Mega 2560 as outlined here
for the first time and not getting any data. Moments prior, I'd hooked up up to a TSL235R (which worked without a hitch). As I was poking around my wires to see if something wasn't plugged in, I noticed that oh-so-distinctive burning electronics smell. As I was unplugging everything, my finger brushed the TMP36, which was hot enough to leave a small blister.
The TMP36 heats up if you connect it backwards
, but I triple-checked that I had the pins as per the Ladyada link above. I figured it was just a defective part, so I tried to go back to the TSL235R, and....timeout error. Can't load any code at all. I poked around online and found out a loopback test as per this page
and nothing echoed back at all.
I've found lots of instructions for how to do a loopback test, but I'm at sea as for how to interpret it. What's my next step? And can the arduino be salvaged?
Also--I may have had the dreaded triple exclamation mark in there somewhere, but I deleted the file and can't go back and check now.
