I was teaching a class yesterday and I had 6 students building Circuit #7 using the tmp36. None of them could get correct voltage readings from the sensor. We tried wiring power and ground directly to the red board and also doing the wiring exactly as it shows in the book. I also tried plugging the board into an external power source. Nothing worked.
Does anybody have any idea why this does not work? Could all the tmp36 sensors be from a bad batch?
Thanks
