I'm new to arduino and working through the 15 projects in the starter kit.
Project three uses the TMP36 sensor.
It works fine (reads 15C) until I put my fingers on the sensor to increase the temperature reading.
Then it jumps up to temperatures in the 40 - 50C range and stays there for a considerable amount of time after I remove my fingers.
I modified the program to take 20 sample readings and then to use the mean of the 20 to give a reading. It didn't help.
Anyone had this experience and can explain why it happens?
