rshomberg 6:8cfa0216554f 5 Purpose: Read signal from TMP36 connected to pin20
rshomberg 18:699b41309be7 6 Toggle switch connected to pin07 activates SD logging
rshomberg 18:699b41309be7 7 Log: Time Elasped, Current Voltage, Current Temp, Delta Temp
rshomberg 18:699b41309be7 8 Finish log -> save file and send to USB serial port
