Its an Arduino UNO R1, and I'am using this multimeter: http://www.petervis.com/meters/Excel_DT9205A/Excel_DT9205A.html
I know thats impossible but is what I'am getting from the multimeter.
I connect the pins to an breadboard and I measure the Vin and 5V and 3.3V connected to the ground pin next to it on arduino.
I need to solve this to know the exact voltage to use the TMP36 to measure the temperature.
I also read the voltages directly from the voltage regulator and I'am getting the same thing!
Can this happen because I'am feeding only 5v? In arduino page says minimum 7v.
