Hi I have Arduino Uno , today I tried to measure the voltage of pin 3.3 I bought digital multimeter and the result was 0.49 - 0.5 is this possible?? or am I doing something wrong? I tried the 5v pin and the result is correct about 4.96V what might cause that? regards

My arduino Uno is not producing 3.3 voltage
