Hello, good morning.
Currently i'm having one problem with my Arduino, related to the voltage regulator.
When I plug my arduino directly to the USB, my Voltage Regulator gets really hot and after few seconds all the led lights lose bright and I lose USB connectivity to the arduino.
What is strange is that there are 3 different situations:
1 - When I plug just the arduino in the USB cable = VR really HOT
2 - When I first plug external power supply AND THEN plug USB cable JUST in the Arduino = VR ok, not getting hot.
3 - In situation #2, when I do it WITH the Ethernet Shield, it starts getting hot.
Do you have any knowledge to share about this?
