I have an Arduino setup from which I can control my RGB LED strip from my computer using LAN.
It worked like a charm in the start, but after two days, my Ethernet Shield W5100 for Arduino Uno stopped working, and I can't figure out why.
When I connect the Ethernet Shield, the red LED "pwr" is solid red and the "FULLD" flashes orange every second.
I have followed an Adafruit guide, connecting the Arduino as such:
On top of the Arduino, I have the Ethernet Shield. All this is powered by an 12V/4A power supply connected to the Arduinos 2.1mm jack.
As I said, this setup worked fine for a few days. While it was on, I noticed the Arduino getting somewhat hot, but some google searches assured me that Arduino Uno can handle high temperatures, so I did not pay any attention to it.
The LED strip is not too long - about 2 meters with about 150 LEDs.
What I have tried:
- When I detach the Arduino from my breadboard, the Ethernet Shield will still not connect
- I have tried connecting the Shield to another Power Supply (Computer USB) using another Arduino, but the Shield would still not connect.
- I have added a debugging Serial.print message in the Arduino loop function. When using serial monitor, this message is printed over and over again (as if it is stuck in a reset loop)
- I have verified for MAC address collisions, even changed the MAC address of the Shield multiple times.
Have I somehow burned the Ethernet Shield? Why won't it work anymore?
