hi guys im facing some sort of trouble with my arduino and eth. shield.. i just powered it up using a 12v 2amps adapter to troubleshoot my relay work though the relay works but the shield suddenly goes blinking the LED indicator of COLL and PWR is just blinking and i also tried to power it up using a usb-serial cable but it cant.. btw the arduino was not damage, does powering it up to 12v 2amps cause the problem with the shield?..
ps. i do have a 9v 1amps adapter for arduino.. i just tested it with the 12v to know if the relay will work the on off sequence even thou it has its own 12v adapter..
pps. my relay is a D I Y i just removed the 5V+ connection of the board to the MCU at it works the on off sequence and shit happens the eth shield goes blinking..
