I made a simple project with an Ardweeny and 4 shift registers to drive a total of 32 LEDs.
I can download the program and run it for days either powered by the USB cable or from a wall transformer supplying a 5 volt regulator WITH the FTDI installed.
If I remove the FTDI it will only run about 30 seconds on the wall transformer and then lock up. ???
I ordered two more Ardweenies and they each act the same.
I am totally new (but very impressed) with Arduino and the Ardweeny.
I am assuming it should run without the FTDI. Has anybody else had similar issues?
