Hi SirHobbes,

Have you tried flashing a different program to your chip? Is it just the ledarray code that does this?

Some pictures of your setup might also help us spot the issue, and ass Rick said above, this problem most likely related a battery or power issue.

The program is not the problem is the others do it as well, so it is a wiring problem...

The issue is a power issue, i ran just the mcu with a battery and the code went to the mcu fine,but the power adapter does not work. i do not know because the voltage coming from it is more than the battery at 8.90 volts. this is a very odd probelm....

Hi SirHobbes3,

Perhaps you are wiring up your power adapter incorrectly. Double check the output leads have the voltage you expect, and make sure you are hooking it up to the 7805 correctly.

Problem solved!!

We went and bought a 9v power supply at radioshack, it fitted right and all, but it only porduced 300milliamps, the original produced 700. So we ordered another from AllElectronics and it should work, it's same as the original.

Thanks for all ur help, and we found the problem!
