LED blinks irregularly. And since i don't have access to an oscilloscope,which i do regret awfully, i haven't run a test on the oscilloscope. Also,i am not using the watchdog reset timer. Voltage levels are also pretty much stable. One more thing,i have connected the the output of the comparator directly to the interrupt pin,without using any pull-ups. Does that affect in any way the working of the interrupt? |

| then try 'selective grounding' | 01/01/70 00:00 | |
| This might be the reason | 01/01/70 00:00 | |
