AVR Power Supply Noise

2006-07-10 by behrooz_hariri

I connected a car battery (12v) to LM7805 to fully minimize power
supply noise. But still get errors in executing codes.
I read a film capacitor 0.1uF is necessary after regulator. I used
electrolyte one 0.15uF.  Does it make difference? 

I use a breadboard with some wire rather twisted and 10cm long. Is
this a reason for MCU malfunction?
