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? TNX
