June 11, 2012 by JTOME	Anybody know the specs for the capacitor connected to pins 22 and 23 of the MCU in the digital weight scale project tutorial?
June 11, 2012 by missle3944	JTOME, I'm not sure what the value is but my guess is that its there just to smooth out some voltage spikes or make it easier for the ADC pin to read the ad620. Try it with out the cap and see if it does anything. -Dan
