Noise on Voltage/Current analog read


Hello Howard, im getting very different values for voltage and current reading, im using 2k2 and 220 Ohm for voltage and ACS712 20A (0,1V/A), some instant measurements differs in about 1V/1A from others. Tried to install 1uF electrolitic or 0,1uF ceramic capacitors but didnt get any sustancial change, there are a lot of example codes for average analog read but dont know how to implement them in your OCS.
Could you give some code for average?
