Hi, I am using the example code below. I appear to be limited to an array size of 32. Any thing above this results in negative readings. I would like to average at least 100 readings. Is this possible? Thanks /* Smoothing Reads repeatedly from an analog input, calculating a running average an…

The variable "total" is of type "int" which will roll over and become negative at 32k and since an analog-read yields numbers up to 1023, having 32 readings may cause a rollover. Change the data type from "int" to "uint32_t" (which equals an "unsigned long") and see what happens. All your "int" data…
