Wawa:
A scope looks at voltage, not at ratio.
A smoother scope voltage is therefore useless.Better to take a bunch of readings for averaging.
unsigned int total = 0; // reset
for (int x = 0; x < 64; x++) total += analogRead(A0);
Leo..
I thought the pressure sensor has a analog voltage output based on pressure input. So the nano reads the analog signal from the pressor sensor as a voltage. So intern a wavering voltage equals a wavering reading. Am I wrong to think of it that way?
