Sometimes we need extra precision on our projects, here we need to understand the resolution of an adcThe regular arduino have 10 Bit resolution, if most sensors are 0 to 5 Vdc and the biggest number we can take is 0 to 1023 that means that we have 4m Volts/bitBut using the arduino i2c port we can u…By: jmorles // Read more: original article.
