About this document
ADC Voltage Measurement in Light Conditions by usamadar707 is a document available to read on EtoBox.
The document describes an experiment measuring light and dark conditions using an Arduino. Figures 1 and 2 show serial monitor readings of 15 for dark and 300 for light conditions. The code measures analogue voltage which is related to the ADC reading by a formula dividing the system voltage by the ADC resolution. For a dark reading of 15, the analogue voltage is calculated as 0.073V, and for a light reading of 300 the voltage is 1.46V.
