How to read voltages with analogRead(): Arduino Course for Absolute Beginners
By Robolab Technologies In Arduino, Atal Tinkering Labs ATL, More InfoIn the last lesson you learned about using the analogRead() function to collect data from a sensor connected to one of the Arduino’ analog pins. The range of data we received from the analogRead() function, was mapped from 0 to 1023. What if we wanted to know the actual voltage being applied at the pin?
