Tutorial 09: How to read voltages with analogRead(): Arduino Course for Absolute Beginners (ReM)

This tutorial covers using the analog read function on an Arduino to convert raw data into voltage values. It explains the necessary materials, circuit setup, and code implementation, including variable initialization and conversion using a float data type. The tutorial also discusses the float data type's characteristics and limitations. Finally, it demonstrates how to verify and upload the sketch, using the serial monitor to observe voltage changes.

Summarize the steps involved in setting up the circuit for reading analog voltage.
