analogRead in Ardiuno: Arduino Course 4.11

This lesson covers the differences between analog and digital signals, focusing on how analog signals can be converted into digital values using an Analog to Digital Converter (ADC). The instructor uses real-world examples and a game show analogy to explain the concept of ADCs. The lesson also includes a practical demonstration of setting up a circuit with a potentiometer to simulate a sensor and read values using an Arduino.
