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.

What is the significance of the number of bits in an ADC?

How do you convert the output of an ADC to meaningful sensor values?

How does a potentiometer function as a sensor in a circuit?

What are the voltage limits for an ADC, and why is this important?
