Introduction
This experiment demonstrates how to acquire analog signals using the ADC (Analog to Digital Converter) on the ESP32. The ADC can convert real-world analog signals into digital values for further processing.
Materials Required
- ESP32 Development Board
- Analog Signal Source (e.g., potentiometer or sensor)
- Breadboard and jumper wires
- Arduino IDE
No Ads Available.
Circuit Diagram
Connect an analog signal source (e.g., potentiometer) to one of the ADC pins of the ESP32.
Steps for the Experiment
- Connect the analog signal source to the ADC pin of the ESP32.
- Write a program to read the analog signal from the ADC pin.
- Upload the program and monitor the digital readings of the ADC in the Serial Monitor.
Explanation
The ESP32 has a built-in ADC that can read voltage levels from analog sources. This is useful for sensor interfaces where the output is analog and needs to be processed digitally.
Results and Observations
- The Serial Monitor should display the digital values corresponding to the analog signal input.
