Circuit Diagram
The MCP4725 DAC is connected to the Arduino via the I2C interface, where digital values are sent from the Arduino to control the DAC output.
Steps for the Experiment
- Connect the MCP4725 DAC module to the Arduino via I2C (SCL, SDA, VCC, and GND).
- Upload a program to the Arduino to send digital values to the MCP4725 DAC.
- Observe the DAC's output, which will generate a corresponding analog voltage based on the input values.
Explanation
The MCP4725 DAC converts digital values sent by the Arduino into analog voltages, allowing precise control of voltage outputs for various applications.
Results and Observations
- The analog output voltage of the MCP4725 should vary based on the digital values sent by the Arduino.
