Using I2C: True digital to analog conversion on the Arduino Uno ​The Arduino Uno, with its Atmega328P MCU, does not have true digital to analog conversion capability. For this, we turn to an external device, the PCF8591.

The PCF8591 is a I2C module that brings analog-to-digital and digital-to-analog conversion to your Arduino projects.

Learn how to use this I2C-based module in your next project.
