Gravity 2-Channel 15Bit 0-10V ADC Module

1. Example Code for Arduino-Read Data Using I2C

This project demonstrates how to read the voltage value of channel 1 from the Gravity: 0-10V 15-bit High Precision Dual Channel ADC Module using I2C communication with an Arduino UNO controller. Users will learn how to wire the module via I2C, install the required library, and use sample code to obtain voltage data.

2. Example Code for Arduino-Read Data Using UART

This project demonstrates how to read the voltage value of channel 1 from the Gravity: 0-10V 15-bit High Precision Dual Channel ADC Module using UART communication with an Arduino UNO controller. Users will learn how to wire the module via UART, install the required library, and use sample code to obtain voltage data.
