delay(1000); } In this example, we're using the Wire library to communicate with an I2C device with address 0x12 . We're writing data to the device, then reading data back from the device and printing it to the serial console.
Here's an example code snippet that demonstrates how to use the Wire library to communicate with an I2C device:
#include <Wire.h>
The Wire library is a built-in Arduino library that allows for communication between devices using the I2C (Inter-Integrated Circuit) protocol. In this post, we'll take a closer look at the Wire library, its functions, and how to download and install it for use with your Arduino projects.
const int deviceAddress = 0x12; // I2C device address download wire.h library for arduino
void setup() { Wire.begin(); // Initialize the I2C bus }
The Wire library is a part of the Arduino core libraries and provides an easy-to-use interface for I2C communication. I2C is a serial communication protocol that allows multiple devices to communicate with each other using a single, shared bus. The Wire library simplifies the process of sending and receiving data over I2C, making it a popular choice for Arduino projects that require communication with I2C devices. delay(1000); } In this example, we're using the
Wire.requestFrom(deviceAddress, 1); // Request data from device while (Wire.available()) { char c = Wire.read(); Serial.print(c); } Serial.println();
