In Arduino Uno the i2c bus is available on pins A4 and A5. Using I2C communication bus we can connect many devices at the same time using only two wires as each device has its own unique address. This way we can connect so many devices with for example Arduino using only two wires. By the easy implementation I mean that such devices need only 2 wires. I2C communication Bus has become very popular and now commonly used by thousands of electronics devices because of its easy implementation. I will write programs for the BMP180 and HMC588L Sensors once I explain the basics then I will write a combined program. I would appreciate your support in this way!īefore I am going to explain the multiple Sensors interfacing, I would like to explain some basics. I may make a commission if you buy the components through these links. Without any further delay let’s get started!!! Amazon Links: Combining both the Sensors and access the data of each sensor separately.HMC5883l Sensor Introduction, Pinout, interfacing, programming and testing.BMP180 Sensor Introduction, its Pinout, interfacing programming and testing.So today you will learn how to use i2c supported sensors without using the addresses. Almost all the i2c supported sensors have libraries and programmers has made it very simple for us, we only read the values by calling certain built-in functions. I searched Google and YouTube, I found so many tutorials but they were talking about the sensors addresses and they were rewriting the entire code, reading and writing the hex codes, performing all calculations and so on. In this tutorial, I will practically demonstrate how to use the BPM180 and HMC588L with the Arduino. There are situations when we need to use multiple sensors with the Arduino Uno, but due to the limited number of the I/O pins we are not able to connect many sensors, but thanks to the i2c supported Sensors, now we can connect multiple i2c sensors using only two wires. Watch Video for the Practical Demonstration:Īrduino i2c Scanner and Multiple i2c Sensors Interfacing & Programming– in this tutorial, I will teach you the simplest method on how to scan the address of an i2c supported Sensor and how to connect multiple i2c supported sensors with Arduino without using the Sensors addresses.About the HMC5883L i2c supported Sensor:.
