Arduino multiple i2c sensors Connect the SDA pins of both the sensors with the A4 of the Arduino Uno and also connect the SCL pins of both the Sensors with the A5 pin of the Arduino Uno. Arduino’s I 2 C communication library is called the Wire library. . Note: 4 OLED Displays… Aug 31, 2022 · Yes, I2C is a bus designed for connecting multiple i2c devices via the same bus as long as the i2c devices have different i2c address. Both SCLK pins of the 2 sensors connect to pin 4 on the arduino. In the case of the addresses are duplicate, you need to change I2C address of the sensor/device to make it unique. And these complete the hardware connections from the arduino microcontroller to the I 2 C sensors. Code. Watch the Video! In our case we will use 4 OLED Displays as an example, but you can use any other I2C modules/sensors if you wish. To change I2C address of a sensor/device, you need to read its datasheet or manual. Multiple i2c devices Arduino code: Jun 19, 2018 · And these complete the hardware connections from the arduino microcontroller to the I 2 C sensors. The code so that we can connect the I 2 C TC74 sensors to an arduino microcontroller is shown below. If you can read the temperature sensor, but not the IMU, run the i2c scanner to see if you can detect it first. These are tied together from both sensors and connect to the +5V pin of the arduino. Pin 5 is the VDD pin, which is the positive voltage power source for the sensor. Arduino Connect Multiple I2C Devices: In this tutorial we will learn how to connect several modules with an I2C connection to arduino. Make sure that each sensor/device should have a unique I2C address to these sensors/devices. So, both the sensors can be connected with Arduino’s pins A4 and A5. Apr 19, 2025 · As both the Sensors HMC5883L and BMP180 supports the i2c communication. bmwhxrn fwp gkaj ptne eanwl gyq ynepa qwnsi lhyxz tsgfj
