See the image below to understand how to locate the correct pins on your board. Just run this example and get its addresses. That can be useful if you donвЂ™t know the address of any I2C device or just not sure about it. Next we send one bit 0 that indicates we want to read the value from the register 0. Inside the function we start the transmission by using function beginTransmission () from the Wire object which needs the address of our sensor.

For example, the pins used for MKR WiFi 1010 are D11, D12, while the pins for UNO are D18, D19. OLED I2C Display Arduino/NodeMCU Tutorial: The very first program you write when you start learning anew programming language is: 'Hello World'.The program itself does nothing more than printing a. ESP32 I2C Scanner (Arduino) LAB The I2C Scanner example is a very common Arduino sketch example to scan the I2C bus for available devices and get their addresses (if found). In the code we use function readtemp () that returns an integer, in our case the temperature.
