same I2C addresses devices are used; So we write the SoftwareI2C library to use digit port and analog port to enable multiple same I2C addresses devices work on Arduino. I2C Scanner for Arduino¶ I2C Scanner is a simple sketch that scans the I2C-Bus for devices. You can upload the code to your Arduino to find out the I2C address of the modules I2C sensor modules usually add another 10k each, so our 'net pullup resistance' on the I2C bus wires is usually: 50k // 4k7 // 10k = ~3k. With a 3.3v rail that means the devices draw 3.3v / 3k = 1 mA during communication which is fairly normal ( 3mA is max current allowed by the spec) for total wire lengths below 1m How the code works. After including the library, the next step is to create a new instance of the LiquidCrystal class.
