The Arduino Uno R4 WIFI provides one I2C bus on the pin header, which has no pull-ups on the board. Thus, we need to connect a pull up resistor between SDA and VDD and SCL and VDD. In the example two ...

Next steps shows how the master (Arduino) reads from the slave I2C device. Wire.requestFrom(address, 1) command expects to receive 1 byte of data from the TC74 sensor. Wire.available() waits for data ...

This works because many devices can safely ignore pin-swapped i2c traffic on their input. I’ve tried this successfully with the popular VL53 ToF sensors connected to an ESP32. Report comment ...
