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 ...

Step-by-step guide on designing and programming a custom I2C slave sensor device using Arduino. More for You. Who Won and Lost in Trump’s Tax Bill.

The analog sensor on the Arduino board senses the voltage on the analog pin and converts it into a digital format that can be processed by the microcontroller. Here, we are feeding the input voltage ...

[Johngineer] found himself in need of an I2C sniffer, but didn’t have one available. Necessity is the mother of invention, so he put together this I2C sniffer sketch for Arduino. The arduino … ...

Nice method and analysis. The temp sensor 3 pin devices are simple and cheap but good for 0.5 deg C precision or nearly a full degree in human measure.
