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 ...

A lot of great ICs use I2C to communicate, but debugging a non-working I2C setup can be opaque, especially if you’re just getting started with the protocol/bus. An I2C bus scanner can be a he… ...

Arduino Setup For this experiment it is necessary to download and install the “Arduino I2C LCD” library. First of all, rename the existing “LiquidCrystal” library folder in your Arduino libraries ...
