This project controls a tea brewing process using an Arduino. It includes a menu system operated via a joystick, a relay to control the heating element, and an LCD display to show the status and ...

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 ...

Only two wires can be used from the microcontroller while the I2C bus can handle up to seven I2C LCD interfaces. An Arduino, Microchip PIC or any microcontroller with built-in or bit-banged I2C ...

[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 … ...
