They also only implement serial sending (so the Arduino receives) so far, although they mention the next step would be to build the other side of the connection. They say the data transmission is ...

We were most familiar with the CTS, or Clear to Send pin, on the serial side of things. When this pin is active, it indicates to the host that the attached device is ready to receive further data.

Here, the Arduino microcontroller serves as the bus master, initiating all data transfers and generating the clock which regulates the flow of data. The serial device 24C256 present on the bus is ...

Serial Plotter is an amazing tool available in Arduino IDE (from v1.6.6) to visualize the “returned” data beyond just seeing numbers spit out onto the traditional serial monitor window. The Arduino ...
