Cabling is limited to the minimum thanks to the Grove open modular starter kits. For the die-hards there is the possibility to connect the screen to the Arduino using a breadboard and "real" wiring. As an aside, we'll demonstrate the use of keypads, which require additional libraries to be installed on top of the standard Arduino software. Furthermore, the somewhat more low-level components of the starter kit can be demonstrated, including buttons, temperature sensors and buzzers.
