The same applies to the Arduino sketches related to the circuit. Last, but not least, this project can be used with other microcontroller boards with the same behavior described in the Arduino sketches.
This circuit can be considered as a general purpose daisy-chained parallel shift-out register group for a total of 32 output ports that we can easily manage with our Arduino board (or similar microcontroller boards), using only three I/O pins. The four capacitors between the GND pin of every device and the GND signal are designed to give more stability to the system, as suggested in the device data sheet.
Then you will find a somehow strange detail: a variable capacitor that can be optionally connected to an analog input of the Arduino. This part of the circuit is not directly involved with the logic of the shift registers, but as we consider to use this board as general purpose, it will be frequent for an analog value to be sent to the microcontroller - at least for testing purposes.
The kit includes:
The kit has been tested on many different Arduino boards, from duemilanove up to uno, mini, nano and Arduino-compatible boards.
