This is a story about creating a demo board for working with shift registers.

1. first create the circuit board
2. demo on Arduino platform as a single, 8 bit shift register
3. expand demo board to use multiple SR, iterative with software development
4. when hardware is operational port the software to STM8 platform and Cypress board
