Summary
- Each digit of the number pi has been assigned to a servo motor under ardunio control, allowing the robotic hand to ‘write out’ the digits of pi one at a time, in celebration of Pi Day.
- However, as the robotic hand only has five ‘digits’, any numbers higher than five require two ‘digits’ to be displayed.
- The hackaday.com readership loves the build, but have suggested some improvements including binary mode and ASCII mode.
