A hardware implementation of the classic interview coding problem, written in C and targeting Atmel ATTiny85. Endlessly looping around from 1 to 99 and displaying the loop value on two 7-segment displays while lighting up two LEDs (Fizz and Buzz) when the loop value is either a multiple of 3 (Fizz) or 5 (Buzz), or both.
