Binary and hex converter: flip 8 bits
Flip 8 bits and see the number in decimal, hex and binary — plus the PORTB line to write it.

// HOW IT WORKS
The idea in 30 seconds
- Each bit is worth double the one on its right: 1, 2, 4, 8, 16, 32, 64, 128.
- Add the ON bits to get the decimal number. 8 bits go from 0 to 255.
- Hex groups 4 bits (a nibble) into one digit 0–9, A–F: 0b0010 0000 = 0x20 = 32.
- Shift left (<<) doubles the number; shift right (>>) halves it.
