I built a binary counter with Arduino! 🔢 Each LED represents a bit (0 = off, 1 = on). The Arduino increases the count step by step, and the LEDs switch on/off in a sequence that shows the binary number. For example:
000 → 0
001 → 1
010 → 2
011 → 3
… and so on!
This is exactly how digital counters in computers work—they increment values automatically, storing numbers in binary. Such counters are used in everything from digital clocks ⏰ to microprocessors 💻.
