Counting with 0s and 1s

🔢 Computers store everything using just 0s and 1s! Turn 8 light bulbs on and off to add place values—watch 4 + 1 and parseInt("00000101", 2) both equal 5 side by side. 🔤 In Secret Message, turn 3 rows of bits into numbers, pick matching letters, and reveal hidden words! Pick the wrong letter and you get funny gibberish. 🎚️ In Bit Shift, solve puzzles to learn how shifting bits left doubles a number and shifting right halves it—moves are limited, so simple addition won't cut it. This app was made with code too · Remix it to create your own secret message!
