Binary Bracelets

Ada Lovelace, the first computer programmer, wrote computer algorithms for early computers, huge systems of gears powered by a steam engine! To talk to these machines, she would use cards with holes punched in different places, to communicate to the computer which gears it needed to turn.

Modern computers store information in bits, which use binary, a different way to represent numbers and letters. Check out this activity to create your own beautiful, binary bracelet with a secret message written in the language of computers!
