WordBot

 

Build and keep your own robot that sends a secret message one letter at a time!

You will learn the language of robots, computers, and electronics – Binary (ones and zeros), so you can create the special code needed to display your secret message.  Binary can get very long with all those 0 & 1’s so you will also learn to convert binary to hexadecimal.

You will figure out how a seven-segment display works, and then wire it to a microprocessor and use it to build your robot!
