"Dits and dahs" are the sounds created by Morse Code. Dots, of course, are the dots of braille. Learn all about Morse Code and the braille code--and try a little coding yourself! This hands-on program takes place at APH with a visit to the nearby Thomas Edison House. The event is free, but space is limited, so registrations are required. Call 899-2213 or email firstname.lastname@example.org by November 15 to register.
