Tap any letter or number to see its pattern and hear it. A dot is a short beep and a dash is a long beep.
A dash lasts about three times as long as a dot.
Start with the short codes: E is one dot, T is one dash, I is two dots, A is dot-dash, N is dash-dot, and M is two dashes. They appear in many everyday words.
Numbers 1 to 5 begin with dots and swap one dot for a dash each time. Numbers 6 to 0 mirror them.
