How to send "Happy Birthday"
By sound
Say it in rhythm: four dits, dit-dah, dit-dah-dah-dit, dit-dah-dah-dit, dah-dit-dah-dah — pause — dah-dit-dit-dit, dit-dit, dit-dah-dit, one dah, four dits, dah-dit-dit, dit-dah, dah-dit-dah-dah.
By light
Flash HAPPY in five groups, take a long word-gap pause, then flash BIRTHDAY's eight groups. It's the longest phrase here — keep your speed steady so you don't rush the ending.
By tapping
Tap it out on a table as a birthday surprise; the double P in HAPPY and the T-H pair in BIRTHDAY are the parts to practice first.

Party surprise. Flash it with a phone light during the birthday song for a nerdy-cool twist.
Social media posts. Post the dot-dash string as a caption; Morse enthusiasts in your comments will decode it.
