Birthday Wall

by NACK_YANG

Published on September 14, 2016

A wall that says happy birthday in lights while you sing.

Duration: 2.5 hours

How To Make It

STEP 1 : Birthday Wall

We drew out the word we wanted to have light up. Then we stapled light wires surrounding the letters. We used the sound sensor to make the wall light up when you are talking/singing.
