Here’s an Arduino LED backlighted sign I made.
(1) Arduino Nano – $16
(1) Bluetooth TTL- $10
(23) Addressable LED Strip (SMD5050/WS2801) – $20
Then some foamcore, paint, and hot glue.
I’m using a android bluetooth terminal program to send serial commands to the arduino. Right now the program just calls ‘Modes’, which are different effects I hacked together in the arduino IDE. Later I’ll write a more versatile program so you can more directly control the LED’s with an Android app or something.
FYI – The Q is for Quixote Studios.
