Turns a fraternity/sorority paddle into a music and lights show!

Musical Paddle

This program was built to turn my Kappa Kappa Psi (honorary band service fraternity) paddle into a music and lights show that would play our school's fight song, "Buckeye Battle Cry," using an Adafruit Trinket 5V (ATtiny85 @ 8MHz). The MusicalPaddle.ino file also contains code to play "Hang on Sloopy," but it was not used in the final project.

This project would not have been possible without the TrinketTone code by Bruce E. Hall, W8BH. http://w8bh.net/avr/TrinketTone.pdf

Hardware used

• 1 Adafruit Trinket 5V
• 2 5mm Standard blue LEDs
• 1 5mm Standard white LED
• 1 Toggle switch push button
• 2 330Ω resistors between board and blue LEDs
• 1 1KΩ resistor between the board and the white LED
• 1 Passive buzzer
• 1 9V battery
• 1 9V battery snap connector
• Hook-up wire
• Solder

Move pitches folder to your Sketchbook's libraries folder

In order for the pitches.h file to work, the pitches folder must me moved inside of your Sketchbook's libraries folder before compiling.

Why didn't you use the built-in Arduino tone() method?

The normal Arduino tone() method does not work with the Adafruit Trinket, so some TrinketTone code by Bruce E. Hall, W8BH that gives the same result with an Adafruit Trinket was used instead.
