An Arduino robotic drummer

A funny hack for carnival 2015

This is an automated, self playing drum machine, which can play an external midi source or preloaded patterns. It uses door lock actuators cause it's strength, low cost and enduring

You'll find all project schematics and code in https://github.com/nliaudat/robot-drummer

Functionalities :

Infrared remote control to setup (speed, riff)
25 preloaded riffs, based on ascii drum tablatures
Possible Midi source (not yet available cause Bluetooth module is not finished, midi source is working on lab)
LCD display
RGB ledstrip synced with music
Each hit can be set as loud or normal

Hardware BOM :

Drums

Hi-hat (with pedal)
Bass drum
Snare drum

Electronics :

4x 12V Door Lock Actuator (2.8$ x 4)
1x 8-Channel Relay Module (3.3$)
1x Arduino Mega 2560 (7$)
1x LCD Display Module [1602] (2.15$)
1x Infrared Remote Controller Kit (0.7$)

Optional :

5V Voltage regulator (DIY manual included in Fritzing schema) (0.5$)
RGB led strip (5$) (!! Do care : some are +12V and other -12V)

Usage :

Plug a 12V battery (cheap chinese lithium are available under 50$)

Construction :

"Img_Vid" folder for hardware
"Arduino" folder for logics
"Fritzing" folder for wiring and electronic bom
Relays and isolation considerations
Voltage regulator (optional but recommended)
