Electronic Drum Controller Will be Your Good Music Companion

If you a die hard fan of Drums, I bet you must be excited about this unique and DIY eDrum too.

The required components for this project:

  1. A PIC16F877 RISC microcontroller
  2. Two line (16×2) LCD with backlight
  3. Some amplifiers
  4. Twenty-two analog inputs
  5. Two digital inputs
  6. Twenty-two input gain potentiometers
  7. Four control buttons
  8. One MIDI out
  9. One serial RS-232 out

You need to remember the main goal for this project is to find and use the cheapest components, but can still be maintain results at the professional standard. By using the PIC microcontroller, the whole design becomes easier to expand and it’s also assembly language friendly as well.

Below is the list of eDrum special features:

  • 24 unique velocity sensitive trigger inputs
  • One Hi-Hat stereo input
  • One Snare Dual-Piezo input
  • Six Cymbal inputs with the choke
  • Four Mono Piezo inputs
  • Two modes HiHat pedal operation
  • One MIDI output
  • Four control buttons
  • The RS232 serial port
  • Assorted memory for snapshots
  • Various controllable parameters

Since this project is mainly about the Trigger to MIDI conversion matter, therefore the eDrum will not offer any other drumkits or sounds on it.
