Project description
Supplies:
Step 1: Preparing the mini USB host shield to drive a 5V midi device
Step 2: Connect the Mini USB Shield to your Arduino Nano
Step 3: Chips, anyone? Added SN76489 with Osc 4 MHz. and shift register 595
Step 4: Just Add Code – Adding the Libraries, Compiling and Uploading the Code
Step 5: Connect an amplifier and speaker, connect your USB midi keyboard and test
Step 6: Complete the Circuit With a 5V Voltage Regulator, 12V Connector, Power On/off Switch and Power LED
Step 7: Box, Paint, and Enjoy Your New Synth
