DREAMWEAVER 4N

Hello! Welcome to the DREAMWEAVER 4N repo. The DREAMWEAVER 4N is an Open Source 4 Channel Sequencer or Arpeggiator based on the Arduino architecture. This is something that I have been working on for several months. If you have any comments or suggestions, I can be reached on Twitter @MakeAugusta.

Warning:

While, connecting external speakers to the IO port is ideal, if you use headphones DO NOT put those headphones on your ears. The output is too loud.

Programming the DREAMWEAVER 4N

Loading Software onto the DREAMWEAVER 4N

The DREAMWEAVER 4N can use the Ardiuno IDE to write software to it. The Arduino IDE recognizes the DREAMWEAVER 4N as an Arduino Nano. To set the Arduino IDE to load it change your board type in the Tools menu.

• Tools
  • Board:
    • Arduino Nano
  • Processor:
    • ATmega328P
