DIY kit shield for the Arduino Uno. It turns the Uno into an 8-bit synthesizer with an audio engine based on the Atmegatron, now available with an enclosure
- 0.5 – 1 hour build time, depending on experience
- Soldering experience recommended
- YouTube tutorial to help building
- Once built the shield slots into the top of the Arduino Uno
- Powered by USB
- Audio via 3.5mm mono jack
Play
- 8-bit monophonic MIDI synthesizer
- Unique Wavetable PWM Synthesis audio engine
- Controlled via 2 RGB LEDs, 5 buttons and 6 pots
- Instantly playable using inbuilt sequences or play button
- A huge number of Atmegatron features in 1 tiny device
- Save sound to memory for future use
Hack
- Download the open source code from the downloads page
- Download the free Arduino development environment
- Upload the source code to the Arduino Uno and it’s ready to play!
- Tutorials and forums to help programmers
- MIDI hack your Arduino Uno and the miniAtmegatron becomes a MIDI instrument

Synthesis Engine
The miniAtmegatron synthesis engine is based on the Atmegatron engine, with some features cut back or removed because of the simpler interface. Like the Atmegatron, the mini uses the PWM output of the Atmega328P processor.
