For my third project build, I built a 16-step Arduino sequencer with a granular synthesizer built in to the device. The circuit and Arduino were code were from a SparkFun project page: here.

​

The goal was to design the case and housing for the sequencer and implement the Arduino into the system.

​

The right hand side knobs for the potentiometers control the granular synthesizer while the left hand side knobs control the sequencer. The buttons control the steps for the sequencer. Each step is set with a tone from the granular synthesizer. 

​

The 3D model for the sequencer was constructed in Solidworks. Next drawings were made of the front and back panels to provide a precise method for drilling the holes for the components. 

​

The outer wood frame was constructed with scrap wood and then stained. The panels used thin plywood and were painted black.
