listening-step-sequencer

• adding sound level measuring to 'step-sequencer'

(Below is QUOTED from https://github.com/applecargo/step-sequencer)

step-sequencer

• a stepper driving sequencer
• programmable sequence
• for rapid prototyping involving stepper motors
• using 28BYJ-48 Stepper Motor with ULN2003 driver

schematics

• NOTE:
  • the 2nd/3rd wiring between stepper driver board and arduino, swaps!
  • i.e driver board pin 1/2/3/4 <--> arduino 2/4/3/5)
