Circuit Walker Sneakers pt. 1: Accelerometer Filtering w/ Tony D!: A New video by Adafruit Industries
Circuit Walker Sneakers pt. 1: Accelerometer Filtering w/ Tony D!
Live stream to http://ift.tt/1RCEQ5c showing part 1 in a series to build step-reactive light-up Circuit Walker Sneakers with Circuit Playground. Using the accelerometer and NeoPixels built into Circuit Playground classic and express you can build sneakers that light up with each step. This first video looks at the step detection algorithm and how to apply filtering to accelerometer values for basic step detection.
