Control 28BYJ-48 Stepper motor with hand gesture using Arduino

This video shows you how to control stepper motor with the gesture of your hand. Rotate it clockwise, counterclockwise, or stop it.

This video shows you how to control stepper motor with the gesture of your hand. Rotate it clockwise, counterclockwise, or stop it. Must watch this two videos 1-Stepper motor Watch Stepper motor 2-Gesture sensor Watch Gesture Control You will need to download the Gesture sensor library from GetHub
