The field of Haptic feedback has not yet been fully explored and utilized. Sure, your phone has several vibration profiles that might mean something to you. But Neil Movva is going far beyond that. His talk at the 2015 Hackaday SuperConference covers simple vibration motors, linear actuators, and going deep into vibration frequency tuning to trick the brain into feeling textures. He applied this knowledge in his Pathfinder project. It seeks to help the visually impaired better navigate and perceive their environment by pairing distance sensing with better haptic feedback.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
