Ultrasonic Sensor Walking aid 3DX
Description
My Wife Has A Tough Time Seeing. When We Are Out Walking You Have To Tell Her When There Are Steps So That She Does Not Trip Or Fall Down. Because Of This I Decided To Design A Handheld Device That Could Tell Her When The Ground Changes Either Up Or Down Using A Ultra Sonic Sensor And Two Led Lights. Red For Step Up, Yellow For Step Down. The Program Captures The Distance And Compares The Next Captured Value And Flashes The Appropriate Lights Or None At All. I Designed The Handle To Include The Battery, Found A Movable Sensor Holder That I Modified Some So That The Tool Could Have Other Functions If Wanted (Distance From An Object Id The First Thing That Comes To Mind. This Is Still A Prototype And I Will Be Working On A Better Version That Will Run On A Feather, Greatly Reducing The Size Of The Tool. Also Want To Modify The Code So That The Lights Only Flash When There Is A Specific Change In The Height (Like 1 Inch). You Will Need Support Material For The Front And Back. You Will Also Need To Print 2 Of The Rings.
