How to make a Smart Cane for the Visually Impaired with Arduino

I wanted to make something for them to help the visually impaired become independent, so I created an open source Arduino project for a Smart Cane. This Arduino smart cane can assist with walking alone in new environments by taking inputs through an obstacle sensor (ultrasonic sensor) and providing feedback to the person through haptics (vibration motor). Check out the video below for the demo and working. ...

LazyMax 1000: Arduino Phototransistor and Haptics Project

The idea for this Arduino phototransistor project came to me based on an idea that was shared by one of my friends at the FabLab. He talked about how his lab only has stools for people to sit on. Being very uncomfortable, the person succumbs to the discomfort and stands up to move around. In our case, we had very comfortable rolling chairs for sitting and reclining, which can get you lazy and even sleepy re ...
