Arduino
We used the Arduino Uno to control the SmartCane. The Arduino Uno is lightweight and versatile, making it the perfect controller for the SmartCane. The wide range of capabilities of the Arduino will allow us to add more features to the SmartCane in future iterations. Considering that this Arduino uses 5 volts to work it can easily be powered by a 9 volt battery. Ultrasonic Range Sensor Our sensor has a sensing maximum distance of 16 feet and has an accuarcy just over .1 inch. We do have limitations in our sensor due to the fact that it has a sensing window of 15 degrees. This limitation means that the objects that are outside of this wndow will not be detected and can present a danger to our user. This is definitely a point in which we plan to continue working towards improving. |
