-We studied the hardware interfacing of the ultrasonic sensors and now the software implementation of sensors. The basic working of the ultrasonic sensor on SJone board is just the dealing with sensors. Sending a pulse from one pin to the trigger pin enables the triggering of sensors. Then the return pulse from the echo pin is detected using the interrupt functionality on the interrupt port 2 of the SJone board.
+We studied the hardware interfacing of the ultrasonic sensors and now the software implementation of sensors. The basic working of the Ultrasonic sensor is sending a pulse from one pin to trigger pin, which enables the triggering of sensors. Then the return pulse from the echo pin is detected using the interrupt functionality on the interrupt port 2 of the SJone board.
 The major part of this implementation is timer. To calculate the time between the pulse send and pulse receive, timers are used. When a trigger pulse is sent to the trigger pin, the timer is started and when the reflected pulse detection is sent from the echo pin to the interrupt pin, the timer is stopped. This time difference is the time difference between the pulses. And applying the time distance equation to get the distance is the final motive.

 We tested this module by giving different values to the the waveform register and observed the following patterns.

 During testing of the project, we had to take care of one basic thing, that is we checked all connections properly. We tested the Haptic Driver implementation independently with different vibrating pattern based on obstacle detection and the distance of the obstacle from smart stick. During testing we got to know more and more conditions that would affect our implementation and then we included all of them one by one and eliminated the limitations of the project.

 == Conclusion ==
 We decided to make a stick for blind smart, for which we decided to use heptic sensor which could be integrated with the distance sensors to provide the feedback and connect to vibrators which would eventually help the blind person to know in which direction the obstacle is. At the same time, we also came up with a challenge to detect the floor which would also be required for blind person to be able to fully trust his stick. Since we are five members in our Simpsons team, as other add-on features we decided to include GSM module through which the blind person can send SMS whenever an emergency arises or he panics to his friend. Other feature that we have included is a key locator that will help blind person to find his useful keys by pressing a button from his stick. <br>
