FYP Posted October 13, 2009 Report Share Posted October 13, 2009 Hi everyone, this is my first topic....and yes i need help :)I want to build a stick that can help the blind people while walking as my final year project.the idea of the project is simple, im going to use a sensor (IR, sonar, prox....etc) to detect objects (walls, stones...etc) and also to detect fire.so the sensor will detect an object, then it will send an amplified voltage to a microcontroller which will decide which sensor is active so it can send signal to the vibrator grabbed by the user.will im facing some difficulties to understand some basic things....what is the best (easy to use) sensor that can be used in this kind of project...where i need a sensor that gives a proportional voltage value with the distance of the object faced. remember that im going to program a PIC and i will include the maximum distance by evaluating voltage values with its respective distance.rang needed is around 1 to 2 meters only.please advice me, and let me know if u need more info'sthank you for helping Quote Link to comment Share on other sites More sharing options...
