Smart cane project

This project consist on creating and samrt cane for blind people and it contains three ultrasound sensors, a transistor (to amplify the current provided by the microcoontroller), a diode (to control the electrical intensity direction), a capacitor keeping the excess of current from the three vibration motors. The smart cane vibrates in a proportional way depending on the distance of and object and detects objects located on the right side, the left side and in the front side. All will be controlled by an Arduino ESP-32 microocontroller.
