The project consist of creating a smart cane for blind people and it contains three ultrasound sensors, a transistor to amplify the electrical intensity provided by the microcontroller, a diode to control the electrical intensity direction, a capacitor keeping the excess of current from the three vribration 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 the front side. All will be controlled by an Arduino or ESP32 microcontroller.
