Smart cane project

The project consist of creating a smart cane fro blind people and it contains trhee ultrasounds sensors, a transistor to amplify the corrent provided by the microcontroler, a diode to control the electrical intensity direction, a capacitor (condensador) keeping the excess of corrent from the three vibration motors. The samrt cane vibartes in a proportional way deppending of the distance of an object and detects objects located on the right side, the left side and the front side. All will be controlled by an Arduino or ESP-32 microcontrler Neocities.
