The project consist of creating a Smart cane for blind people and it contains three ultrasounds sensors, transistor to amplifive the corrent provided by the microcontroller, ad diode to control the electrical intensity direction, a capacitor keepingthe excess of curren for 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 the front side. All will be controlled by an Arduino and ESP32 microcontroller
