    Internship Design Project

    This project was intended for the spirit of Halloween, This circuit functions are meant to detect the movement of an object holding candies. If the sensor detect that anyone moves the object, it will send the data from the sensor to the microcontroller. Lastly, once the microcontroller receives the data, it will send it to the buzzer to output a buzz that will stimulate a shock.
