PURPOSE: A braille learning apparatus using iron balls and a piezoelectric element is provided to facilitate a braille learning process by stimulating the curiosity of users. CONSTITUTION: Input data is transferred to a piezoelectric element and a micro controlling unit using iron balls. The piezoelectric element senses the input data based on the weight of the iron balls. The input data is transferred to a computer through serial communication. The computer verifies the input data based on a program using a monitor, a speaker, and a concave and convex part. |
