I've found a circuit which uses PIC16F690. It is designed to display random texts stored in the PIC memory. Excluding the application mentioned on that website, what I felt is that we can use it during quiz programs for asking randomly chosen questions to the participants or as a dice in any game. I suggested it for one of my friends for his school exhibition. He modified the code and constructed it. Everyone liked it. But, his ma'am says its application is not that good. She's asking how this circuit can be used it daily life. Can anyone please suggest more applications.
