Sense The Tilt

SRJT10104

Jugaadu realized about his teacher's tiring job of board erasing again and again. He thinks of some solution which could automatically erase the board for his teacher. What could be it? Think!?

We can start by creating an Arduino UNO based Bot mechanism using triple axis Accelerometer sensor. As soon as the sensor senses the tilt, value of resistance changes about 3 axis which is read by Arduino UNO. Arduino UNO will give its output to Motor Driver which will cause movement of the bot.
