Simple Accelerometer Toy

Filed under: 8: State Machine,Assignments,Christopher Bridgman — cbridgma @ 11:34 am

So my idea for this state machine is to build a simple toy that uses an accelerometer to gauge how violently a toy is being played with. The idea is that, after you turn the toy on, the toy will go into attract mode, where it will blink an LED. Then, when the accelerometer senses movement, it will go into play mode, blinking multiple LED’s. Now the fun part is, if you shake the toy too violently and the accelerometer crosses a thresh hold, then an alarm will go off signaling the user to put the toy down or slow down. It is a simple idea, but i wanted to further explore an accelerometer while using analog input instead of digital input.
