I picked up a Memsic 2-axis accelerometer from the sensor drawer at radio shack. I’ve never used an accelerometer before and this one uses MEMS technology. I hooked it up to my BS2-IC via breadboard and uploaded a maze game.
My next goal is to write C code for it using the AVR libraries and integrate it with my robot. I am thinking it will help with pathfinding as well as being able to tell when my robot is stuck on a chair leg or something.
