accelerometer problems

(1/2) > >>

ok so im clueless ive built a large a symmetrical robot and im using 2 24vdc motors with a 2x25 sabertooth motor board and arduino uno. i want my robot to self balance but im having trouble finding a good accelerometer i was gonna use sparkfun's 5dof imu but they stopped making it then i was gonna use arduino's 5dof and they ran out of them and havent made more. ive been using manny tutorials because im clueless and really this is a huge step ffrom what i usualy build so i need help. these are the tuts iven been working from to piece together my bot http://www.instructables.com/id/SITWAY/?ALLSTEPS http://www.instructables.com/id/Self-Balancing-Scooter-Ver-20/?ALLSTEPS. i was using them to get the large motors to work because all the other tutorials were for direct motor conection with small motors then i found this one http://www.instructables.com/id/Self-Balancing-Segway-Instructabot/?ALLSTEPS he uses this http://www.robotshop.com/en/sfe-3g-tripleaxis-accelerometer-breakout-board-adxl335.html will this work for me? my robot is built like the sitway but is wired like the self balancing robot but with a 2x25 this is way over my head but i keep pushing forward i need help

Also check at Adafruit for accelerometer and other sensors.

The currently best bang for the buck in accelerometer/gyro boards:

You can find a compatible board on eBay for a fraction of the price, if you'd rather send a small amount of money to China than support the Sparkfun company and community.

but will this work for my purpose? like i said i dont understand accelerometers at all i dont know how they work

One reason for supporting Sparkfun is that they give you information like this.
