Auto Leveling Laser Cross

Step 11: Using AutoLevel Fixture & Conclusions

Attach the base to a tripod.

Manually adjust the stepper motor screws so that the top board is fairly level with the base.

Adjust the tripod so that the top looks fairly level.

Make sure the rocker switches are all up.
Plug in the AA batteries into the Arduino.
The program should adjust the steppers until the top board is level.
Then it will turn on the laser.
After runtime (15 seconds), the laser will briefly shutoff to check the calibration.

Conclusions: Well the fixture does what I expected it to do. It’s not too reliable. Sometimes it tries to adjust past where it should and I have to push the reset. It could probably use some work in the sketch and maybe the electronics. But I am Lazy and probably won’t do any more for now. Still it was a good learning experience in utilizing an accelerometer and ‘automated’ feedback.
