I have an idea where I would like to build an auto leveling system for a table. I'm thinking on using an accelerameter to get it to level and then have it hooked up to motors that will get the table to 0 on the accelerometer.
Is this possible or is way to much work to even attempt?
Overall it possible. But devil in details. For example how accurate your leveling should be? How heavy is your table? How fast it should be leveled. How often you going to level it? etc...
So if very high accuracy is not required - simple accelerometer may do a job. But you need to find out what stepper motors and control boards you are going to use.
Do you have an Arduino already? Order an accelerometer module. Mount it to some platform. Run some simple sketch with output to serial monitor and check if you can get required leveling manually.
