I'm working on making an automatic seed sowing machine.
For that i would like to introduce a system in which the farmer would have to input their field size and then the machine automatically starts to cover the whole field.
For example if i input 100 (rows) x40 (colums) as my field size then the machine should go 100 units in the forward direction then take a u-turn and come back 100 units and continues to do that untill it finishes all the 40 colums.
For this i was wondering, what type of device should be used so that the farmer can input the field size into it and it could forward that value to arduino which would in turn guide the motors to move for that specific distance.
I'm a bit confused myself so i couldn't explain it better then this, please ask question if you don't understand what I'm trying to say.
Ps. I would be needing help with the coding as well.
