Code

Automated_chessboard

arduino

Code will: *Home magnet with end stops at position A1. *Receive square address (Letter, Number) from Serial Monitor for piece to be moved. *Translate input into number of steps to be completed by stepper motors. *Receive square address (Letter, Number) from Serial Monitor for new piece location. *Turn on electromagnet. *Translate input into number of steps to be completed by stepper motors. *Turn off electromagnet. Notes: *Stepper motors will run simultaneously (during zeroing and moving with the magnet off ) until one reaches its max steps and then the other will continue until it reaches the specified square. *When the magnet is on and moving a piece the steppers initially offset to the corner and moves along the line between squares to prevent pieces interfering with each other. For example, this allows someone to move their knight before moving the pawns in front of it.
