The goal of the project was to move metallic checker pieces around the field using an electromagnet. The machine ended up resembling a simple 3D printer: 3 stepper motors, one moving base in axis X, two moving the head (magnet) in Y and Z axes. Software allows user to control machine manually and give simple tasks for automatic control (i.e. “move piece from A2 to E7”).
Software: Scratch for high-level control, Python for sending high-frequency PWM signal to GPIO pins.
