Design and code a circuit that has 5 slide switches as inputs and a push-button. When the button is pressed, the circuit will drive a stepper motor n-steps in the clockwise direction, where n is the 5 bit two's complement number input on the slide switches. If the two's complement number is negative, it turns in a counter-clockwise rotation. The seven-segment display shows the number you entered as a signed decimal number, and this display should count down (towards zero) as the motor steps.
