Design a circuit to interface a $12$VDC unipolar stepper motor $($CT connected to GND$)$ that has a step angle of $90,$ and a seven$-$segment display of your choice to NI DAQ $6008.$ Show all connections in details.

$2-(12$ pt$.)$ For the circuit you have designed, write a Python code to run the motor two revolutions in the RIGHT direction, then half a revolution in the LEFT direction. While doing that, the step count $(1,2,...$ final step$)$ has to be displayed on the seven$-$segment display. Place your code in a loop so that this sequence is continuously repeated.
