Q5. Propose the H/W and then write S/W for controlling temperature inside oven (800-260) based upon the rotation of stepper motor. Suppose that there are the directional steps of stepper motor control four heating coils. 1. If the direction of rotation is forward, temperature inside oven will increase by connecting a coil that has higher thermal energy than one before. 2- If the direction of rotation is backward, temperature inside oven will decrease by connecting a coil that has less thermal energy than one before. Stepper motor positions against temperature levels of each coil are: position 11H Step 1 2 3 4 22H 44H temperature 80=050H 140=08CH 200=0C8H 260=104 88H
