1. Sketch a full bridge driver circuit using PFETs and NFETs connected to a motor, indicating the current flow for forward motion and the logic state of the FET inputs.
2. Calculate the speed of the stepper motor on the mechatronics board in rev/min if it is driven at a rate of six steps per second.
3. Derive a formula for the output of the temperature sensor on the mechatronics board, in the form V=f(t).
4. Suggest three disadvantages of using the 3.5-digit parallel LCD compared with the serial alphanumeric display described in Part 2.
5. Write a statement to display the number ‘8’ on digit 1 on the mechatronics board LCD, and explain the meaning of each element of the statement.
6. Describe briefly the hardware ...
