1. Servomotor controller (a) (10%) Set up a system that uses adjustable resistor to control the direction of servomotor. (b) (15%) Change the degree of servomotors direction from -90 to +90. Note: Do not set -90 and +90 only. You should deal with each degree, which means you should set the degree of servomotor according to the ratio of output of adjustable resistor to high potential. 2. Please implement a UART by using the keyboard to control Questionl's servomotor: (a) (5%) The CLI can show what you type. (b) (10%) Design a motor mode. Type "motor to enter this mode. In the motor mode, computer should show the value of servomotor's degree. Pressing e will allow you to exit this mode (C) (10%) Design a degree mode. Type degree to enter this mode. In the degree mode, we change the degree of servomoter through UART ranged from -90 to +90. For example, type 90 and press enter, the servomotor will turn to 90 degree. Pressing e will allow you to exit this mode
