Use the PWM feature on the microcontroller to drive the Hitec HS-311 hobby servo motor shown in E8.5. The control signal is for this servo motor is a PWM signal (5 volts) at frequency of 20-60 Hz. The pulse width of the control signal, which ranges from 0.7 to 2.4 ms, controls the position of the hobby servo. At 0.7 ms, the servo is at one extreme of its motion range, while at 2.4 ms it is at the other extreme. At 1.5 ms pulse width, the servo is in the center or mid-position. This servo has a motion range of ± 90 °. Use the rotary pot to adjust the pulse width (or duty cycle) setting of the control signal. When the rotary pot is at one extreme of its travel, the pulse width setting should be 0.7 ms. Turning the pot clockwise from that position should increase the pulse width setting. When the rotary pot is at the other extreme of its motion, the pulse width setting should be 2.4 ms. Implement an infinite do-loop to read the desired pulse width and to adjust the duty cycle of the PWM signal (use PIN #3 for PWM). Add a small delay (100 ms) in each run through the loop.
