14. How to control DC motor speed ? H-bridge DC motor dir pwm POWER V motor 0 1 t T .T (1 -  ).T Pwm T is the period. T is the period. The duty cycle (  ) is generally given in percent. The duty cycle (  ) is generally given in percent. For a power supply of U volts, V motor = .U. For a power supply of U volts, V motor = .U. from microcontroller

15. RC Servo Motor 3 wires: power, ground, control Control signal sets the position. High pulse every ~20 ms determines set angle; pulse width between ~0.5 ms and ~2 ms, indicating the two ends of angle range Internal gearing, potentiometer, and feedback control.
