Power to achieve 78-series chips +5 v and +15 v for motor speed control pwm wave way, the pwm pulse width modulation to change the duty cycle for 51 single-chip.

Power chip +5V 78 series, +15V on motor speed control using PWM wave, PWM is pulse-width modulation, achieved through 51 single-chip computer to change the duty cycle.

The power source uses 78 series chips to realize +5V, +15V selects the PWM wave method to the electrical machinery velocity modulation, PWM is the pulse width modulation, changes the dutyfactor realization through 51 monolithic integrated circuits.

Power supply with 78 series chips for +5, +15 V V on the motor speed, the wave form PWM PWM is pulse-width modulation, by 51 one-piece for the change.

Power chip +5V 78 series, +15V on motor speed control using PWM wave, PWM is pulse-width modulation, achieved through 51 single-chip computer to change the duty cycle.
