Скачать или смотреть SPEED CONTROL OF DC MOTOR USING STM32 BY PWM TECHNIQUE.

To control the speed of the DC MOTOR interfaced with STM32 (blue pill) by PWM (Pulse Width Modulation) technique. For our project we are using STM32F103C8T6, LCD, ULN2003IC(motor driver IC), 2 10k Potentiometer, Proximity sensor, DC motor, 9V Battery, led, resistor, capacitor.ULN2003IC(motor driver IC) is used to drive the motor in one direction. We are going to take analog value from ADC pin i.e. PA4 pin of STM32 which is connected to the center pin of potentiometer and then convert the analog value into digital value format. The digital value is further provided as PWM output to control speed of DC MOTOR. By varying the potentiometer the speed of the DC MOTOR can be varied.
