The wiring method
uses a single-chip microcomputer to control the motor rotation wiring method. The wiring method
for controlling the motor rotation using a single-chip microcomputer isFigure1.6shown in. The power supply of the MCU is connected to theof the drive moduleCOM; thePWMpin is connected to theof the MCUPWMoutputfor speed regulation;IN1andIN2 areconnected to the twoMCUIOs of theto control the motor to reverse and brake;5VOcan providefor the MCU5Vpower.
Use the button to control the motor forward and reverse wiring method.
Use the built-in control motor to reverse the wiring method asFigure1.7shown in. Among them,PB1andPB2are two buttons. WhenPB1 ispressed andPB2 isnot pressed,IN1is high,IN2is low, and the motor is rotating forward; whenPB2 ispressed andPB1 isnot pressed,IN1is low andIN2is high. The motor is reversed; when bothPB1andPB2are bounced, bothIN1andIN2are low, and the motor brakes(or brake).
