Insight Did Your Cling or Table Fan rotates slowly than before Here Circuit Diagram To control the direction, set IA and IB to different logic levels: IA = HIGH and IB = LOW for clockwise rotation. IA = LOW and IB = HIGH for anticlockwise rotation. To control the speed, apply a PWM signal to either IA or IB while keeping the other pin at a constant logic level.
A few seconds after the upload finishes, the fan runs at full speed for 4 seconds, then the fan will reverse at a slower speed for 2 seconds and then stop. Manually control the rotate direction and speed of the Mini Fan. In this example, we use a potentiometer to control the speed of the motor and a push button to control the direction.
Comprehensive Guide to Centrifugal Fan Rotation Circuit Diagram
If you power the Arduino UNO module, the servo motor will start to totate and the Fan module will start to spin, you can adjust the fan speed with a potentiometer. Watch the video for the detail demonstration. Congratulations! You have completed your project with Visuino.

Once the motor is easily accessible, you'll want to use a screwdriver to rotate the fan's direction switch, which is usually located at the top of the motor. This will change the fan's direction of rotation. Once the direction switch is properly adjusted, you'll be able to reattach the fan blade and then reinstall the capacitor.
How Do You Reverse The Direction Of An Ac Fan Motor Circuit Diagram
The motor rotates in a certain direction with the value of Speed. Experiment Summaryยถ In this experiment, you can also control the motor to rotate or not. Just connect pin 1, 2EN of the L293D to an I/O port of the control board. Set 1, 2EN as High level, and the motor will start rotating; set it as Low level, it will stop the rotating.
