Speed Control of DC Motor using Arduino In this circuit, for controlling the speed of DC motor, we use a 100K ohm potentiometer to change the duty cycle of the PWM signal. 100K ohm potentiometer is connected to the analog input pin A0 of the Arduino UNO and the DC motor is connected ...
When you rotate the potentiometer knob, the output voltage is changed, and the Arduino Uno reads this changing output voltage as the input voltage. And connected LEDs light up, and also brightness varies. After the above steps, your hardware is ready to use to control the LED brightness with...
Use the potentiometer to do one of the following projects: Controlling position of the servo motor.Hint: Refer toarduino - Servo Motor. Changing the brightness of LED.Hint: Refer toArduino - Fade Led. Additional Knowledge GND pin and VCC pin are interchangeable. The is no convention about the...
