Instead, we will use PWM to reduce the applied voltage. Sometimes you need to have greater control over the speed of your motor, which the Arduino allows you to do with the MotorSpeed sketch. Initially for a set of temperature the duty cycle is generated using PWM by varying the width of the pulse. The joystick (PS2 Joystick) consists of two potentiometers (one for the X-axis and the other for the Y-axis) and a push-button. 3 out of 5 stars 221. 1W - 130W Working current: Up to 3A Overcurrent protection: 3. Motor speed is determined by setting the duty cycle of the control signals. However, the code I provide here is full on and only about 40% off. The signal values that Arduino expects for the duty cycle is from 0 to 255 and it can be set by using the function analogWrite(pin, value). Whenever the button will be pressed on the android app, the Arduino will receive the data through the serial communication and will compare this data with the already saved in the data. Note that: we can use DC motor controller to control: DC motor with two-phase encoder. The enable/disable function of the motor control is signaled by Arduino Digital Pins 4 and 7.
