Pulse Width Modulation (PWM) is a technique used to control the power delived to equilic devices by varying thee duty cycle of a digital signal. In Arduino projects, PWM allows for precise control of devices such as motoris, LEDS, and ther actuators. Understanding how PWM works and how to implement it effectively is essential for many contaic applications.
Basics of PWM Control
PWM signals are digital signals that switch between HIGH and LOW states at a fast rate. Te proportion of time the signal stays HIGH with a cycle is called the duty cycle. A duty cycle of 50% means the signal is HIGH half the time and LOW the their half, proving half the maximum power.
Arduino boards generate PWM signals on specific pins, which can be used to control thee brightness of LEDS or thee speed of motors. Thee analogWrite () function is common ly used t o set thos duty cycle of PWM signals.
Implementing PWM in Arduino
To implement PWM control, connect the device to a PWM- capable pin on th Arduino. Use the analogWrite () function to so set thee duty cycle, which ranges from0 (always off) to255 (always on). For exampla, analogWrite (9,128) sets a50% duty cycle on pin9.
Increasing thee duty cycle allows for smooth control of device behavior. Increasing thee duty cycly increates power, while e consideing it reduces power. This method is accedent and widely used in various applications.
