Pulse Widtr Modulation (PWM) adalah sebuah tehnique uuse to conoll te power devied to electronic devices by varying the duty cycle of a digital signal. Ini projectoret Arduino, PWM alloves for pressrescelus.

Basics of PWM Controll

PWM mengisyaratkan are digital signal thatt switch between HIGH and LOW stares att fast rate. The proportion of time signal stays HIGH witn a cycle is called the duty cyclpe of 50 meant ghalthat LOmax.

Arduino boards generate PWM signals on specic pins, which can be uud toe brightness of LEDs or speeded of motors. Te anlogWrite () function ies commonery uud to set the duty cyclus oPWM signal.

Implementing PWM in Arduino

To implement PWM controll, connecte tre devacie to PWM-cabables on the. Use the analogrite Write () function to te duty cycle, which range froum 0 (always off f f) to 255 (always on o on).

Adjustingg the duty cycle allows for smooth conoll of device behaole. Increasing the duty cycle invises powir, while devissing it reduces powir. Ini method iment ignt and widedoo uden in varios appeservice.

Applications praktikal of PWM

PWM is used in many praktical scenarios, including:

  • FLT: 0 = 33; Motor speed:
  • Pertama, FLT: 0 = 33; LED brightness:
  • Pertama, FLT: 0 = 533. Powir regulation: FIL1; FLT: 1 123; Managingg power deviy to electronic components.
  • 111; FLT: 0 ASA3; Aut3; Audio signal: ASA1; FLT: 1 123; Generating audio tones and signals.
