PWM (Pulse Width Modulation) - PPM-dat

What changes:
👉 Pulse width (duty cycle)

What stays fixed:

Frequency

Pulse position

|■■■■■■      |  60% duty
|■■■         |  30% duty
|■■■■■■■■    |  80% duty

Used for

• SMPS regulation
• Motor speed control
• LED dimming

boards

• SCU1063-dat

• SG3525-dat - MSP1046-dat

  /* Fade

  This example shows how to fade an LED on pin 9 using the analogWrite() function.

  The analogWrite() function uses PWM, so if you want to change the pin you're using, be sure to use another PWM capable pin. On most Arduino, the PWM pins are identified with a "~" sign, like ~3, ~5, ~6, ~9, ~10 and ~11.

  This example code is in the public domain.
