Your codes. In this activity, you will understand how Pulse Width Modulation (PWM) works and how it can be used to control the brightness of an LED using the analogWrite() function in Arduino. You ...

Note that humans perceive the brightness change non-linearly. The human eye responds to light in a logarithmic fashion and has a better sensitivity at low luminance than high luminance. If you do not ...

/* serial_pin_control_with_breathing - take commands from serial and light or extinguish leds based on it Demonstration of taking serial commands while doing something else. */ int max_led=7; int m ...

You can fade out and fade in the light of an LED automatically by using Arduino and a simple code that is described below. Even though the Arduino board cannot output variable voltage on its digital ...

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...

If you've got an Arduino of any variety, you might have noticed some of the pins on the board have a tilde mark or PWM printed next to them. What is PWM?
