Controlling LED brightness with a potentiometer - Daniele
Did you select the correct Arduino Chip in the IDE? Arduino maps pin 9 to a hardware pin (PB1 for UNO), which is not consistent between different boards; Try inserting a delay(100) after analogWrite(. . . ). I'm not sure if the analogWrite call restarts the PWM cycle, resulting …
The LED Fade Sketch for the Arduino - dummies
Arduino is a platform that can be used to develop interactive objects. For this project we will use the the Arduino Mega 2560. It has 54 digital input/output pins, of which 15 can be used as pulse width modulation (PWM) outputs. PWM allows the strength of the output to be varied. For example, to change the brightness of an LED.
Arduino PWM Tutorial - Arduino Project Hub
You will lean what PWM is and how you can get the PWM output from the digital pins of Arduino using analogwrite() function. Now let’s write a code to change the brightness of the LED using PWM. Arduino Code. Upload the code in the Arduino IDE and the LED will start to fade.
INTRODUCTION TO ARDUINO AND LEDS - School of Computing
I try to change the brightness of an LED following the formula in out1. I'm pretty sure that something is going wrong because it doesn't really change its brightness and it never stops lightening. It

Arduino and LDR controlling led brightness
Lighting an LED with a digital output pin is one of the simplest things you can do with a microcontroller, but how do you use pulse width modulation (PWM) to change the brightness of a LED. The answer to this question is very simple, so we’ll show you how to do this using the …
Arduino RC Circuit: PWM to Analog DC: 10 Steps
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.

Listing 2: Arduino using PWM to control the brightness of an LED. The Blink dim. pde program on the right hand side of Listing 2 uses the analogWrite function to supply a variable voltage level to the LED. 2 Example 3. 2 PWM Control of LED Brightness In this example, the brightness of the LED is set to three levels in an endlessly repeating sequence.
