Codes and resources for Arduino Workshop held by Prof. Prakash Dandekar at IIT Bombay - erciitb/Arduino-Resources ...

RGB LEDs are becoming increasingly popular due to their ability to emit different colors from a single LED. With the help of an Arduino Uno microcontroller board, you can control the colors of the RGB ...

The PWM sketch works to vary the output linearly, however, the light outputted by the LED does not change in a linear manner. When applying the scientific metric of ‘perceived brightness versus time’ ...

Pulse-width modulation (PWM) Pulse width modulation (PWM) is a powerful technique for controlling analog circuits with a microprocessor’s digital outputs. Pulse-width modulation,as it applies to LED ...

[Runtimemicro] has the answer, at least if you are writing PWM code for the Arduino. Their free application lets you set a few parameters, visually see the results, and then generates code for you.

In this project we use a popular JavaScript framework Node.js to control the LED connected to Arduino Uno. We will also use Node.js to control the brightness of LED from a webpage using Arduino.

A few months ago, [Julian Ilett] found a problem using the Arduino library for PWM. Recently, he revisited the issue and used his own PWM code to fix the problem. You can watch the video below.

With a 24V LED system garlands with fixed brightness, animate them with a controller for variable and random brightness with an Arduino.

Animate multiple 24 VDC LED garlands with flashing and variable brightness (13 different parameters) with one Arduino Nano multi-tasking with FreeRTOS.
