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

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’ ...

The duty cycle of PWM (and therefore LED brightness) is calculated by scaling a 0 to 3.3 V input voltage, set by a potentiometer connected to an analog input pin. The blink interval is fixed and has ...

[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.

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 ...

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.

4×4×4 LED Cube Arduino Code Explanation The code is structured to perform a sequence of predefined lighting patterns, creating an engaging visual experience on the 4x4x4 LED cube.
