Here’s an Arduino library that will let you drive a very large number of LEDs. [Elco Jacobs], an electrical engineering student, is the author of the library. He has a work-study job that has… ...

In this tutorial, T.K. Hareendran shows us how to set up an interleaved PWM output on an Arduino Uno. He then uses different techniques to validate that the desired result is achieve.

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’ ...

Community collaboration is a great thing. Take the Arduino PWM library for shift registers. Some folks at the Arduino forum pitched in and helped [Elco] trim off a bunch of clock cycles by using ...

When Timer/Counter1 is in PWM mode, the pins on the output of these registers go high when the count exceeds the register, and back low when the register cycles back to zero – either via a count of ...

In adding an alternative cutter drive motor (‘spindle’) to an existing cnc machine, an electrically isolated pwm to analogue converter is needed. The machine uses a ‘grbl’ controller, which has an ...

2. The Arduino PWM output OCRA charges the weighted-capacitor network, generating INT0 at the Schmitt trigger’s upper threshold of approximately 3 V.

Figure 1. Arduino 101* board with Intel® Curie™ technology ADC and PWM So, what does all this mean? To understand ADC and PWM, you first need to take a closer look at analog and digital signals ...
