Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

With supply chains breaking due to the pandemic, some resources are becoming hard to procure. There are cases when someone’s profession or life, depends on these resources. Being a technical author ...

When connecting a LED to a PWM Pin of the Arduino (3,5,6 on Duemilanove) and selecting "output default high/low" in the plugin, the pin can't be set or cleared. When setting it to "PWM 500 Hz" and add ...

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 the ...

Abstract: The light intensity controller automatically varies the brightness of an LED light depending on the natural light available in the room. In addition to this is room temperature and humidity ...

The goal of this project is to develop a signal generator using a microcontroller to create PWM signal via registers and give the user the ability to control the output of those signals via changing ...

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 ...

Abstract: This paper presents a simulation of a buck converter using pulse-width modulation (PWM) signal frequencies and duty cycles generated by an Arduino microcontroller for solar panel application ...
