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 ...

To regulate the brightness level of an LED with PWM, just connect it to one of the PWM channels (with a 1K resistor in series) and use the “analogWrite” command to control the duty cycle, as shown in ...

Most projects are built on abstractions. After all, few of us can create our own wire, our own transistors, or our own integrated circuits. A few months ago, [Julian Ilett] found a problem using th… ...

If you've got an Arduino of any variety, you might have noticed some of the pins on the board have a tilde mark or PWM printed next to them. What is PWM?

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… ...

Majority of these applications require precise motor control of servo motor. The architecture of current controller of servo motor is given, as evident from previous work.

Capable of operating as a position, velocity, or force/torque mode amplifier and controller, the VCA 100 module is designed for use with the company’s linear and rotary voice- ...
