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 ...

As difficult as it is for a human to learn ambidexterity, it’s quite easy to program into a humanoid robot. After all, a ...

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 ...

You can drive them directly from an Arduino or similar microcontroller using a library that converts an angle into a PWM signal on one of the output pins.

Aerotech’s XL4s linear amplifier for closed-loop servo control of voice coil and single-phase motors eliminates the nonlinearities common with PWM amplifiers.

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- ...
