The full width will produce 5 volts, so this wave will produce 2.5 volts. Take note: Arduino has its own set default values of modulation frequency for its PWM pins. For pins 3, 9, 10, and 11, it is ...

AnalogWrite uses the various timers on an Arduino to put out a pwm waveform – with 1/256 (ish) resolution. And it offers 0% and 100%. This is naturally-available with the timers that the Arduino IDE ...

At the heart of the device is a AD9833 waveform generator; with the Arduino, rotary encoder, and 16×2 LCD providing an interface to control it over SPI.

Replacing that motor in this case is a brushless dc motor with its own three-phase drive box that can be controlled with a 5V pwm waveform or a 0-5V analogue voltage – It has its own 0V and 5V outputs ...

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 ...

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… ...
