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 ...

This is a fork (backup) of the well-known "PWM frequency library" initially created by Sam Knight; see http://code.google.com/p/arduino-pwm-frequency-library ...

Arduino Due is an ARM controller based board designed for electronic engineers and hobbyists. ARM architecture is very influential in modern electronics, we use them everywhere like our mobiles, iPods ...

The creative adventures with ATtiny series microcontroller are awesome if you know how to play them. ATtinys — especially the ATtiny85s — are all around us, and by using one, we can shrink the size of ...

The DR44 is a two wire Alternator with a built-in regulator. Well, really three wire but the third wire is not needed if adapting this alternator into another vehicle. The DR44 needs a 5V, 128Hz PWM ...

Among all the Arduino boards, the Uno is most folks' go-to choice, and for good reason. It's the perfect platform to get started with Arduino, it's capable enough to handle a wide range of tasks, and ...

An idea in an earlier blog is to make a pwm interface that can accept 5, 12 and 24V pulse streams. That one uses a bunch of resistors and has three separate inputs. Below that, wise commenter DB ...

In this tutorial, we will develop a 5V variable voltage source from Arduino Uno. For that, we are going to use ADC (Analog to Digital Conversion) and PWM (Pulse Width Modulation) features. This ...
