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 ...

Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. Anyone interested in creating interactive objects can “play” with Arduino! Described ...

In the last installment of The GeekDad Arduino Guide, I introduced you to the Arduino hardware and why it is so cool. Now, let’s start actually using an Arduino. How do you get started? Well, first ...

Microcontroller port pins can typically be driven either high or low, or else be put into an "input" or high-impedance state. This circuit uses the three states to drive two separate LEDs with one ...

If you searching for an LED matrix for your next project or to add to an existing application you may be interested to know that the Maker LED Display is now available to purchase from the Crowd ...

When designing a handheld device with a colour display using white LEDs for backlighting, is it better to use parallel or series connected LEDs? Both architectures have their own advantages when you ...
