I’ve always appreciated simulation tools. Sure, there’s no substitute for actually building a circuit but it sure is handy if you can fix a lot of easy problems before you start soldering and ...

This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer ... Do not power the ...

The end result is you can have the circuit simulator on the left of the screen and a Web-based Arduino IDE on the right side. But how does it work beyond the simple demo? We wanted to find out.

You can build an LED circuit fairly easily ... buttons, resistors, potentiometers, and servos to either a power source or Arduino. With just those components, you can already make a lot of ...

If you are designing your own intelligent “Graden Computer” with an optional digital plant moisture sensor/water pump controller that lights an LED to alert the user when it is time to water a potted ...

With small Arduino boards becoming more popular, Olympia Circuits is jumping into the ... switches for digital inputs - One thumbwheel potentiometer to introduce analog measurements and controls ...
