"Potentiometers are incredibly useful, whether you’re controlling the volume on your stereo or the ‘mood lighting’ in your room. The problem with traditional potentiometers is the fact that your microcontroller doesn’t have an easy way to interface with them. Digital Potentiometers solve that problem by allowing you to control a voltage splitter with digital signals. Wire it up just like a potentiometer and use serial signals to ‘turn the knob.’ Another...

"This is a glass ferrule type fuse. It fits great with our 5mm fuse clips. The fuse is rated for 125VAC, up to 5A. Fuses are pretty simple, if more than 5A pass through the fuse, the small filament inside the fuse heats up and breaks (like a light bulb burning out). The circuit is then broken and hopefully your circuit is saved from molten destruction. For smaller loads, you may want to checkout a PTC (aka resettable fuse) listed below. These handle less current (500mA) but can be set and...
