Micros pequeños, para Proyectos pequeños. Audio Amplifiers. Modest power audio amplifiers for driving small speakers or other light loads can be constructed in a number of ways.

Audio Amplifiers

The first choice is usually an integrated circuit designed for the purpose. A typical assortment can be seen on this National Semiconductor page. Discrete designs can also be built with readily available transistors or op-amps and many designs are featured in manufacturers' application notes. Older designs employed audio interstage and output transformers but the cost and size of these parts has made them all but disappear. Getting Started with Arduino! – Chapter Four. This is part of a series titled “Getting Started with Arduino!”

.NET Micro Framework – More blinking LEDs. Some time ago I wrote about FEZ Mini and FEZ Domino – first affordable development boards for .NET Micro Framework.

.NET Micro Framework – More blinking LEDs

Today I’m excited to tell you about another device called Netduino. Similar to FEZ Domino this board is pin compatible with Arduino, and therefore most of Arduino shields should work fine on Netduino. This makes transitioning your project quite easy.
