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.
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!”
– A tutorial on the Arduino microcontrollers. The first chapter is here, and the complete index is here. ShiftOut. Learning Examples | Foundations | Hacking | Links Started by Carlyn Maw and Tom Igoe Nov, 06 Shifting Out & the 595 chip At sometime or another you may run out of pins on your Arduino board and need to extend it with shift registers.
.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.
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.
