LOW COST AVR PROGRAMMERS

All of us can program a microcontroler – it's not a Rocket Science; all we need is an appropriate tool, or in this case a programmer device that is financially accessible. General disadvantage of these tools is that they can program only one type of microcontroller, but concerning the price, availability and your desire to get familiar with that particular types of microcontroller this is not such a big obstacle.

Ultrabright diode

LED emitt light when they are directly polarized. When the LED conducts, the electrones pass through the N-type material conductive zone to the P-type material conductive zone. Since the semiconductors of theP-type material conductive zone have less energy in contrast to the semiconductors of the N-type material, the energy of the electrons is emitted in the form of light.
