In many projects presented in this blog I used the breadboard for prototyping and building the projects. Literally breadboard is mean a piece of wood (board) we usually use to cut the bread, this term later used by many of earlier electronics experimenters to descript the board they used to construct and connect all the electronics components on the piece of wood board. The breadboard has many advantages as it allow us to prototype the electronic design before going into the production and to reuse the electronics components for another project which of course will reduce the component’s cost especially for the electronics beginners.

Many times we need to quick wiring the electronic circuit on the prototype board (perforator board). One of the problems wiring this kind of prototyping board using the ordinary wire (PTFE insulated wire) is it become difficult and looks clumsy when the electronic circuit become complex, especially if we want to rewire the same terminal more than once.

Today you could easily find a decent quality DVD player for under USD 50; therefore many people just throw it away when it’s broken and just buy a new one instead of repairing it. But as the microcontroller and electronics hobbyist you would be amazed of how these junks could be become your home’s lab valuable asset and these electronics stuff perhaps worth almost USD 50 if you buy it one by one.

LED is used in many microcontrollers based project mostly as the indicator; by applying the right forward bias voltage to this special diode, it will emit the light. Today the used of LED has been tremendously increased not just as the electronic devices indicator but also for replacing the conventional light bulb (e.g. flash light, traffic light, car’s break/sign lamp, etc) and perhaps soon it will replace the fluorescent tube lamp in our house.

If you use a breadboard for quite a lot to develop and prototype your microcontroller’s based project than you will realize that we repeatedly use the LED to display the microcontroller’s port status. With more LED and its current limiter resistor being added to the breadboard, soon it will occupied our breadboard space very quickly, especially if we use small breadboard for prototyping; not to mention the wire we have to make for this LED and its resistor.

When a silicon diode is in forward bias, the voltage drop across the PN junction is about 0.7 volt, therefore this behavior can be used for reducing the 4 x AA/AAA alkaline battery (it’s about 6 volt) to power your Microcontroller project. (more…)
