Preview one breadboard usage picture first.  And you can learn how the pins connected in one breadboard and how to use it.  The following is some basic information about breadboard. What is a breadboard? A breadboard is a rectangular plastic board with a bunch of arrayed tiny holes in it. You can easily insert electronic components into these holes to make up a connective circuit for prototyping or testing. There are different sizes and different colors of breadboards like these. You can visit this page to purchase breadboards in good price.

Voice typing feature is quite common to mobile phones; it is considered faster and user-friendly to those who find it difficult to type to input the question about which they need information. If typing fast is required or your handicap, this feature works the best for you. In this article, we will input voice via an Android App and the output will be displayed on LCD using Raspberry Pi. This requires a 16x 2 LCD with Raspberry Pi which is equipped with Bluetooth to receive inputs from the mobile phone. Start with Connecting 16x2 LCD with Raspberry Pi: Setting Bluetooth is preceded by interfacing 16x 2 LCD with Raspberry Pi. Bluetooth setup, first we will interface 16x2 LCD as Raspberry Pi accessory. External

1. Avoid the input end getting too close to the output end, especially in the case of high gain. For the following reasons: 1) When it is a positive amplifier, being too close would generate the parasitic capacitance - positive feedback loop – then cause the shock; this shock is independent of the input signal, that is, it could happen without input. The frequency of this shock depends on the circuit structure and parasitic capacitance and other factors, most of the time it’s over 1MHz. However, with the changes of parasitic capacitance, what would be caused is not only the circuit shock, sometimes the situation of work instability and deterioration would happen. 2) When it’s the opposite amplifier, the Miller effect is generated, which would cause the deterioration

At this time, I guess that you are enjoying your vacation, spending happy and leisure Christmas time with your family. Nowadays, Christmas is very popular even in China. Lots of stores are decorated with Christmas trees, beautiful glass stickers and flashing bulbs. And children might had simple accessories, like wearing a Santa hat or reindeer antlers headband.  Among some business promotion, people   dressed up as a Santa, and gave away small Christmas gifts. In some live show, girls performed in sexy Christmas  costumes  to increase popularity. Elecrow is not an exception, we made a splendid Christmas trees, and hanged our wish cards on it. And our company also prepared a surprising gift for all the staff. [caption id="attachment_4379" align="aligncenter"

PCB world is really magical and broad for makers to create various useful projects. As we know, it is a board that has lines and pads to connect various points together and sort of like a layer cake for its  laminated substrate,copper,soldermask and silkscreen together with heat and adhesive. Nowadays plenty of makers are paying more attention to the design of PCB. They would like to make PCB this dull thing filled with innovation and creativity to satisfy people's fancy demand. So it comes to today's topic: How To Create Circuit Boards For Unique PCB Design? Here are two main methods for unique pcb design: Special silkscreen layer arts& Shapes custom.
