xbee breadboard

One, what is "bread board"?1. Structure of bread plateThe breadboard is the "Integrated Circuit Experimental Board", which is a plug-in board, which has several small "sockets (holes)" on the board. In the circuit experiment, can according to the circuit connection request, in the corresponding holes inserts the electronic component's pin and the wire and so on, causes it to contact with the hole inside the elastic contact Reed, thus joins the necessa

On a, with GPIO direct power to the LED, with high and low level for switch, not reliable. A GPIO is a signal, not a power supply. Moreover, a GPIO can only give poor 5mA or so, take more will burn (I did not burn do not know if it is really going to burn, but the instructions above is written). This is not playing, so I did the following transistor experiment. 2N3904 parameters please click here. This is not recommended, LCM is 200mA, but I only have it, no way. Transistor, I use it as a switc

circuits you can simulate the hardware connection, writing and testing code, and so on, your Arduino also arrived, the code directly to the Arduino IDE to burn into the Arduino can be perfectly run, Ha ha. You can also share your results with your Autodesk 123D circuits to your friends for fun. First sign in to Autodesk 123D circuits and create a lab. There is only one breadboard on the inside, dragging an Arduino and an LED up from the component com

I love Arduino nano–. This is a very small but fully functional Arduino Uno. However, when I went to connect it to the Internet, all the neat and small also disappeared under the large-size Ethernet shield.However, I recently found a better, more compact way to connect my nano to the Internet – by using Wiznet Company's much smaller (and cheaper) Wiz550io module!If you want to make it easy to connect, you can find an adapter board that can connect to the module and Arduino Uno, but I want to kee

for the communication of the Arduino board."The Widgeduino provides two basic operating modes: widgeduino through the serial port: in the widgeduino application and the Arduino board between the serial communication. Based on a point-to-point (using RS232) or wireless point-to-multipoint (via Xbee 802.15.4). widgeduino Through the network: IP-based networking makes the internet of things possible. Such a pattern can also be used as a hy

Widgeduino-unveiled on Kickstarter recently-is a smart and easy-to-configure window-based on Microsoft Windows platform and Microcontroller System Communication applications based on Atmel-based Arduino board. Essentially, widgeduino communicates with the Microcontroller System through the serial port protocol or TCP/IP. "This includes, among others, keyboard, LED light, pressure gauge, knob, Slider, thermometer, container and button. the intuitive method is that communication simplifies rapid

history The appearance of the terms in News Archives suggests it might have been in common use as long ago as 1973.[2] One of the early definitions of the term "proof of concept" was by Bruce Carsten in the context of a "Proof concept prototype" in the column "Carsten's Corner ": Proof-of-concept prototype is a term that (I believe) I coined in 1984. it was used to designate a circuit constructed along lines similar to an engineering prototype, but one in which the intent was only to demonst
