EarPrint Technology

As we all know that finger print have been used by the government and other security agencies so far to identify the people. Many government Agency holds millions of finger prints in their database. But, fingerprint can be damaged with calluses.

Scientist from University of Southampton do research and develop a new technology named Ear Print Technology. Ear identified by using Computer Vision to convert human feature into IDs.Scientist use this technology to design image ray algorithm which identify the human ear with 96.66 percent accuracy.

This technology will going to replace the finger print technology in near future.It is more accuracy than any other method.

SMPS of computer

fig:- working principle of SMPS fig :- SMPS of computer From the above figure, we came to know that the function of SMPS in computer which is to convert the high 220V-AC to 0-12V DC.SMPS contain several color of wires which carry the different voltage to the different parts of the computer.The following table shows the different color cables and its carrying voltage.

Multiple mcp23017 interfacing with Arduino

MCP23017 is the I/O port extender that runs on 12C. It is 16-bit I/O expender.in this tutorial we are going to interface the single and multiple mcp23017 with arduino. fig:- mcp32017 module IT has 16 I/O ports from PA0 to PA7 and PB0 to PB7. first of all we are going to interface the single mcp23017 with Arduino. For this connect the circuit as shown on figure. Download the library for mcp23017 from sketch-- include library -- manage libraries.
