camera interface in MATLAB

this is the post explains about the how to interface  camera module to the matlab.

Here now i will explain how to connect the your webcam using matlab

by using this application you can do the many type of projects like 

1.security related

2.home appliance controling through the webcam

etc

C it is SEA

INTRODUCTION:

C is the general purpose programming language.developed by Dennis Ritchie.C is the facilitated to the strucutred programming language. 

Remote controlled Robo

This is the project where you want control the your devices with Remote it is very helpful.

introduction: This is the project explains about the how to control the robo using the TV remote.

for this project i used the arduino uno board ,tsop(ir remote receive),tv remote which is works like the transmitter.
simply arduino ide i used for the controlling the remote and arduino uno uno board.

connections:

1. Tsop is connected to the arduio pin 15
2. L293D which motor driver ic ,for controlling the dc motors to rotate in two direction  connected with micro controller digital pin (as your wish)

control system using the arduino with ADXL335

Hi these the project explain about the how to control the system using the ADXl335 3d mem sensor or motion sensor.

connections:

1.3 digital pins connected to the arduino to relay board

2.3 analog pins connected to the ADXL335

adxl335 gnd to arduino gnd

adxl335 vcc to arduino 3v3

concept:

using the adxl 335 we can control the system or device using the gestures

simply adxl 335 give the analog values that is connected with the arduino 

so simply arduno receive the values from the analog port by analogread..

by using your hand gestures you can control your home automation and industrial automation

code:

what is RISC

Reduced instruction set computing

RISC is abbrevated as reduced instuction set computing.
simply it is like a instructions how to use in the program.if you use less number of instructions not with complecated things then that is called RISC..

LM35(temparature sensor) with arduino

LM35 is the temparature sensor  it give the values those are the analog values .
here i connected the LM 35 with arduino on the analog port.
it is working properly and giving the values..
for pin discription see below the code.

/*

 VCC to arduino 5v GND to arduino GND

raspberry pi intro

The following tables give the mapping of the Raspberry Pi GPIO Pins to the GPIO connector in relation to the pin numbers and the physical location on the connector. This is a representation of the GPIO connector as viewed looking at the board from above, with the USB power at the top and the GPIO to the top-right of the board.

If using the connector pin numbering, then note that Pin 1 on the connector is the 3.3v supply. Pin 2 is the 5V supply, and pin 26 is marked SPI CE1 below.

P1: The Main GPIO connector:

wiringPi Pin	BCM GPIO	Name	Header	Name	BCM GPIO	wiringPi Pin
–	–	3.3v	1 | 2	5v	–	–
8	R1:0/R2:2	SDA0	3 | 4	5v	–	–
9	R1:1/R2:3	SCL0	5 | 6	0v	–	–
7	4	GPIO7	7 | 8	TxD	14	15
–	–	0v	9 | 10	RxD	15	16
0	17	GPIO0	11 | 12	GPIO1	18	1
2	R1:21/R2:27	GPIO2	13 | 14	0v	–	–
3	22	GPIO3	15 | 16	GPIO4	23	4
–	–	3.3v	17 | 18	GPIO5	24	5
12	10	MOSI	19 | 20	0v	–	–
13	9	MISO	21 | 22	GPIO6	25	6
14	11	SCLK	23 | 24	CE0	8	10
–	–	0v	25 | 26	CE1	7	11
wiringPi Pin	BCM GPIO	Name	Header	Name	BCM GPIO	wiringPi Pin

• Board Revisions: Please note the differences between board revisions 1 and 2 (R1 and R2 above)

P5: The auxilliary GPIO connector present on Rev. 2 boards only:

wiringPi Pin	BCM GPIO	Name	Header	Name	BCM GPIO	wiringPi Pin
–	–	5v	1 | 2	3.3v	–	–
17	28	GPIO8	3 | 4	GPIO9	29	18
19	30	GPIO10	5 | 6	GPIO11	31	20
–	–	0v	7 | 8	0v	–	–
wiringPi Pin	BCM GPIO	Name	Header	Name	BCM GPIO	wiringPi Pin

Note also that the P5 connector is designed to be used from the underside of the Pi – ie. you solder on the top of the Pi board to install the connector! If you are using it from the top, then you need to mirror the diagram above.

Each side has three columns. The outermost column, headed wiringPi Pin refers to the pin number in the wiring Pi code. The middle one, headed BCM GPIO refers to the pin number of the BCM2835 chip, an this is the pin number used when addressing the GPIO using the/sys/class/gpio interface. The innermost column, Name is the name of the function of the pin.

The central column contains the pin numbers on the header on the board. Pin 1 is the 3.3v power supply on the P1 connector (Rev. 1 and Rev. 2 boards), and Pin 1 is the 5v power supply on the P5 connector on Rev. 2 boards only.

Note: This page was edited (again!) on the 19th of June 2012 to fix the mistakes of the earlier edit. I have double-checked this against the schematic and by building a set of 15 LEDs and connecting it all up.

Raspbery Pi driving all 17 GPIO pins

The photo shows a static shot of a Raspberry Pi driving all 17 GPIO pins with LEDs. The program actually cycles up from Pin 0 to Pin 16 so I can check the exact pin ordering…
