Connecting and reading USB Webcam with Arduino?

-

hello everyone,

i have old usb webcam, wanted connected arduino mega board. want read , store data output in file on pc using serial port or sd card.  cut off usb connector , got 4 wires: 5v, data-, data+ , gnd. connected d- tx , d+ rx of arduino board.

my questions are:

1- possible do?

2- correct connection?

3- how can read data output of webcam? format?

4- there protocol needed connection?

i'm open suggestions,

appreciate help, answer :) 

no, not stands.  wires supposed connect usb port.  furthermore camera behave usb slave device.  arduino mega behave usb slave device.  won't able communicate each other on usb.  (one device has host work).

you around slight hiccough getting usb host shield, still tiny step towards solution.

the next issue have webcams not equall.  why can't have 1 driver fits in windows.  within windows bad enough low level details of how particular camera communicates, going more trouble worth.  involve extensive research , endless hours of perseverance stage can start communicating it.

alas after effort you'll realise sram on arduino mega can't hold single image camera, it'll next useless.

add fact final solution work exact camera , technical details you've gleaned along way won't portable.  i'd project non runner.  sorry :(

hello, first post asking in forum patient if dont correctly   well, im trying make robot evades obstacles , uses interrupts in order distances. ive used flexitimer2 run void function each 5ms, problem whe try verify program says me there error in use of flexitimer.    code: [select] flexitimer2::set(1, 1.0/1000, rastreodistanciamin()); i copy code below, please can tell error , how solve it, ive been loking dont know do. thank you code: [select] #include <flexitimer2.h> #include <servo.h> //motor a int ena = 7; int in1=6; int in2 = 5; //motor b int in3=11; int in4=10; int enb=9; servo cabeza; //hc-sr04 device int echo = 13; int triger = 12; //it use hc-sr04 determine , return distance in front of him int calculodistancia(){   volatile int tiempo;   volatile int distancia;   digitalwrite(triger,low); /* por cuestión de estabilización del sensor*/   delaymicroseconds(5);   digitalwrite(triger, high); /* envío del pulso ultrasónico*/   delaymicroseconds(10);   tiem

LED Strip Code

i downloaded code. here have several single leds flashing music microphone. in project, instead of single rgb leds, have 5 rgb led strips. need change in code? led strip 10m supernight rgb strip cut 5 equal strips. // arduino pin numbers const int do_pin = 2; const int ao_pin = 0; int sound; int led1 = 8; int led2 = 9; int led3 = 10; int led4 = 11; int led5 = 12;   void setup() {   pinmode(do_pin, input);   pinmode(led1, output);   pinmode(led2, output);   pinmode(led3, output);   pinmode(led4, output);   pinmode(led5, output);   serial.begin(9600); }   void loop() {     if (sound > 31) {     digitalwrite(led1, high);   }     if (sound < 31) {     digitalwrite(led1, low);   }     if (sound > 35) {     digitalwrite(led2, high);   }     if (sound < 35) {     digitalwrite(led2, low);   }     if (sound > 40) {     digitalwrite(led3, high);   }     if (sound < 40) {     digitalwrite(led3, low);   }     if (sound > 45) {     digitalwrite(led4, high);   }     if
