HI ALL..
im new in this forum... and i want to learn about arduino..
never use it before..
btw, i am a final year student in mechatronic eng.. i need to create a LUX METER USING WEBCAM as my final year project..
but i have no idea how to make it.
can u all help me?
im very2 need your help.. anything can reply at this topic or send to my email.. zulfadhliahmad@yahoo.com..
**sorry for my broken english..
Arduino is not powerful enough to handle the data stream of a webcam. Try an embedded Linux platform as the Raspberry Pi or OpenWRT (with USB capable devices).
owh... i never use an embedded linux ... is it like a matlab,microcontroller?
From the programming side it's a full-fledged OS like a PC (which may run Linux too 
). You have processes, multi-tasking. What's often missing is a memory management unit so you have to take care about memory usage as with a microcontroller. But usually you have much more memory, more flash (often SD cards) but less GPIOs and ADCs (that's not a fixed rule). It's harder to do real time programming (guaranteed response times) but much easier to access PC peripherals like webcams. Theoretically you can run matlab on it but it's much better performing when programmed in C/C++ (or any other language compiled to native code).
