This is the first time you've mentioned wheels.
Quote from: PeterH on Feb 23, 2013, 03:25 pmThis is the first time you've mentioned wheels.Sorry, I must have not been clear enough in my second post. So far I have developed a car that receives commands over a WiFi connection. I have Arduino Uno, Arduino WiFi Shield and a Motor Sheild (although this does not fit directly on the arduino). I have programmed Arduino as a server which takes commands from a client program. Everything works fine (move forward, back, left, right, all things that a car is expected to do). However the car is hard to drive when no longer in the same room That is why I thought of trying to plug in a camera.
isn't it possible to change the Atmel chip on the Arduino with another Atmel chip that is more powerful that has the same or possible to match pin outs (if exists)?
(I think RaspberryPI is too much for this type of project)
s it that impossible to transmit the captured video over the Wi-Fi through arduino - given the camera already captures the video?
Is it that impossible to transmit the captured video over the Wi-Fi through arduino -
Because the data rate of that video signal is far in excess of the data rate that the arduino can handle.
But it doesn't capture video, it capture snapshots.
It has a video output which you can connect to a screen.
NTSC is an analogue standard, that is connected to an analogue screen.What point are you trying to make?
Because it would need to convert that analog signal to digital?
Bingo! The ADC on an Arduino simply isn't fast enough, and there isn't enough fast memory to buffer an image anyway.Not only that, but to remove the redundant information (like JPEG does) to reduce the data rate out requires more processing power than the AVR can manage in a resonable time.
I assume there must be something (not arduino) which converts analog to digital.
If the video is already in digital format, would I be able to stream it over Wi-Fi using Arduino + Wi-Fi shield?
