Help me out with Obstacle Detection
« on: September 06, 2008, 12:54:07 AM »
I m buildiing a computer controlled RC car..and i want to mount a obstacle detector on it and want the signal back to computer.

for this i am using IR sensor with 555 timer.but i m getting confused on how to get the signal back to computer as i dont want any wires attached between the car and computer.I m not using any uC.Also i want to mount a webcam on the car and video signals back to PC.Is there any means through which I can convert the usb webcam to a wireless one (bluetooth or wi-fi) ??

So how should i proceed.Do i have to use a uC ?? if yes which one will be easier to use.If any solution other than uC then it would be very helpful.

As for the camera, you can get ones with a built in transmitter that transmits to a reciever. The reciever can plug in directly to your TV (using the video ports), or you can buy a card for a laptop with the ports. The cheapest ones cost $50, I have one and the video quality is great. Google 2.4ghz wireless camera and youll find a ton of the $50 cameras to buy. If you want a little better quality signal you can get some cameras at www.rangevideo.com .

Well, you can transmit data wirelessly. But you'd either have to devise a circuit that transmits and receives the data, or use a microcontroller with bluetooth (or some other wireless method) to do it for you . . . I'd rather do the latter ;D

There are such uC... but I wouldn't recommend them since programming will eat up most of your time...
Although I know a IC that might help...
CYWUSB6935 from cypress semi...
Look here:
http://www.cypress.com/products/?gid=14&fid=65&GoGatewayCategoryID=All&

They sample their modules as well...
I got two...

Hard to work with chips but excellent in what they do... really....

If you need any help I have some ready basic code but also can tell you how stuff is going...

For whom the interrupts toll...


P.S. I've been inactive for almost a year... Don't give promises but I'll try to complete my tutorials. I'll let you know when..

Cheers!

I recommend just buying an external bluetooth transmitter and hooking it up.

For example:

Check out these goodies for transmitting discrete signals via RF.  I have used them.  They work great.

There is Arduino BT, I think Sparkfun has it...
Check out the uBotino robot controller!

In the second kit,is the bluetooth transmitter connected to the uC through USB ?

Nope, its directly connected by UART.

Only the computer is using USB for bluetooth.
