Very cool!

Just brainstorming here but it would be great to have the larger one auto center when released (for driving) and the smaller one to stay where you put it (for pan and tilt). Is that possible?

Cool, thanks for your efforts. Right now the platform I have is a traditional RC chassis with steerable front wheels and 4wd power. I imagine using a tank control platform like this,

Would be easier.

Nice project. FYI, you can get cheap sbus receivers from Hobby King now. I have been looking for a similar solution. I want to convert the sbus protocol into a ppm signal. Does your project have that ability? If so, any idea of how much lag there would be?

Thanks

Well I don't have much programming experience so what environment do I need to use to modify the controls? Also, in searching for something like this, I read that dual inputs, like forward and left can be difficult to implement. Do you think that would be a problem? I am going to give this a try but I am sure it will be a slow process as I will have to learn the programming at the same time.

Thanks

Man this look exactly like what I have been searching for!

My plan is to have an internet controlled wifi/webcam rover to drive around the house/yard. My biggest issue was that I didn't want to have to install any software on the PC I was controlling it from. So, I plan to have a small PC on the rover with a usb video capture device with a camera connected and will stream the video via windows media encoder. I would have an arduino to handle the forward, backward, left, right of the rover with 2 more channels for the camera pan and tilt and a couple channels for lights, a video switcher etc. I wanted to have a website hosted on the rovers PC that would allow me to open a page with controls for the arduino and the video from the camera. This looks perfect!

Now for the questions;

1. So, how difficult is it to modify the Bitlash controls? Ideally I would like to have a virtual joystick, basically just a circle with a dot in it that can be dragged with the mouse for driving the rover. Like putting it in the top left would make it steer left while moving forward. Is there a GUI I can use to redesign the Bitlash GUI to be something like this? Do the controls act like a continuous input until released and "auto center" when released? If not, how hard would that be to program? I would want it to stop as soon as I released the slider/joystick or if there was an interruption in the connection.

2. Could the Bitlash webpage be hosted on the arduino itself like on an ethernet/wifi shield? If possible, I could use an RF solution of getting the video to another PC for the video encoding and not have to have a PC on the rover. Or maybe it would be better to use an XBee between the server and the rover/arduino and only have arduino, and XBee and an RF video TX on the rover.

I think there is a lot of interest in this and will be happy to post the final product/info for others to use.

Thanks!

Thanks for the info. I will check the voltage and the info on that page and report back.

Hello all,

This should be simple...

I want to use a arduino mini to take 4 channels from my RC receiver (pwm) and control a camera zoom, focus, etc. The camera has the leads that control the camera when grounded. so, if I ground one lead, it zooms in, another lead it zooms out, another lead focus near, another lead focus far etc. So, would I need to have relays for each lead or can the arduino short the leads to ground by itself? Anyone have a similar set of code to get me started?

Thanks

Thanks. That simple eh? So the serial communications going to the usb interface can be "tapped " into simply by connecting to the tx/rx pins? Very cool. That will make this project much simpler.

FYI: I am building a sentry turret and don't want to have the laptop physically connected to the device. I plan on making the turret mobile so this way I can reduce the weight etc.

Thanks again.

Hey guys, Brand new to Arduino here and am working on my first project. It requires a PC to communicate with the Arduino Uno via USB and it is working fine. What I would like to do is get rid of the USB cable and use 2 Xbee's that I have. I have an explorer regulated board and a USB explorer. Is it easiest to just connect the regulated explorer to the serial i/o tx/rx pins and power it from 5v? Or is it possible to simply plug the usb explorer into the usb plug on the UNO?

Also, once it is connected, what, if any, changes to the code need to be done? Do you have to specify to use the serial i/o tx/rx pins or is the serial communication already present on those pins?

Thanks
