infrared sensors

I've got two sets of phototransistors and infrared emitters put together to make two IR distance sensors. They are both connected in the same way, both powered by my Arduino Uno, both with the same resistor, etc. But when I check the values I'm getting from them, one of them ranges from about 980 - 1010, with the higher value closest to the sensor. The other, however, goes from about 350 - 570, with the higher value the furthest from the sensor.

Computer On Wheels Controller

Hi guys,
 
 
 
Since last week, I've been learning c++ and openFrameworks and creating a application to control any robot with a computer on it or, at least connected to one by someway.
 
It is supposed to be simple to implement and use.
You just need to run the application and program your robot to read the following chars and act corresponding to them:
  • 'w' to move forward;
  • 's' to mo

Shooting mosquitoes with lasers

Straight out from Shoutbox I just snatched this:

Searhced around, and found this cool video of death!

Linefollower

Hello everyone. I'm trying to make a linefollower module, and I want to use it with a 28 pin project board (AXE020), but I've got some questions.  

  • If the module uses 5 of the input pins, one of voltage and one of ground, is it better to use a general voltage pin (the ones that are at the top of the input ones) or to use any voltage pin at the right of the used input pins?
  • If I need a voltage higher than V1 to power the module, can I take it from a V2 pin, or the signal sent by the module would be too high?

Thanks!

Motion Tracking from stationary observer

Hey guys..

I have an issue at my house right now...Young hoodlums of unknown origin have been sneaking onto my property and stealing things off my deck, and animals have been getting into my garbage.

 I want to build a robot that when motion is detected with a passive ir sensor, a webcam will activate and start recording, however I want the sentry to track the movement with some precision, since the target (hoodlum or rodent) will be of different sizes.
