How can I use xbee to transmit the data from a cat 5 cable? Answered

I want to wirelessly system link me and my friends Xbox.  I believe since it is Xbox I would only need four wires from the cable, the data1 - and +, and data2 - and +.  Is this true?  If so how many xbees would I need?  If not, how could I do this?

Arduino xbee coding using 2 button as transmitter and 10 led as receiver?

 For the turn signal code, there is a receiver and transmitter  For the transmitter code, I want to set 2 button  When I trigger left signal , Left LEDs will turn on and press again will turn off  When I trigger right signal , right LEDs will turn on and press again will turn off  When press both button both signal of LEDs will turn on and press again will turn off  For the receiver, I would put 5 LEDs on the left and 5 LEDs on the right  The light would turn on when the buttons are trigger, to have left, right and stop signal I want to code to be quite similar like https://www.instructables.com/id/turn-signal-biking-jacket/step5/sew-on-your-turn-signal-LEDs/ but not using arduino lilypad but arudino uno and xbee Does any one know how to do this coding and schematic, please help thanks!!

Arduino Xbee's only communicate with another Xbee connected to your computer? Answered

I guess I just haven't looked into this very far, but I thought Xbee's could communicate with a wireless router.  So basically, for an xbee to communicate with the cloud my computer needs to be on with another xbee plugged into it?  And if I want constant communication, my computer needs to be on 24/7?

How can I sense the movement of my two cats throughout my house, easily and cheaply? Answered

I want to be able to detect where my two cats are within my house using an Arduino and some sensors. Accuracy doesn't need to be 100%, as long as I know which room they are in or which side of a room, that will do. I thought of using RFID tags and readers, but I would need one reader per room or area and they are very expensive. XBEE triangulation is a possibility, but this also sounds expensive and not sure of teh size of the devices the cats need to carry, I then thought maybe an IR lamp on the collar and a sensor in the room, but this requires a lot of power meaning a bulky pack on the collar, which I don't want. Final idea is maybe one cat has an IR reflective patch on the collar and the other a UV reflective patch and an IR and UV sensor in each room that sends out a flash of IR and UV every 10 seconds or so. But not sure if this is safe and if it can be done. So..... I'm looking for ideas from the community. It must not cost a lot. The cats mustn't need to carry anything bulky. The devices need to be wireless. Any ideas please? Thanks, Mike

how to connect arduino to a webcam?

I made a robot that moves using arduino controlled using Xbee(zigbee) connected to my PC and i put on the car a robotic arm to grape any object i like , but after that i wanted to make it much more harder to make the robot find that object using a webcam but i dont know which program to use and how to make an interface between arduino and the used program

Wireless LED light?

I would like to make an LED light that can be controlled by some form of wireless on/off switch. I cannot use IR as the switch will be in a different room to the light. I think I could use the Imp board I have seen on here but that seems expensive as I think I would need 2 Arduinos, 2 Imp shields and 2 Imps. Maybe I could use Bluetooth, Xbee or RF? Any thoughts? Cheers. Phil

I have ESCs with mode Linear; can I use them for my motors?

I recently bought 4 ESCs for my 4 brushless motors. THe ESCs are 20Amps. However, I found out that they have BEC mode linear and I might need an external BEC to power my receiver. Now my question is; lets say I am not using a receiver, I am using xBee mdules, which are going to be powered by arduino. Do I still need the BEC? Also, how would I power the arduino which needs 5Volts. Do I put a seperate battery for it?

Proximity Shirt

Is there a project on the site that duplicates what the two proximity shirts do that were sold on thinkgeek? Locked-on proximity shirt: http://craziestgadgets.com/wp-content/uploads/2010/02/proximity-sensing-shirt.gif Zelda hearts proximity shirt: http://www.thegreenhead.com/imgs/proximity-based-dynamic-life-shirt-3.jpg I am not trying to make my own shirts but I am interested in the tech that makes those two shirts work. If the same results can be duplicated with an ardurino and/or xbee, then that would be great!! Please let me know if that can be done and if yes, could you point me in the right direction. Thanks!

Nama: a project on design/art/technology.

Hello all! Some time ago I visited this forum and took lots of doubts regarding an ongoing experimental project. I would like to post the results of this work bellow: Nama, my graduation project on design/art/technology. A study about contemporary aspects of language and the sensitization of movement in search of a personal unique creative pulse. http://viraseres.com/nama/ Videos: Interactive Installation: http://vimeo.com/viraseres/nama Experimental interface for movement: http://vimeo.com/viraseres/nama-instrument There's also a recently Instructable of the interface that I made: https://www.instructables.com/id/Nama-Instrument-10/ The full concept and development documentation is available at the website, together with a DIY tutorial of the interface, and the open source files of the generative audiovisual installation. Feel free to send me feedback, critics and opinions. Thank you all for your help!
