Arduino Homing Device Prototype

A prototype "homing device" built using an Arduino microcontroller board and an XBee radio transceiver for about $60. Here I'm testing the range up to about two blocks from my house showing the LEDs respond to distance from the radio beacon.

Phil - I used the standard XBee - surprised by the range I got - above advertised, but more-or-less line of sight.

hi dmoralesnava - are you able to set AT commands? That would suggest you're connected and the modules are working. I followed specific instructions in the "Making Things Talk" book by Tom Igoe and Make Magazine - worth the purchase and should help.

[dmoralesnava]

Yeah, i'm able to set them, i even set MY and DL parameters and also i set RO = 0. I'm sendeng bits through DIN and i'm excpecting to recive them through DOUT (in the other XBee, of course). Do i have to send bits according to the BOUD parameter i previously set? i mean, if i have BOUD = 9600, does frecuency has to be 4.8 KHz? i'm using UART protocol. My XBees are serie 1

I don't have my AT commands handy, but if you're able to talk from PC to xbee for both devices, then you shouldn't have to worry about baud. Make sure both xbees are assigned to the same LAN ID (you need to do this manually) and that when sending serial data from your xbee, you're using broadcast mode or your're addressing the other xbee's ID directly. Outlined in detail in MTT.

Didn't he say he didn't have a battery pack for the handheld wow that's a long extension cord.

This works similar to Spiderman's spider tracer! lol

Now you need to grab a magnet and attach it underneath the bosses vehicle.

would be cool if it showed the direction to the beacon

[skierplaterandy]

so if it was going between 1 and 0 bars you would still be able to transfer data?

could you use this in an rc car/plane?

u can like give the othre one to ur son so if he get lost u can track hi measily lol
