Waiting to get mine, but for usb serial from picaxe to a wifi device, the TP-Link WR703N looks good, available shipped from dealextreme for $23.90US here: It's also available on ebay.

Here’s the idea: A sharp GP2D12 IR Range Sensor on a mini servo, with positional feedback and a scanning routine. The scanning routine must sidestep the conflict problem with SERVO commands and serial TX commands. The positional feedback must be accurate and repeatable, and hopefully easy to implement without requiring addition sensors/encoders. The Picaxe, hopefully an 08M ultimately, though I’m prototyping with a 14M, will operate independently of the main robot ‘brain’ and send object detection and ranging data serially. This is what I have so far: The scanning routine simply lets the servo go as fast as it can on each sweep. Without a delay in the loop, the available ram will be full with readings before the sensor head has panned more than a few degrees. This works upto a point, but the problem is that no two servos are exactly alike, and even a single servo will vary it’s sweep time according to battery conditions etc. Picaxe 08M with optical sensors/slotted interupter [Archive] - PICAXE Forum - Nightly.

Hi, Im trying use an optical sensor as an input to my picaxe 08M, for some reason i can not seem to get it to work, even without the picaxe, I have choosen to use RS part number: 497-5576. this can be seen at rswww.com From what i can gather is a photo diode and an infared diode in the same package, and should always remain high unless the beam of light is blocked in which it should go low.

I;m trying to make it work on 5 volts as this is what the picaxe uses as its supply voltage, I have used a 220ohm resistor into the LED as a form of current protection and thus giving the led 20mA (Approx). Is there any way to connect a picaxe board to the net? help! WinPicProg Page. Connecting a PicAxe to a wifi router [Archive] - PICAXE Forum - Nightly. Thanks for the links, Hippy.

Interesting that the IBM token ring was actually configured in practice as a star - ie the same physical config as cat5/6 routers. A real ring uses the least amount of wire, but it is harder to add nodes to if one has to take one's soldering iron up into the roof etc. It is a pity that bidirectional RS232 to Cat5 converters are not cheaper, as it is possible to pick up a second hand 12 port cat5 router for $5. For non time critical sensing, token ring probably is well worth looking at. For up to about 10 nodes, a single wire-or bus may be easiest as long as the bus spends most of its time inactive. Controlling Picaxe microcontrollers with a computer or let them communicate. On general demand (ok, Fritsl asked me...), I will show and explain you how to let several Picaxe microcontrollers communicate with each other or how to control a picaxe microcontroller with your computer.

This is actually fairly easy with the serrxd and sertxd commands. Serrxd reads the serial in port and sertxd writes to the serial out port. Now, when you check the Picaxe manual for these commands you will see this: Syntax:SERRXD (qualifier,qualifier...)SERRXD (qualifier,qualifier...),{#}variable,{#}variable...SERRXD {#}variable,{#}variable... What this means is: Qualifier: when this is used, the Picaxe will wait until it reads the value that has been entered as qualifier and then continue with its operationVariable: b0... you know these ;) Little example: serrxd ("LMR"),b1 will wait until it reads the letters LMR and then put the first byte after thos three letters in b1.
