    AFAIK The USB-Serial conversion takes place internally to the main chip so there isn’t a point where you could cut some serial data tracks and solder one in

    The sparkles are only designed to work on the D output.

    I’ve no idea how on earth they could be working from A B or C on the Crumble Robotic Vehicle!

    The Crumble is a simle single board controller that can control 4 input/ouputs and 2 bi-directional motors as well sa up to 32 sparkles (special RGB LEDS)

    It can be programmed using its own Scratch like language and is intended for use in schools/code clubs and homes

    it is plugged into a computer (PC or MAC) via USB and can be used to switch LEDS on and off /read switches without any other power supply

    To run motors and other add-ons – a 3xAA battery pack is needed.

    The hardware is propriety

    best way to find out about them is to buy a starter kit

    First thing is to goto control panel>sysntem>devices and see if you can find the malfunctioning device
    try and remove it

    Then unplug and reboot and plug bak in again

    By LEDS you mean sparkles?

    They are directional so make sure your connected D on Crumble to left-hand side on sparkle marked ->D->

    As well as connecting + and – from the ones at the top of the Crumble near the USB socket

    Simon

    PS Are you able to get the little motor LEDs working OK just to check that your Crumble is working?

    My TMP36 came and I can confirm it can be used with Crumble 🙂

    @nooodle What’s a “k-type” probe?

    I’ve just ordered a couple to see if they’ll work with the Crumble 🙂

    The DS18B20 needs special code to read its output as it send the temperature in a digital format (known as 1-wire)
    Something like https://www.sparkfun.com/products/10988 should work as it produces a analog voltage output but I’ve not tried one myself

    What sensors are they?

    One thing – pressing stop, halts the program but doesn’t switch off the sparkle. I don’t remember whether previous version did or not but I think good idea if it does

    Well basically I’m a die hard Scratch 1.4 person from the early days.
    Also, not a fan of online Scratch 2.0 (any online system is bound to fail at the most inappropriate time 🙂

    And offline Scratch wants to either update Air or itself every lesson and is therfore a pain in the neck to use practically.

    And then Scratch say that they are ditching support for the current method of offline extensions so that’s another problem 🙁

    And ScratchCrumble is an fork of my ScratchGPIO for the RaspberryPi

    To address the bespoke commands issue, I’m developing using BYOB (the Scratch 2/Snap pre-cursor) for that purpose

    I didn’t go do the BYOB route with ScratchGPIO as it needs more CPU power than the original Pi could give but now that Pi2 is here – its where I’m planning on going.

    I might develop Scratch 2 extensions if more demand but I’m only at the late beta stage with ScratchCrumble and not tested it yet in real classroom use.

    Finaly caveat – the libraries ScratchCrumble needs are currently not open-source so it would be hard (mabye impossible) to develop Scratch 2 extensions at the moment (I’m not a Scratch 2 extension expert but that would be my guess)
