    I've been what I'd term a 'dabbler' or 'tinkerer' with electronics for many more years than I'd care to remember, but I'm no 'expert' by any means, but over the last few months, reading of Paul and Colin's exploits with the Arduino micro computer has made me wonder what I'm missing (apart from my marbles!:avatar:)

    So, after some deliberation, I've ordered one of the various Arduino experiment kits, basically an Arduino mounted on a circuit board with the ability to connect various supplied sensors to the inputs, indicators to the outputs, then I can have a play around and maybe learn a bit more about Arduino's, although understanding the programming side is likely to be my "Achilles Heel". At this stage, I'm not really sure what, if anything, I might eventually use Arduino's for on the layout, but I just think it's something I ought to get to grips with......wether I keep my sanity with this is debatable, and since it just uses a 12 volt supply, I'm unlikely to take out the local electricity substation, but here goes.......

    Ooops! I blame Paul, myself being an innocent bystander and all that...:giggle:
    Here's to Dabbling and Tinkering :thumbs:

    My work is done

    12V is at its max end, 5V is optimum - so a usb / phone charger will be perfect, just need to up the current if you are going to go above 3 servos.

    But while your developing your program, the arduino will be connected to the PC's usb port and will take power from that.

    Look forward to seeing the fruits of your studies

    Download fritzing to do your circuit diagrams.

    I'm teetering on the brink too.... I'm thinking of using one to run my turntable.
    .. and besides... it sounds like fun!

    Well, it's arrived! Now comes the fun bit (or alternatively, the 'headbanging' starts!):avatar:

    I'd be a bit wary of the m?m sign Keith could be trying to tell you something

    Nice ...

    The SDA and SCL ports on the upper Right hand side you will find useful in the future, these give you access to the I2C bus, which you can add additional devices

    For example LCD display fitted with an I2C interface board

    http://www.ebay.co.uk/itm/Serial-IIC-I2C-TWI-2004-204-20X4-Character-LCD-Module-Display-For-Arduino-Blue-/262317442560?hash=item3d13568600:g:BxwAAOSwubRXLALb

    or

    servo boards - 16 servo's per module.

    http://www.ebay.co.uk/itm/PCA9685-16-Channel-12-bit-PWM-Servo-motor-Driver-I2C-Module-For-Arduino-Robot-/161880925589?hash=item25b0dae595:g:F~QAAOSw7hRWPYim

    You can have multiple modules on the bus, one module is master (normally the arduino) the others are slaves. The interesting bit is another arduino can be a slave, and the same interface is on a Raspberry Pi.

    Enjoy ..... :avatar:

    Hi Paul.
    Meant to ask you, what the heck is "Fritzing???'
    Sounds like something you might do if you dropped the hot soldering iron onto the dog!:avatar:

    Got him now - there is no escape :avatar:

    http://fritzing.org/home/

    Fritzing is a opensource hardware design application for electronic projects.

    Price - Free

    Allows you to create circuit designs on the PC, in either Stripboard, breadboard or PCB formats.
    For example my arduino servo board, I just add the components to the stripboard, until I have them where I need them, cheaper and easier than cutting breaks, only to find I need to chang a components position.

    I normally start with the breadboard layout, and build up the project on my bread board, once completed and tested, I then re-create the project on to the stripboard layout.

    I'm guessing this isn't what Paul means by 'breadboard'... :scratchchin:

    Working on the problem Ian

    Got the first one Helga wants a Polony Supper

    2nd One and a half Normans = Harold and the invisible man

    but
    3rd Norman + Helga = Harold and the invisible man (but not sure if that is before or after the polony supper

    4th When you loose an electron, your Iron battery is flat

    5th half a norman plus his Uncle is equal to Barry white and whoever else can fit in the room

    Simples :avatar:
