Churchill ? (His mother was a American.)

She was born an American but became British on marrying her British husband.

No, it was Shaw.

77  Using Arduino / General Electronics / Re: 4 connector LED glows with skin resistance but not with current from ARDUINO UNO. on: August 16, 2014, 08:17:11 pm
Are these tricolour LEDs?
Are these opto-isolators?
Why have they got 4 pins when normal monochrome LEDs need only two?

As Robin 2 hinted, half an hour with a pencil and paper writing a list of all the states your system can be in will save you from 'spaghetti code' and much associated angst. Also look up the switch-case construct. Within each state, you set the lights for that state and wait until the time has elapsed, before moving on to the next state.

Any pumped system will, of necessity, leave your bottles open to the atmosphere and, therefore, ingress of dust and evaporation of the alcohol.
With optics, the bottle is sealed at all times except when dispensing. This allows no evaporation and, as the inflow of air is upwards, little chance of dust entering the bottle.

Do they still teach Icky Thump in Lancaster?
1) That's 'Ecky Thump and
2) It's Yorkshire.
Are you trying to restart the war of the roses?    smiley

The mantle has been passed, Mike, a long time ago.
Whether some of you guys can get that isn't my problem.
Oh you colonialist do make me laugh.

Here is a documentary about it
Was it Churchill who said that we are two countries separated by a common language?
83  Using Arduino / General Electronics / Re: Bread Boards & wishful thinking? on: August 15, 2014, 08:50:04 pm
What would you ask of a Bread Board, other then 'better, tighter connections'?

 USB in/out?

 What would be your dream development 'Bread Board'?

Much more area.  Like a table-top.  3+ voltage rails, not just two, and bench supply
built in with multiple isolatable areas.  Failing a table top then a large brief-case
for portable demos.  Various goodies round the periphery is always nice, but
area area area.

Oh yes, 6 contacts per strip, not 5, of course.
If you're going that big, why limit it to 6 terminals? 10 would be better (5 for thin wires, 5 for thicker wires).
I'd include a built in multimeter, transistor tester, loudspeaker, battery holders of various sizes (for when you're not near a mains outlet) and a variable power supply. Also handy would be a set of compartments to hold components (some lined with antistatic material).
When you've added all those, you'll also need a crane to lift it.   smiley
84  Using Arduino / Programming Questions / Re: How to use Interrupt() corretly on: August 15, 2014, 08:23:48 pm
If your wheel is turning at less than 1,000 RPM you don't need to shouldn't use interrupts. Just count the number of pulses in a given time and multiply by the circumference of the wheel. Look up 'state change detection'.

Yes it is brown gravy.
I think the West Country Sauce is just marketing twaddle, I have never heard of it before either.
Neither have I, and I agree that it's marketing twaddle as the West Country isn't a legally defined area.

Just touching base.

As far as I know/understand/believe, I have uploaded the sketch.

I don't understand why I got an e-mail reply saying someone had responded but there are no replies I can see.

There is/was a problem with this site about replies.
Sorry, that was me. I didn't see the attachment until after I'd posted my comment. I then deleted the post.

About 3/4ths in after he's finished showing off the pictures, check out the cb radio and the damage caused by a strike, that's insane!
About 15 years ago there was a lightening strike about 100ft from my house. It damaged a neighbours house quite severely (it demolished his chimney and set fire to some of the interior) and damaged another neighbour's TV, presumably through the aerial. But what was more surprising was that it blew up my telephone and (dial-up) modem. My telephone service cable runs underground until it enters my house!
90  Using Arduino / General Electronics / Re: Is it a standard to call outputs "Y" on ICs? on: August 11, 2014, 08:08:49 pm
It varies. Sometimes Y can be either an input or an output and Z is used to denote the opposite
(74HC4067 multiplexer/demultiplexer). Usually address pins are A (address), but sometimes S (select?). There seems to be no rhyme or reason to it. Different manufacturers use different conventions.
