I dunno about that, why would anyone come from another planet and live here lol
I dunno, unless their planet is even worse than we've done to the earth?

That would make these aliens hypocrites then! (Ie not sharing because of wars)

Ps if you are an alien ... get your greencard lol

Jasmine, Moderator:
Your're right!!  With a resistor between cap and switch works fine!!

Thanks a lot!!

Do you think i've broken my Arduino trying without resistor?

Thanks a lot again!!!!



Nope, all that happens is the voltage level from usb drops causing the board to reset (along with the usb to serial ic) ..

Is the polyfuse causing it? I doubt it get's hot enough fast enough .

Test the battery's voltage level, could be low?

Depends on your code...

You could have 4 timer classes all fire off  and behave independenly of each other or you could be calling the same class 4 times and end up with memory issues...

But generally you pass the arguments, and then it goes off to where the procedure, function is in memory and begins executing the routine ... (not going into pointers, memory addresses,  stack and heaps, jumps etc)

696  Community / Bar Sport / the Ice Age starts now! on: January 07, 2014, 01:56:47 am
For the last 4 years I've been watching weather patterns and I am convinced we peaked a few years ago and now wers heading for an extensive cold period...

Finally scientists agree!

What I don't agree on is that we're heading for a mini ice age but a total one, I think the reason for the weird weather is man made, we release gasses to keep the planet warmer and earth equalizes through storms and rain and weird weather patterns.

Even if it's a mini ice age, not a full one expect things like the rivers and lakes to start freezing up solid in the next 5 - 10 years.
697  Using Arduino / LEDs and Multiplexing / Re: 56 leds - 7 shift registers - how to power them? on: January 06, 2014, 11:14:46 pm
You could use an IC like this


http://www.ti.com/lit/ds/symlink/uln2803a.pdf

All your outputs are fed into the 2803 and then it sinks (I think been a while) your LEDs... you'll need a resistor on each led(led/string)

I don't understand why ujts were phased out they're useful...

699  Using Arduino / General Electronics / Re: Working with 5v component(s) in 3.3v Arduino? on: January 06, 2014, 07:11:02 pm
You're refering to a pull up .. (or pulldown but not with this sensor)


Think of a pullup as a rope, the rope pulls keeping the object securely to the wall, how strong the rope is the resistance value, lower the resistance stronger the rope. Without the rope the object will move around the room giving you false results.

In Arduino terms, this is called floating, to keep it from floating a resistor keeps the value high at 5v or low at 0v  so a 1k or 10k would work just fine if the sensor is able to overcome the current from the resistor.

First question.

Why are you using pin 1 (don't)

One of my first experiments with 120v was when I was 8 years old, during construction of a room in my parent's basement.  A life wall switch had no plate on it, and when my finger slipped and touched the hot screw and the grounded box I got a shock.  I tried touching the other screw (neutral) and got no shock.  I wondered if all the boxes were connected in a circuit, so I carefully touched my finger to the hot screw without touching the switch box, and then touched my toe to the electrical box of a nearby outlet.  I got a good jolt but was unharmed and had a rather memorable start to learning electronics.

William Shockley would have paid you...

Yeah, except in cpp/java you can have private/public sections where only that class an access the properties. And theclass.something (); wont exist unless called within the class unless you specify it to be public

I love Arduino because I can get away coding like I did back in 1994 learning C.

Think of an orchestra.

Each musician is trained to use his or her instrument, each person knows a set of rules when to play when to stop, and when combined with all the other instruments they all behave as 1, they're not all playing different music.

The conductor is you.

PianoPlayer.play ();
Delay (1000);
ViolenPlayer2.play ();

So you write a class foundation which has the basic properties of all, they all have names.

Since each class is encapsulated allof it's variables, functions are all together so you don't need to worry about overwriting variables because they're all tucked away inside the class.


But as you can see

Turns out I'm a manipultive bastard smiley but I rank low for everything except for the machivalian test (74/100  smiley-eek-blue)
