Hello to all of you Arduino users,

Let me start introducing myself. My name is Erwin (a.k.a. ambuman) and I'm from Holland.

Recently I celebrated my birthday and guess what...
They've bought daddy an Arduino (with a breadboard and wire kit)!!!
Well..
You know how that goes.

Daddy searches the WWW...
Daddy orders his goodies...
After a propper inspection daddy passes the "secret box" that he got from the mail man to mommy...
Mommy wraps it up...
You figure out the rest, including the oohs and aahs...
 ;D


After playing around a bit with simple LED blinking speed and some Knight Rider fun I made up MyFirstArduinoProject  Huh

Here it is:


Let me know what you think of it.

Regards,

Erwin.

Very nice. I love flashing lights. as long as they are not on the cop car behind me.

[Reply #2 on:]

Cool!

Is the center LED supposed to light during that sequence?

[Reply #3 on:]

Thanks for your responses!

@ CodingBadly
Nope... I used the centre light in the Knight Rider program to test the stuff. In this program I left it out on purpose. It splits the two sides nicely.

Gr. Erwin.

Very nice! I was just thinking today of how simple the light bar in my car would be to make on an arduino and you've clearly shown how!

Looks like you've started on a new and long lasting hobby

I thought of interfacing to the electronincs in the car from work.
Probably that will make my boss go nuts... :o  >
The lightbar on my car sucks bigtime...

And the code?

[Reply #7 on:]

Oh well.. That wasn't so special.
Just an amazingly simple switch on and switching off with a few LED's.
 
Here it is.

Erwin.

Code:

// Emergency

  int LED1 = 1;     // the number of LED pin 1
  int LED2 = 2;     // the number of LED pin 2
  int LED3 = 3;     // the number of LED pin 3
  int LED4 = 4;     // the number of LED pin 4
  int LED5 = 5;     // the number of LED pin 5
  int LED6 = 6;     // the number of LED pin 6
  int LED7 = 7;     // the number of LED pin 7
  

//Timers and counters
  int timing = 30;
  byte count1 = 1;
  byte count2 = 1;
  byte count3 = 1;
  byte count4 = 1;
  
  

void setup ()

Next step is to port the project to a 3 pin usage

[Reply #9 on:]

Hmmm.... :o
I think I have to sleep on that for a few nights... :-/
 ;D

[Reply #10 on:]

I did a similar project.  Everyone loves police lights!  Using super-bright blue and red LEDs really helps get the right effect.  See http://nootropicdesign.com/projectlab/2010/01/08/arduino-police-lights/

There's a video, and the code is posted.

That's a nice one!
Bit more fancy coding than mine :o
I'm just a C/C++ newbie, but hey...
I'm learning in progress  
Thanks for posting!
