Intro:  Simple POV homemade arduino shield

Has Gunnery Sergeant Hartman (Full Metal Jacket) says during the riffle pray “There are many like it, but this one is mine”

Step 1: Material

Indeed there is many project like available on internet.

This one use a tilt switch as trigger

1 x Arduino board (http://shop.snootlab.com/lang-en/arduino/68-arduino-duemilanove.html )7 x 500 ohms resitors ¼ W7 x basic red leds1 x 10 k ohms resitors ¼ W1 x tilt switch (I use this one http://shop.snootlab.com/lang-en/parts/96-tilt-sensor.html )A piece of prototyping board plated holesMale header (0,1") 1 row, 40 pins (need only 28 for complet arduino connexion , and realy need 10 for this project) http://fr.mouser.com/ProductDetail/FCI/68004-236/?qs=sGAEpiMZZMtsLRyDR9nM10aphOtlQBeldG%252bobNTQj6E%3d

Tools

A PC to program the arduinoAn soldering ironSome tin

A cutter

Step 2: Prepare the boardYou have to cut the board to get a piece of about 21 x 18 holes (the hole spacing is 2,54 mm)For this kind of board, just score with a sharp knife, place a metal ruler or similar on the top and snap it.

Then you have to solder the Male header.First cut the male header in2 pieces of 8 pins2 pieces of 6 pins

Then, solder the Male header. Take care of the two 8 pins. They must be tilted to fit the arduino connectors. First, make a try with a single soldering point.

Step 3: Solder the electronics partsSolder the 500 ohms resistors. They must be connected to the male header of the arduino pin 6 to 12

Solder the leds. The “upper” leds must be on the pin 6

Solder the tilt switch and the 10 kohms resistor.

With my tilt switch, I’m using only two pins (see picture)

Add some jumper wire… and finally it should looks like the last picture

Step 4: The codeYou can tune these parameters

If you want faster display reduce those parameters#define delinterchar 700 //delay between 2 char#define delinterpoint 340 //delay between 2 points of a char

If you use deferent pin for your leds or for your sensor#define led1 6#define led2 7#define led3 8#define led4 9#define led5 10#define led6 11

#define led7 12#define sensorPin 2

Currently this code display two message : “SNOOTLAB” and “RULEZ”

The two messages are define inchar texte[] = "SNOOTLAB"; // data to write on startupchar texte2[] = "RULEZ"; // data to write after "repet" writing of the first message

The message changes after 10 displays. You can change this value here#define repet 10 //number of repetition before changing message

Step 5: Enjoy

I think there is many way to improve this, by using interruption for example. For this purpose, I have connected the sensor on the pin 2 of the arduino of the externalinterruption.If you made a think like this, please post this upgrade on instructable.
