Re: Need a controller that is not expensive
OK, I said I would get back and here we go.
I plan on having a "haunted graveyard" this year.
What I want to do is this:
1. My grave yard is out with devices etc. with ambient sounds
2. as the kids walk down my sidewalk I have a beam sensor for them to trip
3. a loud scream happens and a zombie pops up for a few seconds then resets
4. GhoSteps walk from the zombie, with moans, to a gate and pause
5. the gate opens with a long creeeeek
6. GhoSteps walk through and the gate closes
Here is how I did it (just cut n paste to Arduino): {the ASCII art will show in the Arduino program}

More pictures are comming soon.

2011 Project - By Sparkey
Control of a Halloween Graveyard Display through an Arduino with an Eight Relay card.
------------------------------------------------
------------------------------------------------
Parts List:
01. Arduino Duemilanove
02. Arduino Sensor Shield v4.0 - yourduino.com - p/n AS-010200
03. 8-Relay Board, optio-isolated - yourduino.com - p/n EA040402
04. Wires for pins on shield & relay card - yourduino.com - p/n CW-044020
05. Beam Sensor - Velleman Kit MK120 - http://store.qkits.com/moreinfo.cfm/MK120
06. Magnecraft W117SIP-6; 5 VDC SPST N.O. DIP REED RELAY - http://www.allelectronics.com - p/n CAT# RLY-541
07. LM7805CT; Standard Voltage Regulator 5 Volt - http://www.jameco.com - Part no. 786138
Note: the beam sensor activates a 9VDC buzzer, you will not use this. The reed relay and voltage regulator are inexpensive so
I used the voltage regulator to bring the 9V down to 5V, because that is what the reed relay is rated for, and used the relay
to act as a DRY CONTACT, aka switch thinking I could copy the DEBOUNCE sketch, for a binary input which will activate the Arduino.
08. 20k Ohm resistor
09. Ghostly Footprints - http://www.halloweenforum.com/hallow...ootprints.html
10. 2 Pneumatic solenoid valves - http://www.frightprops.com/pneumatic...0927-0001.html
11. 2 Pneumatic actuators - http://www.frightprops.com
12. 300 second USB recording module - http://www.electronics123.com/ - Product # USB5M
13. Air compressor - mine is an old 26 gallon unit
------------------------------------------------
Recommended software:
01. Audacity - Used to edit your sounds. - http://audacity.sourceforge.net/
Audacity® is free, open source software for recording and editing sounds.
02. CDEX - Used to change MP3 to WAV, and back, format for your sounds. - http://cdexos.sourceforge.net/
CDex - Open Source Digital Audio CD Extractor

Notes on my setup............................................. .....
AUDIO FILES-1,2,3,4
300 second USB sound card has 4 push buttons to activate 4 individual sounds, so a CLOSED relay would = on
I soldered in lenghts of wire, keeping the buttons for testing, to go to the various relays for activation.
This card also has multiple programable functions like auto-repeat so I setup #1 to replay on its own.
1= AMBIENT NIGHT SOUNDS = KG-background-02.wav, I made with Audacity
2= Crypt_laugh.wav, from the www
3= CorpseMoan.wav, from the www
4= GATE OPENING/CLOSING = KG-Gate07.wav, I made with Audacity
---------------
AIR VLV-1,2
I am using two 24VAC solonoid valves which will activate two pneumatic props, so a CLOSED relay would
allow a POWER ON condition, solonoid activation, and air to flow which runs the two pneumatic actuators.
Prop-1 = zombie popper
Prop-2 = haunted gate
---------------
Prop-3 = GhoSteps, 9VDC series of lights, needs an on, so a CLOSED relay would = on
The Ghost Steps card runs 16 steps and has some timer/programming features, like delay, which I have used so
one must match the event timing to what you choose to program the card to do.
------------------------------------------------
NOTES ON SETTING UP THE HARDWARE.......................................... ...
Place the Arduino Sensor Shield on the Arduino Duemilanove.
Run wires from the RELAY CARD to the SHIELD CARD as follows, WIRE COLORS ARE WHAT I USED TO KEEP THINGS STRAIGHT.
RELAY WIRE SHIELD DIGITAL I/O
GND --> BLACK --> 0G
IN1 --> BROWN --> 1S
IN2 --> YELLOW --> 2S
IN3 --> ORANGE --> 3S
IN4 --> RED --> 4S
IN5 --> PURPLE --> 5S
IN6 --> GREY --> 6S
IN7 --> BLUE --> 7S
IN8 --> GREEN --> 8S
VCC --> WHITE --> 0S
SETTING UP THE REED RELAY...................................Diode protected, voltage/polarity matters..........
If you are asking why use relay when I can get power from LM7805, ANSWER = CIRCUIT ISOLATION.
RELAY HAS 4 PINS: NUMBERS (Left to Right looking at name/data) = 1, 3, 5, 7 .... 3 = +volts, 5 = GND, 1 & 7 = NO Switch
LM7805CT HAS 3 LEGS (Left to Rightfs) = 1, 2, 3 .... 1 = INPUT VOLTAGE, 2 = GND, 3 = OUTPUT VOLTAGE
IR BEAM SENSOR BUZZER VOLTAGE = 9VDC
route the IR-9V -to-> LM7805CT LEG-1 and the IR-GND -to-> LM7805CT LEG-2
route the LM7805CT LEG-2 -to-> RELAY PIN-5 and LM7805CT LEG-3 -to-> RELAY PIN-3
YES, LEG-2, The GND is shared between INPUT and OUTPUT

Magnecraft REED RELAY pins 1 & 7 are Normally Open. Solder wires on these two pins, with a 20k resistor on pin 7, and run them as
you would for the BUTTON sketch.
RELAY PIN-1: IN gets controlled power from SHIELD 5V PIN.
RELAY PIN-3: IN gets relay operational power circuit from LM7805CT LEG-3
RELAY PIN-5: OUT gets GROUND for relay operational power circuit from LM7805CT LEG-2
RELAY PIN-7: OUT sends 5VDC to 10K RESISTOR and SHIELD PIN-8 (ON INPUT SIDE OF RESISTOR) then to SHIELD GND (on output side of resistor)

NOTE TO ME,
Want to add a constantly dimming set of eyes while the above program runs, need to learn PWM on pin 10?
try this later when the rest of the stuff is working
int fade_eye = 0;
int ledpin = 5;
void setup ()
{
}
void loop ()
{
for(fade_eye = 0; value <= 255; fade_eye+=5)

analogWrite(ledpin, fade_eye);
