Arduino Fortune Teller

This project gives the user a fortune and lucky number like from a fortune cookie. This was made as a Christmas present.

Step 1 Step 1

Solder header pins onto LCD. Solder wires to female header pins and hookup to Arduino. Here we used the LCD 4 bit Library and hooked it up accordingly. This is slightly different the using the 8 bit library.

I want to take that a step further, with several buttons to get random entries from different fortune files. (fortune database)
I'm probably going to use a 40x4 display, and an SD card.

Cool. Let us know how it turns out fmoser.

Hii new to instructables and programming... I have compiled the code you provided for the fortune teller only i receive and error in the first instance!

**line of code highlighted**
LCD4Bit lcd = LCD4Bit(2);

**Error message**
LCD4Bit DOES NOT NAME A TYPE

Can you please explain why and how to fix this please :)

Thanks

Hi,
I have not used this in a while.
Try using the code below
You should include the Liquid Crystal library and maybe the Wire library.
If you are missing either of these , look at http://arduino.cc/en/Reference/Libraries .
Also make sure you wire up the pins correctly to (12, 11, 5, 4, 3, 2);

Hope this helps.

Hi Paulys,

This is a really neat project. Do you have a schematic for it, or a wiring diagram? I am trying to understand how to make an LCD interactive project and yours seems like a good place to learn. I don't have a grasp on how the momentary button interacts with the LCD menu.

Thanks for any advice,
Jeremy

[Paulys]

Sorry Jman, no diagram.  I did this over a year ago.  I would start with the LiquidCrystal tutorial if you haven't already.  http://www.arduino.cc/en/Tutorial/LiquidCrystal.
For the button, basically I' m suing a do while loop.  I animate the LEDS while b=0.  If b<>0, then I go grab a new fortune.

Good luck.

[Mario1]

there is no tutorial ..?

[sweenes]

thanks, great instructable...you inspired me to make a similar arduino/lcd project with a temp sensor-

[Paulys]

Did you use an LM35 temp sensor? I had good success with that one. What was your project?

[sweenes]

Yup I used an LM35..fried the first one when I connected it wrong so I was glad I bought two! The project was a cigar box with lcd with temp sensor poking out. Every 10 secs the arduino will refresh the reading and print to the lcd...thinking about adding more sensors, maybe humidity or something-

[chilll2009]

Looks fun and easy. You can also find other ways to program it!

[amando96]

thats nice! i think i'm gonna suck at programming :(

[chilll2009]

just copy and paste-duh '=' !!!!!

[amando96]

i wasnt refering to this just programming in general, and btw i can do almost anything in C by now...

[dnhoshor]

I'm just getting into the arduino stuff, and this looks like a fun, do-able project. I think I'd add a coin slot so that when a coin is inserted, it closed the circuit to start the fortune teller.

[tornadoboy]

Try finding a Nintendo arcade game coin mech on Ebay (Mario Bros, Player's Choice 10, etc), they're compact, don't require a full size coin door to mount to and turn up on there for next to nothing sometimes.

[diaz]

Great project! I'd like to see a parts list and sources for the parts.

[Paulys]

Thanks Diaz.
I used a 16 x 2 LCD from Sparkfun, 4 LEDs, an Arduino from Sparkfun, 2 2.2 resisitors to connect the backlight on the LCD, a pushbutton switch and a small slider type switch to turn it on and off. I also used male headers to solder to the LCD and corresponding female headers to connect the wires to the breadboard. You can also buy some of thes parts at Adafruit as well, although they don't sell the LCDs.

[Bongmaster]

u seem to have "link is invalid" throughout the code. the project looks nice tho :)

[Paulys]

Thanks, I fixed it. for some reason Instructables doesn't like square brackets. If you need the actual code, download the .PDE file in step 5 and convert it to a .TXT file.
