Arduino Fortune Teller

Intro: 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.

STEP 2: Step 2

Check that the code and screen work.

STEP 3: Step 3

Using an old cigar box I created a shell for this project. I had to cut 4 holes for the LEDS, 1 hole for the LCD, 1 hole for the on/off switch and 1 for the button.

STEP 4: Step 4

Now for the tricky part, stuff all the wires into the box!
Here we hookup the battery by itself to the on/off switch, stuff everything inside and hookup all the LEDs.

STEP 5: Step 5

Work is complete - get a fortune!

what do tv2 and tv mean and is there a video on it oporating?
Thank you. I already have the push button switch hooked up in that manner. The switch I was asking about is the standard 4 pin one you have on the white bread board at the top (in your photo). I am wondering what that one is for and what pin you have that one hooked to. I see the one laying off to the side and assumed that is the one you hooked up to pin6. Hmmm... well I suppose I will just keep trying to figure it out. Thanks
Thank you for your help. I am still having a problem with my switch. I have it hooked up to pin6 and either I have hooked it up improperly or something isn't correct in my code. I have 3 LED's hooked up on a separate breadboard on G, H, I 20-21 connected to pin1 and they are lit but not blinking??? The LCD will give the first fortune automatically and then it reads "push button for fortune" "button needs pushing""push button please" when I push the button I get nothing and then it automatically loops to Fortune Teller Madame Zahara (what we named Robot) thinking.... and it all continues to loop. I see in your photos that you have a separate push button on the main bread board, is this something need to add and if so could you explain connection and what pin#? Again thanks for any help you are able to give to this old learning student.
I added your code that you gave me like this:

Yes, I have a separate button hooked up to pin 6 like this. On wire from the button goes to +5v. The other wire goes to a 1k resistor. the other side of the resistor goes to ground. Another wire then goes from pin 6 to where the resistor and the wire from the button meet.

pin 6
This is an awesome project. I am a student at UC Denver and I am doing this as a group project that will be exhibited at CU Boulder next week. My group is new to working with Arduino and we are trying to make the switch and LEDs work. We have a push button switch and do not know quit how to put it in the code so that when power is on and some one walks up to the podium (where our box will be placed) the LCD reads "Push Button for Fortune", Can you help? Currently the LCD continuously loops through ..."push button...Madam...thinking...fortune...lucky #..." Our other issue is wiring the LEDs for the thinking animation. I have the extra breadboard as well to connect the LEDs, could you explain the connection and any code changes (if necessary) to make these work in the thinking animation? Would love to send you pictures of our finished instillation at the Art Center on CU Boulders campus. Truly appreciate any help you can lend. Thank you!
It's been a long time since i looked at this code. I believe It gives one fortune automatically on start up then waits for a button press. To avoid that and wait for a pushbutton push try something like this: (Note The pushbutton is defined as pin 6.):
void loop() {
int val = digitalRead(inPin);
if (val == HIGH) // button has been pressed
{
// 1. go to led animation for "thinking"
// 2. go get fortune and print to screen
}
Also, here are two good resources to get you going. Good luck making it.

this looks like a cool project but when i tried to program the arduino i got 'LCD4Bit' does not name a type so can you help me
Hi,

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.

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 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
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.
there is no tutorial ..?
thanks, great instructable...you inspired me to make a similar arduino/lcd project with a temp sensor-
Did you use an LM35 temp sensor? I had good success with that one. What was your project?
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-
Looks fun and easy. You can also find other ways to program it!
