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.

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.

Check that the code and screen work.

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.

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.

Work is complete - get a fortune!
