[Robotgroup] Fortune teller

[Jerry Rutherford]

Easy to implement. You could use an Atmel chip like the Mega-8 and a simple
LCD module. The whole circuit would consist of nothing more than...

LCD Module
Atemel Mega-8
Push Button
1K Resistor
10K resistor
10K variable Resistor - Contrast for LCD

The program can be written in the FREE version of BASCOM, the LCD command is
easy to use...

LCD "The Answer is yes."

The connections are not bad either...  BASCOM Manual:
http://avrhelp.mcselec.com/index.html

Look under Hardware --> Attaching an LCD.

It is 6 wires from the chip to the LCD, 2 wires to ground, one to 5v, and
one to the contrast resistor.
The chip needs 1 ground, 1 5v.
The switch gets connected to the chip with the two resistors

Done.

The program is not that hard... press the button, get a random number,
display the result.
