/*SlotMachine.ino Version:1.0 Date:2018/07/01 - 2018/08/29 Device:ATMega328P-PU @ 16mHz Language:C Purpose =======A slot machine for entertainment and educational purposes only, with the following features:- AtMega328P microcontroller running at 16mHz - Custom I2C seven segment display for displaying credit balance, also built with an ATMega328P running at 16mHz. That program is supplied in a seperate file. - Three 8x8 LED matricies for displaying symbols driven by MAX7219. - I2C LCD display 20x4, to show menus - various buzzers, buttons and an RGB LED. - the ability to update various settings via the LCD menu to influence the machine's behavior. - the ability to change the amount of the wager. Known Defects =============- Sometimes one or two of the reels won't spin, not really a defect. - crash as soon as payed out exceeds 1,000,000. TODO ====- add brown out detection - add watch dog protection (wdt_enable(value), wdt_reset(), WDTO_1S, WDTO_250MS) Warnings ========- Beware of turning on too much debugging, it's easy to use all of the data memory, and in general this makes the microcontroller unstable. - Gambling is a tax on people who are bad at math. This is for entertainment only. It was the intent of the author to program this game to return ~%hold of every wager to the house, similar to many slot machines. - Why not control the LED that displays the credits with the LedControl library? I tried that and couldn't get more than one LedControl object to work at a time. So I had to create an I2C slave instead and use another AVR. Suggestions ===========- Best viewed in an editor w/ 160 columns, most comments are at column 80 - Please submit defects you find so I can improve the quality of the program and learn more about embedded programming.
