If you’re unfamiliar with Liar’s Dice, watch Pirates of the Caribbean: Dead Man’s Chest — that’ll cover most of the rules. Alternatively, you can read the rules here: Liar's Dice Rules. Essentially, it’s a bluffing game where each player has a set of dice hidden under a cup, and players take turns bidding on what they believe is under everyone’s cups collectively. Remembering the total number of dice on the table and tracking each player’s dice is a great advantage. This project uses a matrix keypad and an LCD display to help make smarter calls during gameplay. The device prompts the user to input the total number of dice on the table (or your best guess), the quantity being called (for example, if someone says “seven 6s,” you input 7), the number of dice under your own cup, and the number of dice you have that match the face being called. Using this information, it calculates and displays two percentages: the probability that the bid is true (meaning there are at least that many matching dice on the table), and the probability that the total is exactly that amount. All input is handled through the keypad, and results are shown directly on the LCD. The LCD used in this build does not have I2C, so wiring may be simpler in some cases, depending on your setup. There are endless possibilities with matrix keypads and LCDs, from calculators to locking mechanisms and beyond. Have fun, and good luck bluffing! </body></html>
