Final Project

Keep Talking and Nobody Explodes Party Game

Introduction

Keep Talking and Nobody Explodes is a party game created by Steelbox Studios. The core gameplay involves a “bomb defuser” interacting with a procedurally generated bomb while a “bomb expert” communicates specific instructions to the defuser on how to disarm the device from a manual. The bomb expert is not allowed to see the bomb, and the defuser cannot see the manual. The base game includes fourteen puzzles, or “modules”, and typically the defuser has three strikes to disarm the bomb. Each module is independent and can be solved in any order. Each bomb has a certain time limit, typically ranging from two minutes to eight minutes. Upon receiving a strike, the timer speeds up by a small amount, creating more pressure for the bomb defusal team. Once all the modules are completed successfully under the time constraint, the bomb is defused and the players win. If the bomb explodes, the players lose.

I own a version of this game on my desktop at my house and I have played it many times with my friends. I knew I wanted to create a game of some sort, and creating a physical version of Keep Talking seemed like a stellar idea to me. I chose this project specifically because I knew it would be less wiring and more programming. I found some example projects on github as well, but these all used an Arduino. I needed to use an MSP43X microcontroller to meet the project requirements. I decided to build my project from the ground up, and settled on the MSP430G2553 as my board of choice.

Methods

To begin, I had to choose which of the bomb modules I would program. The first one I chose was the password module. The module consists of a lit display containing a scrambled five letter word. Buttons can be pressed to cycle through the letters. This module is very similar to that of an alphabetic combination lock. The goal is to find one of the thirty-five keywords that defuse the module. To display the scrambled keyword with the microcontroller, I chose to use an SSD1306 OLED display. This display contains four pins: GND, VCC, SDA, and SCL. The MSP430G2553 has one USCI capable of I2C communication, so I had to connect the SDA and SCL leads to pins 1.7 and 1.6, respectively.

As for the buttons, I wired to a breadboard and connected to pins 1.0, 1.1, 1.2, 1.3, and 1.4. I was shopping for buttons on the internet, but a colleague of mine had purchased some in bulk and he let me use some of his. I did not end up purchasing any more on the internet.

The next module I programmed was called keypads. This module consists of a keypad containing four keys. I used the ADA1332for this project.The keys have different symbols on them. The defusal manual has six columns of symbols. The four symbols on the keypad can only be found in one of the six columns. Once a column is determined, the keys must be pressed in order from the top of the column to the bottom. If the keys are pressed out of order, a strike is given. This module contains very unique symbols and this makes communications quite challenging. I found a very cheap keypad on the internet, and wired the keys to pins 2.0. 2.1, 2.2, and 2.3. Each module was intended to have indicator LEDs that lit up when their respective modules were defused. I got the LEDs to work sporadically, but not consistently. They would light up at the wrong time.

There were a few more modules I wanted to attempt, but I ran out of time bug chasing. One module would have been an LED that flashed a word in Morse code. The word corresponded to a keycode. The defuser is required to enter the right keycode to defuse the module. More modules would have been a futile venture on the G2553, as there were barely enough pins for the two modules I had.

Results

See the Appendix for the source code and the circuit diagram of this project. The most difficult part of this project for me was resource management. I realized that the microcontroller I chose did not work for my application, and I spent a lot of time trying to change boards. I got the password module to work completely, but the MSP430G2553 only has 450 bytes of RAM. According to Code Composer Studio, I was using 427 bytes after the first module alone. When I tried to program in a timer and a strike system, I would run out of memory. The keypad module did not work for this reason as well. I attempted to switch boards to no avail. I changed all my code to adapt to the MSP430F5529, as it has four KB of RAM, which is more than enough for my program. I successfully converted my code so that it compiled for the F5529 without any errors, but when I tried to use I2C to communicate with the OLED, all I had to show was a blank screen. I tried deleting the old library I had pulled for the MSP430G2553 and importing a new one for the F5529, but I was still getting the same issue. Another downfall was that I began to run out of pins on the MSP430G2553. I was happy with the number of pins on the F5529, but I was stuck with the G2553.

Some various industry standards that were used include C, C++, and I2C. USB was also used to program the board from the user desktop. This project is not necessarily one that would be marketable except in its digital form. This was more for personal enjoyment. If it were to be marketed, it would have to follow FCC guidelines.

There are numerous impacts that my project would have on the world. First, it would have the social impact of creating great memories with your friends and family. It would bring people together while also building problem solving and communication skills. As far as the cultural impact, it would force the players to get out of their comfort zone, especially if trying to play for the first time with a stranger. It would not have much of an economic impact, but there is a chance that it could be marketed as a game, possibly in the toy section of some brand name stores such as Target or Walmart. Globally, this game can be translated into any language. It does a great job of playing into the nuances of the English language, especially the confusing aspects.

Conclusion

This project was a good way to build on our preexisting knowledge and get used to using libraries to make coding more complex and efficient. I learned how to use functions that other users have created. One thing I would do differently for this project would be to start with the correct microcontroller. If I had started with the MSP430F5529, I would have gotten much farther. In retrospect, I believe I could have gotten much farther if I had used an Arduino and some preexisting libraries from similar projects. I was worried that my complexity score would be too low. I am excited to use the knowledge I learned from this course in future courses and in my career.
