FINALIZED CONCEPT
I want to make a Mastermind game, which is a two-player board game where one person is the code maker, and they make a code using colored pegs. The other person is the code breaker, and they have to figure out the code in a limited number of moves. The less moves you take to figure out the code, the higher you score.
Originally, I was going to have wooden floats that would complete a circuit through conductive water. However, thinking that would make a mess and potentially be hazardous due to being close to electronics, I switched to using LDRs and LEDs to detect different colors.
The structure will be made using wood of the following dimensions:
I want it to be an enclosed box, so that the readings on the LDR are stable. My idea is that I can use LEDs of different colors, and different brightnesses to “detect” color, and then use that as input for the Mastermind game built in P5Js.
Arduino to P5Js Communication
The pegs will be the interface of communication, and placing a colored peg into one of the holes should communicate what color the peg is at the respective position. The sensor values that are measured are LDR readings, but I do not want to transmit raw sensor values. Instead, I will do the checks to figure out what color the peg is and in what position within Arduino. Then, I want to transmit the respective color positions to Arduino in the form of a code. There are 4 positions, and 5 colors. So, there are 6 options for each position, including having no peg. Therefore, I will generate a 4-digit code with digits 0-5, and that is what will be sent to P5Js.
Also, I want to add a button that is used to confirm the code selection. To convey that information, I can include a fifth digit in the code, with a 0 or a 1 to represent whether or not the button has been pressed. Any extra checks, like prevent the button from clicking more than once in a certain timeframe, will be processed within P5Js, so that communication is simplified.
P5Js to Arduino
Since my project is centered around an interesting control interface, there is nothing that I want to send from P5Js to Arduino, as the Arduino side is a game controller. Unless there needs to be some sort of syncing that needs to be done, which I don’t expect, there will be no communication back to Arduino from P5Js.
