Decision Maker

Ever had a hard decision, but didn’t know how to go about deciding? Well, fear not! In this project, you’ll be building a program that will give you a yes or no answer to any question that you ask it.

The Amazing Annoyatron

Build this invention, and many more, with The Amazing Annoyatron!

What you’ll need

Brain Board

USB Cable

Step 1

Code some chaos!

Don’t forget to select your port, like ususal

Copy and paste the sample code

void setup() {
  Serial.begin(9600);
  Serial.println("                   oooo                                                              ");
  Serial.println("                   `888                                                              ");
  Serial.println(" .oooo.    .oooo.o  888  oooo        .oooo.   oooo oooo    ooo  .oooo.   oooo    ooo ");
  Serial.println("`P  )88b  d88(  \"8  888 .8P'        `P  )88b   `88. `88.  .8'  `P  )88b   `88.  .8'  ");
  Serial.println(" .oP\"888  `\"Y88b.   888888.          .oP\"888    `88..]88..8'    .oP\"888    `88..8'   ");
  Serial.println("d8(  888  o.  )88b  888 `88b.       d8(  888     `888'`888'    d8(  888     `888'    ");
  Serial.println("`Y888""8o 8""888P' o888o o888o      `Y888""8o     `8'  `8'     `Y888""8o     .8'     ");
  Serial.println("                                                                         .o..P'      ");
  Serial.println("                                                                         `Y8P'       ");
  Serial.println("Ask me a question and I will give you a yes/no answer\n");   }     void loop() {       randomSeed(analogRead(0));
if(Serial.available() > 0) {
    Serial.print(Serial.readString());
    Serial.println();
    delay(1000);
    if(random(0, 2) == 0) Serial.println("I say yes."); // The 'YES' message
    else Serial.println("I say no."); // The 'NO' message
    Serial.println();
    delay(1000);
    Serial.println("Now ask me something else\n");
  }
}

Upload the code and test it out

Step 2

Ask away!

Open the ‘Serial Monitor’

Click on the button shown in the image to open the Serial Monitor. A new window will pop up.

Send your message

Type in a message and click ‘Send’. The Decision Maker will respond!

Step 3

Modify the Madness!

Change the decision messages

Giving a simple yes or no answer to all of your questions is a bit boring, don’t you think? At the moment, when a question is being answered, you get a pretty plain response. If the answer is ‘yes’, then it just says: “I say yes.”, and nothing more.

if(random(0, 2) == 0) Serial.println("I say yes."); // The 'YES' message

To edit this response, all you need to do is change the text inside the quotation marks. For example, if I wanted to respond with, “The stars tell me that the answer to your question is yes.”, I would need to use the following code:

if(random(0, 2) == 0) Serial.println("The stars tell me that the answer to your question is yes."); // The 'YES' message

But that’s only the response when the answer to a question is ‘yes’. We can also edit the response to questions with a ‘no’ answer. The code for this can be found on line 18.

else Serial.println("I say no."); // The 'NO' message

Like with our the previous response, all we have to do to change this one is to change the text inside the quotation marks.
