Fatleys Pi Pico Reaction Time Game

i am makeing a led light reaction time game with a rasberry pi pico your results will be shown on a screen conected to the pico on a breadboard it will be played with 2 people to see who gets the fastest score the code will be run thrpugh thonny and micro python

Materials

rgb or led lights x2

pi pico rasberry pi x1

bread board x1

wires x15

screen to display the scores x1

Tools

Laptop x1

the file below is how i wired everything up and the pins i conected everything to were it needed to go

this can be different for everyone but for me the first thing i did was solder my arcade buttons so i can conect them to the pi pico there is a image above

after you have solderd the buttons its time for you to conect everything together if you dont wanna do it fron scratch use the file i uploaded earliar i also uploaded it on this step for ease of acces

after you have done all thoes steps you will need to open the app you are running the code through i am useing Thonny

once you open it up i have listed the code down below for you to coppy and paste into Thonny

#include <Wire.h>

#include <LiquidCrystal_I2C.h>

const int redButtonPin = 4; // Player 1

const int blueButtonPin = 5; // Player 2

const int redLEDPin = 10; // Player 1 win

const int greenLEDPin = 11; // GO signal

const int blueLEDPin = 12; // Player 2 win

LiquidCrystal_I2C lcd(0x27, 16, 2); // I2C LCD

unsigned long goTime = 0;

bool waitingForPress = false;

bool gameStarted = false;

void setup() {

pinMode(redButtonPin, INPUT_PULLUP);

pinMode(blueButtonPin, INPUT_PULLUP);

pinMode(redLEDPin, OUTPUT);

pinMode(greenLEDPin, OUTPUT);

pinMode(blueLEDPin, OUTPUT);

lcd.begin();

lcd.backlight();

randomSeed(analogRead(0)); // Random seed

lcd.print("Reaction Game");

delay(2000);

}

void loop() {

if (!gameStarted) {

lcd.clear();

lcd.print("Get Ready...");

delay(1000);

int waitTime = random(2000, 5000); // 2–5 seconds

delay(waitTime);

lcd.clear();

lcd.print("GO!");

digitalWrite(greenLEDPin, HIGH); // Signal to go

goTime = millis();

waitingForPress = true;

gameStarted = true;

}

if (waitingForPress) {

if (digitalRead(redButtonPin) == LOW) {

showWinner("Player 1", redLEDPin);

} else if (digitalRead(blueButtonPin) == LOW) {

showWinner("Player 2", blueLEDPin);

}

}

}

void showWinner(String player, int ledPin) {

waitingForPress = false;

gameStarted = false;

unsigned long reactionTime = millis() - goTime;

digitalWrite(greenLEDPin, LOW);

digitalWrite(ledPin, HIGH);

lcd.clear();

lcd.print(player + " Wins!");

lcd.setCursor(0, 1);

lcd.print("Time: ");

lcd.print(reactionTime);

lcd.print(" ms");

delay(3000);

digitalWrite(ledPin, LOW);

lcd.clear();
