Pathfinder – Tiny Reaction Game!

Hello!! This is my Hack Club Stasis project its based on reaction time and a bit of fun

How It Works

• LEDs blink
• You press buttons
• Turn the knob
• Try to react FAST!!

Rules:

• Press button 1 -> led 1 lights up
• Press button 2 -> quickly after btn1 -> builds combo both will get on
• if you press button 2 quickly and multiple times then led2 turns on
• Too slow? nothing happens

Code

int btn1 = D0;
int btn2 = D1;
int led1 = D2;
int led2 = D3;

int potentio = D4;

long btn2cnt = 0;
long button1time = 0;
long button2time = 0;

void setup() {
  pinMode(btn1, INPUT_PULLUP);
  pinMode(btn2, INPUT_PULLUP);
  pinMode(potentio, INPUT);

  pinMode(led1, OUTPUT);
  pinMode(led2, OUTPUT);
}

void loop() {

  int pot_reading = analogRead(potentio);
  int brightness = map(pot_reading, 0, 1023, 0, 255);
