Here's a summary of STEM Winter Activity: A Picobricks Mainboard with temperature and humidity sensors measures the ambient temperature for you, but keeps it secret from the players. Then players take it in turns to enter their temperature predictions. The closest guess wins the game.
Hello, future meteorologists! Let me introduce you to a great (literally!) project that is not only fun but also educational: Thermometer Game powered by PicoBricks. This game is the perfect mix of technology, learning and of course friendly competition. Perfect for cold winter days, this game is a STEM Winter activity that really warms up your brain cells!
Why This Game?
- Educational: It’s a hands on way to learn about sensors and how they interact with the environment.
- Seasonal Fun: Especially great for winter, this game adds a STEM twist to those long, cold days.
- Unit Conversion Made Easy: Players get to understand the difference between Celsius and Fahrenheit in a practical, engaging way.

Step 2: Choosing Celsius or Fahrenheit?
Turn on the PicoBricks and you'll see the OLED screen light up with two options: Celsius and Fahrenheit. Now, this part is interactive and educational! Depending on which temperature unit you're more familiar with (or just curious about), use the potentiometer to toggle between the two options. Made your choice? Great! Just hit the button to lock it in.
Step 3: Time to Guess!
Now, let's get to the heart of the game. Player One, it's your turn to guess what the ambient temperature is. Twist the potentiometer and watch the OLED screen as you make your guess. Lock it in and pass it over to Player Two, who then makes their guess in the same way.
Step 4: And the Winner Is...
Once both guesses are in, it's the moment of truth. The PicoBricks compares your guesses to the actual temperature it secretly measured earlier. The closest guess wins, and the screen displays a celebratory message for the winner!
