Coin Toss Random Generator Kit with Arduino Uno: Learn Random() with a Fun Flip Animation

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Ever needed a digital coin to decide between two options? This kit lets you build a portable electronic coin tosser that shows Heads or Tails on a bright LCD screen with a flip animation each time you press the button. It’s the perfect way to explore how Arduino generates random numbers while creating something you can use daily.

What You'll Build

You’ll assemble the Arduino Uno, 16x2 LCD with I2C backpack, and a tactile button on the breadboard, then upload code that uses the random() function to pick an outcome. Every button press triggers a brief flip animation on the display before settling on Heads or Tails. The device runs on a 9V battery, making it portable for quick decisions or classroom demonstrations.

What You'll Learn

• Write Arduino code to control an I2C LCD – display text and custom animations
• Use the random() function to generate unpredictable outcomes on button press
• Wire a circuit with pull-up resistors to debounce a tactile switch
• Upload and debug code using the Arduino IDE and serial monitor
