Build an Arduino LED Dice with MPU6050 & MAX7219 | DIY Motion-Sensing Dice

When it comes to learning and experimenting with electronics, nothing beats the excitement of building your own DIY projects. In this blog, we’ll guide you through creating an Arduino-based LED Dice that uses an MPU6050 accelerometer and a MAX7219 LED matrix to simulate a dice roll when shaken. This project is perfect for beginners and advanced makers looking to explore motion sensing and LED displays!

What is a Motion-Sensing LED Dice?

A traditional dice requires a roll, but in this project, we replace physical rolling with motion sensing! The MPU6050 accelerometer detects movement, and the Arduino Nano processes the data to generate a random number. This number is then displayed on the MAX7219 LED matrix, mimicking a real dice roll.

This project introduces motion detection, random number generation, and LED matrix control, making it an excellent hands-on learning experience for electronics and coding enthusiasts.

Components You’ll Need

To get started, gather the following components:

• Arduino Nano

• MPU6050 Accelerometer

• MAX7219 LED Matrix

• Breadboard

• Jumper Wires

• USB Cable for Arduino

All these components are readily available at KitKraft.in. Order now and start building your project today!

How Does It Work?

• MPU6050 Accelerometer: Detects movement when the dice is shaken and sends data to the Arduino.

• Arduino Nano: Processes the accelerometer data and generates a random number between 1 and 6.

• MAX7219 LED Matrix: Displays the generated number, simulating a real dice roll.

This combination creates an interactive electronic dice that reacts to motion, making it a great alternative to physical dice in board games, experiments, and fun DIY projects!

Circuit Diagram and Wiring

Here’s how you can wire up your components:

MPU6050 Accelerometer:

• VCC → Connect to 3.3V on the Arduino

• GND → Connect to GND on the Arduino

• SCL → Connect to A5 (I2C Clock)

• SDA → Connect to A4 (I2C Data)

MAX7219 LED Matrix:

• VCC → Connect to 5V on the Arduino

• GND → Connect to GND on the Arduino

• DIN → Connect to D5

• CS → Connect to D6

• CLK → Connect to D7

Ensure all connections are secure and double-check your wiring before powering up the circuit.
