Arduino MPU6050 Interactive scrolling game on 32x8 Led Matrix

  This time I will show you how to make an interesting interactive game, on a 32 by 8 LED matrix, which is controlled by moving the device. During a certain movement of the device, the MPU6050 sensor sends a signal to the microcontroller, and based on that information, the microcontroller performs a given action on the screen. 

  In fact, the sensor represents a so-called air controller that we can find as part of remote controls for modern TVs. The project is featured on Benjamin Balogh's GiHub page (https://github.com/benibalogh/LEDMatrix-Games), where you can find the original code. The source code is made in Visual Studio with support for Arduino, known as Visual Micro.

  Unfortunately, after compiling and uploading the original code to the Arduino, the device did not process data from MPU6050, and only scrolled the text "Wall Scroller". I tried to contact the author several times, but without success. After certain time of studying the code, with one small modification, I managed to adapt it. Also, instead of Visual Micro, I compiled it into a standard Arduino IDE.

 To compile the code without errors, you should open the code from the given folder that contains all the required libraries. Let me emphasize that if you have previously installed any of these libraries in the Arduino IDE, you should delete them. I also added some simple tones to the code that don't interfere with gameplay and make the game much more interesting.

 The device is extremely simple to build and consists of only few components:

   - Arduino nano microcontroller

   - MPU6050 Gyroscope + Accelerometer sensor module

   - Buzzer

   - 32x8 Led matrix module with MAX7219 drivers

   - Battery, optionally like in my case one 3.7 Volts Lithium battery with charger, and boost module. Of cource you can use ordinary 9V battery, or external Power Supply.

   - and two switches

 If you want to make a PCB for this project, or for any other electronic project, PCBway is a great choice for you. PCBway is one of the most experienced PCB manufacturing company in China in field of PCB prototype and fabrication. They have a large online community where you can find a Open Source projects, and you can also share your project there. From my personal experience I can tell you that on this community you can find many useful projects with alredy designed PCBs, from where you can place an order directly.

  Finally, the device is installed in a suitable case made of PVC board and covered with colored wallpaper.
