Story

The project is based on a built-in accelerometer where we detect the force of the movement.

In this tutorial we will use dots as on the real dice but if you prefer numbers you should check out this tutorial:

Step 5: In Visuino Connect Components

1 / 5

Connect M5 Stack ATOM Matrix > Accelerometer pin [X] to "AccelerationToAngle1" pin [X]
Connect M5 Stack ATOM Matrix > Accelerometer pin [Y] to "AccelerationToAngle1" pin [Y]
Connect M5 Stack ATOM Matrix > Accelerometer pin [Z] to "AccelerationToAngle1" pin [Z]
Connect "AccelerationToAngle1" pin [Force] to Abs1" pin [In]
Connect "Abs1" pin [Out] to CompareValue1" pin [In]
Connect "CompareValue1" pin [Out] to "Timer1" pin [Start]
Connect "Timer1" pin [Out] to "ClockGenerator1" pin [Enabled]
Connect "ClockGenerator1" pin [Out] to "RandomIntegerGenerator1" pin [In]
Connect "RandomIntegerGenerator1" pin [Out] to "IntegerMultiSource1" pin [In]
Connect "IntegerMultiSource1" pin [0] to "M5 Stack ATOM Matrix" > "Fill Screen1" pin [Clock]
Connect "IntegerMultiSource1" pin [1] to "ClockDemmux1" pin [Select]
Connect "IntegerMultiSource1" pin [2] to "ClockDemmux1" pin [In]
Connect "ClockDemmux1" pin [0] to "M5 Stack ATOM Matrix" > "Draw Scene1" pin [Clock]
Connect "ClockDemmux1" pin [1] to "M5 Stack ATOM Matrix" > "Draw Scene2" pin [Clock]
Connect "ClockDemmux1" pin [2] to "M5 Stack ATOM Matrix" > "Draw Scene3" pin [Clock]
Connect "ClockDemmux1" pin [3] to "M5 Stack ATOM Matrix" > "Draw Scene4" pin [Clock]
Connect "ClockDemmux1" pin [4] to "M5 Stack ATOM Matrix" > "Draw Scene5" pin [Clock]
Connect "ClockDemmux1" pin [5] to "M5 Stack ATOM Matrix" > "Draw Scene6" pin [Clock]

Step 6: Generate, Compile, and Upload the Arduino Code

In Visuino, at the bottom click on the "Build" Tab, make sure the correct port is selected, then click on the "Compile/Build and Upload" button.

Step 7: Play

If you power the ATOM Matrix module and shake it the Display will start to show a random dice number from 1 to 6.
