Accelerometer Brush

1- We will explain the workshop session for the participant day by day.

• Participant will start in this day to create their drawing using the microcontroller after they code it as a paint brush.
• In the second day, they will convert their 2D drawing into a 3D object.
• Finally, they will add their 3D object to a virtual reality environment.

2- Then we will ice break with the participant to let them engage in the session.

3- Then we will discuss and explain the meaning of science.

4- Then we will speak a bit about the Art and its unlimited definitions.

5- Then we will show the linkage between the art and the science.

6- Then we will ask the participant how they could define art and science from their perspective.

1- We will show the participant the prototype we want to build and the needed material to have the prototype done.

2- Then we will talk about software as instructions written in a sketch and the computer will execute these instructions one by one.

3- Then we will show the participant the types of coding and the one we will be using today, which is block coding.

4- Then we will present a video that explain the meaning of coding and its types in addition to a number of coding languages.

5- Then we will ask the participant about the uses of the coding process.

6- After describing the need for software and how to use it, we will explain the need for a microcontroller and how it works.

7- Then we will talk a bit about what is meant by input devices and how they work with microcontroller.

8- After mentioning the input device and explaining them as devices, to grab data from the surrounding to be processed using the Microcontroller in order to take an action According to the processing result.

9- We will explain the accelerometer sensor and how it’s used and works.

10- Then we will ask the participant about what they think accelerometer is used for.

11- Then we will show some of the art pieces that been drawn using the data of the accelerometer.

1- We have to ask the participant to open scratch software for the offline version or the website if they are using the online version.

2- Then we will talk about The extensions needed to have all the instructions to code on scratch.

3- Then we will start our code by explaining the need for events.

4- The code will start with creating a variable for the step of the pen and also another variable to change the colour of the pen.

• We can also create a variable for the size of the pen, but it depends on the application we want to have it at the end.

5- Then we will add the pen size instruction from the pen extension.

• It’s not necessary to start drawing from the centre always, but it can be satisfying.
• As an initialization, we will erase every thing on the sheet to start a new drawing.

6- Then we will add the forever loop, and we will add the point instruction, so the pen will always follow the mouse pointer in addition we will add the move step for the pen, and we will add the variable we created for the value.

7- Then we can create the case function using the if condition for the colour of the pen.

• It’s important to add more than 3 colours to see a good result.
• At the end, we will add if condition to stop and reset the counter.

Note: It’s important to use dark colours so the trace tool being able to trace the lines, so we can extrude the lines.

8- Then we will code the keys to change the colour of the line and also for the reset.

9- Then we will jump to make-code Adafruit Platform to code the microcontroller.

• In this side of the code, we will code the microcontroller to control the mouse pointer and also some of the chosen keys from the keyboard.

10- Our coding process will start by adding the extension for both the mouse and the keyboard.

11- Then we will sense the change in the accelerometer of the microcontroller, and we will add a condition for (Y-Axis) and (X-Axis) to move the mouse pointer according to the tilt sensing.

12- Then we will add on-start loop as initialization animation, which is not mandatory to add.

13- Also we will code the replica of the keyboard keys like the A-push button and the shake function of the microcontroller.

14- By finishing this, we are done to test the microcontroller with what we have done in scratch.
