Catapult System

Project Purpose: To make a catapult project using Pinoo Control Card, button module and servo motor.

Duration:  2 lessons

Age group:  7 years and older

Pinoo Set:  Invention set, maker set and full set.

Achievements:

  • Learns to code Pinoo control board.

  • Learns to use the button module.

  • Learns to use servo motor.

  • Develops algorithmic skills.

  • Coding skills develop.

 

Materials to be used:  Mblock 3 program, pinoo control card, servo motor, button module.

 

 

 

Materials Required for Design:  Pieces of wood, acrylic paint, 11 colored popsicle sticks, stir stick, scissors, 3 pharmacy rubbers, plastic bottle caps, glue gun and silicone.  

 

Project Construction:

Let's start with making the platform on which we will place the catapult for our project. We paint wooden parts with acrylic paint.

  

  We siliconize the wooden parts as in the figure.

 

We're starting to make the catapult. We siliconize 4 ice cream sticks as in the figure.

  

  We silicone the other ice cream sticks as in the figure.

 

 

  We silicone the ice cream sticks as in the figure.

 

  We silicone an ice cream stick to the upper part.

 

We silicone the pet bottle cap on the ice cream stick.

 

  We silicone an ice cream stick at the bottom. We attach the ice cream stick with the lid to that stick with rubber.

 

 

 

We are increasing the number of tires. 2 tires will be installed.  

 

  We silicone the catapult onto the platform.

 

  We remove the tip of the servo motor and siliconize it as in the figure.

 

 

We also siliconize the button module.  

 

  We tilt the catapult and cut the stir bar according to the distance between the servo motor. We silicon the end of the servo motor to the rod as in the figure.  

 

  We attach the connecting cables of the sensors.

 

  We attach the other ends of the connection cables to the pinoo control card. (Button 1st Door Servo Motor 2nd Door)

  

We also plug in the USB connection cable. Now we can start coding.

 

Adding Pinoo extension:

 

From the Extensions tab, click "Manage Extensions".

 

  In the window that opens, we write “Pinoo” in the search engine and it is enough to say download to the result. Installed on our computer.  

 

 

 

Connecting the Pinoo control board to the computer:

 

In Mblock 3, we click on the "Connect" tab in the upper left. In the window that opens, we click on the "Serial Port" section and select the "COM6" option from the page that opens.

NOTE: As each computer has different port entries, the numbers next to COM may change.

 

 

Click on the Cards tab. From the window that opens, we select the "Arduino Nano" card option used by the Pinoo control card.

 

 

Click on the Extensions tab. In the window that opens, we select "Pinoo", the extension of the control card we use.

 

 

Click on the Connect tab. Click "Firmware Update" from the window that opens.

 

Coding:  

  First, we make the angle of the servo motor 90 degrees and attach the end of the servo motor.

  We tilt the catapult and bring the servo motor to 0 degrees.

 

 

It will look like this.

 

We print it on the screen to see the button status. (You will see 1 when pressed, 0 when not pressed.) 

We create the condition that the button state is 1.

We make the angle of the servo motor 90. In this way, he will throw a catapult. In 4 seconds we will lower the catapult and bring the servo motor back to the 0 angle.

We create the condition that the button state is 0. Then we adjust the angle of the servo motor.  

  In order to upload our codes to the pinoo control card, we start our event with the "Pinoo Program" command and delete the code we use to see the button value on the screen.

  

Right-click on the “Pinoo Program” command and in the window that opens, “Install to Arduino”  We select the option.

  

On the page that opens, we click on the "Upload to Arduino" button, which is selected in red.

 

  

Our codes are uploaded to our Pinoo control card.

 

  

 

After the “Installation Finished” message comes, click the “Close” button.

 

 

  Working Status of the Project:

  

We insert the 9V battery.

 

We press the button.

 

 

  Servo motor will stay and catapult will work.
