FLAPPY PAPER BAT

Hi, makers, in this Instructables, we are going to make a flappy paper bat that flaps its own wings using a servo motor and an Arduino Uno. So, let’s see how to make it.

Components

1. Bat Paper Stencil
2. Black Craft Paper
3. Paper Cutter
4. Scissor
5. Glue
6. Tape
7. Black Thread
8. Arduino Uno with USB Cable
9. Micro Servo Motor with four arms horn x1
10. Male to Male jumper Wire x 3

Software

1. TInkercad
2. Arduino IDE

So, for making the wings flappy we'll need some actuator so that the wings can move. And here we are using the Servo Motor with the four arms horn so that we can flap both wings simultaneously

Interface the servo motor (with four arm horns) to the Arduino Uno in the following way:

• Brown Pin (Servo) → GND Pin (Arduino)

• Red Pin (Servo) → 5V Pin (Arduino)
• Orange Pin (Servo) → ~9 (PWM Pin no. 9 of the Arduino)

For the coding here I’m using the Tinkercad. You can use the same code to make your own. Click on the below link for the code.

After performing simulation on Tinkercad. Download the code by click, down-arrow under the code tab.

After uploading the code your motor is start rotating from 120 degree to 180 degree and from 180 to 120 degree with the gap of 1 degree.

First unplug the Arduino from the computer

Now stick some pieces of paper or cotton in the middle of the paper bat behind it. So that when we attach the servo behind the paper bat, there should be some gap between the paper bat and the horns of the servo. So, when the servo will rotate, it also did not rotate the face of the bat.

Now for flapping the wings with the help of servo motor needle the black thread to the both wings of the paper bat. (For more clarification you can refer to the above images.)

For more real feel of the bat you can add the eyes on the bat by drawing the eyes on the paper and paste it using tape or glue on the bat face.

Now stick the servo motor on the paper using tape by rotating it to 180 degrees. you can rotate it using your hands for sticking behind the paper bat. For more clarification see the above images.

Tie the thread of both wings with the Servo Motor horns without any looseness at the degree of 180.

See the above images to know which wing's thread should tie from which horn of the servo.

Now Plug the Arduino Uno and flap your bat.

Thank You. If you have any question regarding any thing don’t hesitate to ask. And don’t forget to share your work also.
