Easy Arduino fun project and it makes bubbles!

This is a simple project to start with Arduino. A servo, a motor, some code and a lot of fun, especially for kids. The wooden frame is only a skeleton to keep the parts in place and therefore not suitable for kids hands.

It is possible to combine the machine with sensors and play with Arduino. I've tried an IR-remote and plan to use a PIR motion sensor in future.

Here is a PCB Adapter for an Arduino Pro Mini:

    New PCB arrived and tested. The fan speed can now be controlled by turning the potentiometer. For the battery I used a JST plug to get reverse polarity protection.

    I've added a potentiometer to the PCB to control the fan speed. The V1.0 board used a PWM pin, that does not support PWM. It is still possible to use one of the ISP pins (D11) which is directly beside the motor conector to use PWM control.

What did you use to make the red plastic ring? Did you 3d print it? Is so do you have the file.

  Are you sure? yes | no
