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.
