Application scenario examples:
The Arduino DIY (small fan, bubble machine) is so easy and simple, without the need for extra modules. It is easy to connect and use, with forward and reverse rotation, fast and slow, as you please. List of application scenarios for bubble machines and fire extinguishers.
