Hey hey, calm down, have some fresh air here. The Grove – Mini Fan v1.1 can be set up in seconds and bring you some nice and cool air in the hot days. It has four parts, a mini fan, a DC Motor, a DC motor driver and a Grove cable. The cartoon-style fan design makes it good choice for decorating your little LEGO house as well.
The motor driver boards have a built-in programmable microcontroller that uses Arduino IDE. In default, it is programmed to drive DC motors with analog inputs, and the rotate speed depends on the value of input signal. You can simply connect up all the parts and plug it into a controller board that has Grove interfaces, upload some code and you are ready to make it spin.

Hi there~ A4 is not connected, so you just need to control A5, yes, you can use PWM, or you can just use digital pin to control the on/off. Thanks for your time and interest in Seeed.
Hey Kaled~ You need a control board seeeduino V4.2 will be OK # https://www.seeedstudio.com/Seeeduino-V4.2-p-2517.html # ; then you need a button with grove interface # https://www.seeedstudio.com/Grove-Button%28P%29-p-1243.html #. Now use the button as a input and the mini fan as an output. If you have any tech problem please contact us through email # email@example.com # regards
