I would like to share my first steps with the Grove 'plug & play' components. This is primarily a Vibration Motor. The sketch make noise and a big vibration.
I am surprised at what the small engine is doing in this way.
Once the Grove Base Shield is plugged onto the Arduino Uno R3, the Grove's universal cable can be used to connect the LEDs to port D5.
This short introduction reflects the available original example of Seeedstudio.
