Hello,


I want to connect a vibration motor (e.g. 
https://paradisetronic.com/de/aktuatoren/mini-vibrationsmotor-1-5-5v) to 
a laptop and control it with a software. The manufacturers of the 
software suggest Chronos for this 
(https://support.pstnet.com/hc/en-us/articles/115003480968-INFO-Chronos-and-Triggers-24492-). 
I'm new to electronics and hardware, but I've tried to teach myself the 
basics with Arduino :)


If I've understood it correctly, I need the I/O Cable and then use Pin 1 
(+5V) for one cable of the vibration motor and Pin 5 (Analog Ground) for 
the other one? Is it that simple or have I forgotten something?


Thank you in advance & regards!

Note that even this little motor draws more current than the pin of the 
Arduino can deliver. You need to add a driver transistor controlled by 
the Arduino to drive the motor:

The 'Schaltstufe für kleine Lasten' is what you need.
Don't omit the Diode. Your motor is a inductive load like the relay and 
needs the same circuit.
