This video shows how to vibration motors, also called eccentric rotating mass (ERM) motors, with an Arduino. They are available in different sizes and shapes, including the "coin" or "pancake" variety. They are a simple way to add vibrations, for example for haptic feedback, to your Arduino projects.

Thanks, I dont code with Arduino but your examples and commentary is teaching me so much stuff I can apply to my raspberry pi projects etc, thanks for the comprehensive, no steps skipped, tutorials
Thanks! Many of the digital devices we cover in our tutorials could also be connected to a Raspberry Pi's GPIO pins, so at least the circuit part should be very similar if not identical.
thanks for the video
you deserve more attention
Hello, I would like to redo this tutorial at home, but I would like to know the reference of the Mosfet used as well as that of the vibrating motor. thank you
cool beans.
I think tinkerCAD might be throwing an error because there's not any voltage protection on the back end of the motor to prevent inductive spiking.
Although you're talking very small currents, inductive voltage spikes can be either positive or negative, and if you don't have a method of preventing that voltage from feeding back up into the arduino, in theory it could be a problem.
Like ya said in the video, since it's a circuit simulation, theory is the only thing that matters there, but you might be able to get around it by adding a small diode off the tail end of the arduino ground pin to battery ground pin.
Hello. Firstly, I really appreciate your content. I'm curious if it's possible to make it work adding a single 9V battery as an external source. I intend to operate it with a 7V vibration motor (similar to an ERM) since that's what I have available at the moment
Hi - in general 9V batteries are not a great choice for running motors since motors require a lot of current and 9V batteries drain pretty quickly. They work better in longer-term, low-current applications. It will work if you are only going to vibrate the motor occasionally though. We have an additional video about using an Arduino with external power supplies here: ua-cam.com/video/XrJ_zLWFGFw/v-deo.htmlsi=3NdMPCNO03xuBYfg
@@Science.Buddies Thank you so much for your guidance, sir. I'm a newbie, but after watching your second video, I was able to make it work. Keep up with these great videos!!
Hi, how can I apply this to make a wireless version?
can i use the motor directly with the arduino like i use my LED?
No, the Arduino pins can only supply 20 milliamps (mA) and the motors can use up to 100mA.
How can I mount a circuit with a bunch of motors that react with an Audio Signal?
See our tutorial about microphones here! ua-cam.com/video/bMs5J4bJOD0/v-deo.htmlsi=vJ1ZQC8b9i-Ovyoh
Are parameters of this transistor important?
For such a small motor in general you are not too worried about the parameters of the MOSFET, since even small N-channel MOSFETs can be rated for dozens of volts and amps. For example this one is 30V/60A which is WAY more than this little motor needs: www.adafruit.com/product/355
Please, make video on it
We don't have that, but we do have this quadruped robot with 8 servo motors! ua-cam.com/video/tCtgt-VoPUk/v-deo.htmlsi=cyJqc7YIXB4EVYAf
What kind of motor do you use for this application?
If you search online for "vibration motor" or "pancake vibration motor" you will find many options.
@@Science.Buddies does your motor works at a nominal voltage of 5V?
Many of these small motors are rated for 3V so it depends on the motor. In that case you can use an external 2xAA battery pack instead of the 5V from the Arduino.
