How can i make a wireless vibration motor?

Hello!

I am trying to make a wireless vibration motor for deaf people but I have no knowledge about this.
I want it to work as the same as the alerting device for deaf people.
Such as,
When I press a button once, the other part of the device (which is not connected with wires) vibrates once. and pressing twice - vibrates twice. and this goes on until the 5th.
One person who has the motor is going to press the button, and the other person who is around that person can receive the vibration through a device.
I want it to be portable and if possible, wearable, like apple watch?
if that’s too much work, it can just be a size of something that can put into a pocket.

How can I make this? what kind of materials will i need?
Please details step by step. Thank you very much!!!

Hello @help_pls and welcome to the RobotSHop forum,

For wireless communication you can use radio, Bluetooth or WiFi, you can find lots of options in the Data Telemetry section of the store. A great option would be a small microcontroller with wireless capabilities, for example a ESP32.

In order to make it portable on both ways you’ll need two mircrocontrollers, one with a push button that will send the signal and one that will receive the signal and activate the vibration motor. Or if you want you could create an app and control via bluetooth or wifi on your phone or a webpage and control it via wifi.

If you use two microcontrollers the project would be similar to this one:

But with a vibration motor instead of the speaker.

If you preffer the app option it would be like this one:

Or with a web page

Oh and since you mentioned wearables I thought I should point you to the DIY Wearables section, there you can find some nice microcontrollers that can be easily sewn (just make sure you choose one with wireless features), as well as some wearables components such a battery holders, LEDs and sensors.

I hope that helps!

Hello, what if I want to use this in the middle of the mountain? will the two microcontrollers work? Can you explain how they work? Just brief explanations about the science… Sorry this isn’t my course that i don’t really have knowledge on this… :cry:

Yes, you could use Bluetooth. Unless the devices are too far away from each other then you’ll need something else, a good option could be LoRa.

Can you explain how they work?

It depends on what you’ll use (Wifi, Blueooth, etc).

thank you for the information!

I am trying to use bluetooth, can you explain how they work please?

Here’s an explanation of how bluetooth works:

How do Bluetooth devices work? - Scienceline.

And here you can find an example of two way communication between two ESP32
