Arduino that can vibrate - student project

Projects General Guidance
1

Hi!

My name is Sara and I am currently a student at Stockholm university. I am doing a project with my group where we want to create a bracelet that can vibrate on command. I have no experience of Arduino and very little of programming as well, and was wondering if this would be possible to implement with the Arduino?

We were thinking of a smartphone that could send the message to the Arduino to vibrate and then maybe just taping it on to a clock or something?

Is there any smaller Aurdino that would work for this purpose?

Thank you for any suggestions!

Very nice regards,
Sara

Welcome to the forum

Your topic was MOVED to its current forum category which is more appropriate than the original as it is not an Introductory Tutorial

tl;dr: start simple with simple programs that will be part of the final device

Your device will need an Arduino, some means of receiving messages, a way to vibrate and… some source of power for all that.

Your device will need some slightly less than trivial programming.

If your group are all beginners in the areas of expertise that might be required, the project of a portable bracelet is ambitious but not impossible.

I suggest you start with a non-remote controlled non-portable not wearable not battery powered version. As simple as something that will light an LED for 5 seconds when you press a button.

No time you take getting that to work will be wasted.

For getting the signal from the world there are a few choices. Some Arduino boards have build in Bluetooth, or can have a Bluetooth module attached. This would be the least you'd need to "hear" from a cellular telephone.

In parallel with getting the communication to work you can think about battery power. Some Arduino boards are already equipped to accept the power of one cell; some can charge such an attached cell, but that is not important.

The vibration can come from a vibrating motor like those found in phones. That will require a bit of circuitry as Arduino boards can certain control such a motor, but not provide the power it might take.

Still not portable, still not battery powered. But a long way down the path.

Sry no specific hardware recommendations - all I can think of will end up being a bit clunky, maybe a real fashion statement. :expressionless:

And I make no sense of this

send the message to the Arduino to vibrate and then maybe just taping it on to a clock or something?

Is this clock with the Arduino taped to it on my wrist or what?

The arduino itself cannot vibrate. For your project, you can use an Arduino lilipad and Lilypad vibe motor.
The lilypad is a wearable arduino UNO.

The vibe board is a wearable board. It has an on-board vibration motor. You can sew the motor to the lilypad with conductive thread. I myself made a sunscreen reminder hat using these two products.

If it's a must to use an Arduino and learn more about electronics, then you are in the correct place. If it would also be ok to "only" program without learning electronics, you might want to check the Bangle.js smartwatch, or actually any programmable watch or armband that can vibrate. I have some personal experience with programming Arduino and Bangle, even communicating between them through Bluetooth.
Regardless of what you choose, I recommend starting with small steps, learn how to blink a led, write a "Hejsan världen!" message on a display or something similar, and then later take on more advanced topics.
