is categorized as one of the most influential hardware and software development companies worldwide. Which has been essential in the maker movement that represents a great extension of the DIY culture. Because, in addition to providing different models of printed circuit boards, we also Y a great community that tirelessly develops different projects.
Therefore, Arduino It is characterized by being the main base of what concerns both simple projects and the most advanced ones. Therefore, in addition to offering numerous electronics and robotics alternatives, It has also delved into what wearable technology is. Being this, a great milestone of the scientific revolution that managed to open a new personal universe.
In this sense, today various wearable projects with Arduino are known that you can do yourself to obtain a powerful device without investing a large amount of money. Therefore, in this post, we will focus on explaining What are wearable projects about and which have been the best developed by Arduino?until now.
What is a Wearable and what are these projects for?
Translated into Spanish, wearable means “wearable” or “wearable” and this term applied to the field of technology, acquires the meaning of “wearable or wearable technology”. In this way, it consists of a project based on small devices that are incorporated into the human body and continuously interact with some part of itwith the aim of carrying out a specific function.
In such a way, for example, these smart watches or bracelets, shoes, belts, glasses, rings, headphones, t-shirts or socks that emerge as wearable projects, They serve to control the state of health of the user, basically. Whether it is based on measuring the pulsation, computing the heart rate, showing the sensation of well-being or being, counting the hours you sleep, etc.
This is very helpful and reveals some advantages, such as:
- They are capable of capturing some physical magnitude around the human body or the world that surrounds the user to convert it into digital data that can be viewed, stored and controlled.
- Facilitates daily life of all its users.
- It is a technology that great comfort because it has a small size and goes “united” to the person’s body.
- supports an optimum level of customizationaccording to the needs of each user.
- As usual, group different tools in a single device. Be it work, communication, health and leisure.
For its part, it is necessary to note that wearable projects are possible thanks to the fact that incorporate a microprocessor together with specific sensors and a GPS system from which these devices manage to determine the position of the user and also connect to a computer or smartphone to be able to be controlled through wireless technologies (Bluetooth or Wi-Fi).
List of the best 10 wearable projects with Arduino that you can do yourself
We have reached the section in which we will show you several wearable projects with Arduino which are quite interesting. But, before mentioning each one of them, we want to highlight that, in order to consider a quality wearable project, It is valuable to approve three essential requirements of this technology.
Which are:
- The size: To set a device as wearable, it is essential that it has a small size to be able to integrate it into the human body or into clothing. So small enough Arduino boards are needed to achieve this.
- A complete integration: In addition to meeting the requirement based on tiny size, it is also essential that the device can be easily integrated with traditional clothing. Since, for example, the plate It’s small, but it’s hard to integrate like that.
- a low consumption: It is also relevant to use an Arduino board whose consumption is as low as possible. Which means that, wearable projects they have to take advantage of the evolution of batteries. Well, it’s not practical to build such a bracelet that requires a car battery as a power source.
Now, having clarified all of the above, we proceed to specify which are the 10 best wearable projects that can be created from Arduino to maximize the DIY culture (“do it yourself”):
Portable and wireless heart rate monitor
It’s based on a heart monitoring project that is “wearable”, due to the fact that it is worn directly on the wrist (as a kind of watch) and it is wireless. In this way, it works when running, walking, driving the car, etc. Taking into account that, in addition to measuring data and calculating BPM in real time, it also has the ability to transmit all this information through a radio protocol which is compatible with the generic nRF24 chip.
For its part, in order to implement it, it is necessary to buy an Arduino Nano R3 board, a uEGG device to measure the actual BPMa generic nRF24 module to save money, a LiPo battery, or any battery with more than 200 mAh capacity and an Adafruit NeoPixel ring. Besides, a generic soldering iron and the Arduino IDE to be able to program the system.
Indicator jacket for cyclists
It refers to a jacket with lights that can indicate the direction that a certain cyclist is going to take so that other cyclists or cars are aware of your movements, in order to acquire greater security. This was implemented using a special Arduino board that is known as “LilyPad” and is designed to be easily integrated into any garment. That being the case, the best Arduino alternative for Wearables for a cost that does not exceed 30 euros.
In that sense, to be able to create this jacket, the LilyPad plate must be sewn and integrated into the jacket and, thanks to the fact that it is specially prepared for this, it is not uncomfortable. Among other details, it should be noted that there is the possibility of program the garment in the Arduino IDE with a specific code offered by the designer, to load it in the LilyPad. Thus, you can decide the behavior you want for this jacket, customize its flashing patterns, etc.
For his part, The materials needed to carry out this project are: a LilyPad Arduino board, a LilyPad power supply, a mini USB cable, an FTDI connector, a spool of four-layer lead wire, and two pushbutton switches. Also, 16 LilyPad LEDs, the jacket on which you will work, two needles, a pair of scissors and a sewing machine (optional).
Smart assistant for the elderly
It refers to a virtual assistant that can be adjusted around the arm in the form of a band, just as a bracelet is used. Which, mainly, was designed for Alzheimer’s patients and the elderly in order to help them cross the obstacles of their daily life independently. Thanks to that, it will prevent them from having serious accidents when they lose their balance because the wearable device is able to detect a sudden pressure drop in order to alert the relatives and not let the injury worsen.
Added to that, encourages older people to exercise in a constant way, motivating them by showing them the time they have walked and the number of steps they have taken. Even this smart assistant in the form of a bracelet manages to measure people’s temperature to alert others if you have a fever, for example. In addition, it shows the relatives the status of the elderly; whether he is awake, sleeping or exercising.
To create such wearable equipment, the materials used are the following: An Arduino Nano R3 board, the Infineon DPS310, Espressif ESP8266 ESP-01, a 3.7V LiPo battery, and various jumper wires that may be generic. Additionally, regarding the software, the Arduino IDE and an application known as “Blynk” are required.
color ring
It refers to a ring that has the ability to measure light intensity and ambient color to display it from three available outputs. That is, these measurements They are presented by means of three colors (red, green and blue) that emit three vibrations directly from the motor. Thus, an intelligent system that manages to activate when each user presses the indicated button and this, is ideal for conserving wearable device battery life designed to fit like a ring.
In order to build a comfortable device for people, It is recommended to use the Arduino Pro Mini board, since it has a tiny microprocessor. In addition, it is necessary to buy the following supplies to implement the project with total quality: a 100mAh Li-Ion battery, a BS170 Mosfet semiconductor, an Adafruit RGB sensor, a 100 ohm resistor, a push button, a 3D printer and a soldering iron.
Ultimate Cough Acknowledgment Bracelet
In this case, takes care of recognizing cough so you can stay away from it at all times. Thus, mainly, this project It is characterized by being usable, comfortable and lightas well as, for providing different functionalities in a practical way and for teaching individuals to be more aware of their environment.
In this case, Various materials are also required which are: an Arduino Nano 33 BLE Sense board, an Adafruit vibration motor, an Android or Apple smartphone, jumper wires (generic), a rubber case, a rope and a soldering iron.
Apart from that, this project requires the use of the Arduino IDE and, at the same time, of nRF Connect services and Edge Impulse Studio. This, in order to program the cough recognition bracelet correctly. Fortunately, both the Arduino software and the nRF Connect can be downloaded for free and, likewise, the Edge Impulse Studio is an online service that allows you to open an account without any cost.
back to the future shoes
Certainly, it is a project that, although it is not fully wearable, is wearable by people and is of great interest for what it manages to do. In view of the fact that they consist of slippers that add motors and have the ability to tether themselves. Thanks to the fact that, through a force sensor that manages to read the pressure of the foot, two servomotors are activated that apply tension to the laces and manage to adjust the shoe. For this reason, they are known as “Sneakers from Back to the Future”.
To carry out this project by the hand of Arduino, a board of this type is required that use the motor protector “Duemilanove”, like, a high and padded shoe with loose interior, a force sensor, two servomotors, an LED, a pair of resistors and a sheet of metal approximately 4×4. As well as insulated copper wire, a 9 volt box with a switch and a built in battery clip10 1/8” braided nylon paracord and 1/2” plastic cable loops to organize cables.
