Keywords

💡Sensor Orientation

The orientation of the sensor is crucial to ensure it works correctly with the Arduino. In the video, the SDA and SCL pins on the sensor need to be correctly aligned with the analog pins on the Arduino Nano. This step is essential for the proper transmission of data between the sensor and the microcontroller, as misalignment could result in malfunction or incorrect data readings.

💡Arduino Nano

The Arduino Nano is a small microcontroller board used to control and process data from various sensors and modules. In the video, it is central to the DIY health band, acting as the brain that connects the pressure sensor and Wi-Fi module. It receives input from the sensors and can communicate that data through the Wi-Fi module, forming the core of the wearable tech setup.

💡ESP8266 Wi-Fi Module

The ESP8266 Wi-Fi module enables wireless communication for the Arduino Nano in this project. It allows the health band to transmit data wirelessly to other devices. Properly connecting the module's pins to the Arduino is essential for establishing this wireless connection. This module is critical in transforming the health band into an IoT (Internet of Things) device.

💡DPS 310 Pressure Sensor

The DPS 310 pressure sensor is used to measure atmospheric pressure, which could be important in health monitoring for tracking changes in altitude or barometric pressure. In the video, this sensor is soldered and connected to the Arduino Nano, forming one of the key components of the health band. Its accurate orientation and connection are necessary for correct data collection.

💡Breadboard

A breadboard is a prototyping tool used for assembling temporary circuits without the need for soldering. In the video, the breadboard is used to hold and connect the sensors before soldering them permanently. This makes it easier to test the setup before committing to final connections. It is especially useful in educational or DIY projects where testing is essential.

💡Velcro Straps

Velcro straps are used to hold together and secure the components of the health band. In the video, the Velcro straps are wrapped around the canvas and foam that embed the components, ensuring the band stays comfortably on the wrist. These straps allow for easy adjustment and provide a flexible, wearable solution for the DIY project.

💡Canvas and Foam

Canvas and foam are the materials used to create the structure of the DIY health band. The components of the health band, like the Arduino Nano and sensors, are embedded in foam, while canvas gives it a durable outer layer. In the video, these materials are chosen for their flexibility and comfort, making the band suitable for everyday wear.

💡Soldering

Soldering is the process of joining electrical components together by melting solder around them. In the video, the user needs to solder pins onto the sensors and modules to create permanent connections. This step is essential to ensure stable electrical pathways between the components, making the DIY project function reliably.

💡Pin Configuration

Pin configuration refers to the specific way in which the pins on the sensors and modules are connected to the Arduino Nano. In the video, correct pin configuration ensures proper communication between the pressure sensor, Wi-Fi module, and microcontroller. If the pins are not properly aligned (e.g., SDA to Analog 4, SCL to Analog 5), the setup will not function as intended.

💡Battery Slot

The battery slot is a small space embedded in the foam of the health band to securely hold the battery. In the video, this slot ensures that the battery is safely tucked into the band, protecting it from damage and ensuring that it stays in place during wear. This also contributes to the neatness and comfort of the final design.
