đ Connecting the Sensor to the Arduino
This paragraph details the orientation and connections for integrating the sensor with the Arduino Nano. It specifies the pin configuration for the SDA (Pin 1, connected to analog pin 4 on the Arduino) and SCL (Pin 2, connected to analog pin 5). The GND pin (Pin 8) of the sensor is connected to the Arduinoâs GND. The diagram referenced helps clarify the physical connections needed for this setup.
đ¶ Wiring the ESP8266 Wi-Fi Module
Instructions for connecting the ESP8266 Wi-Fi module to the Arduino Nano are provided. Pin 1 of the Wi-Fi module connects to digital pin 11 on the Arduino, while Pin 2 connects to digital pin 10. The GND (Pin 7) and power (Pin 8) of the module connect to the GND and 3.3V pins on the Arduino. The visuals indicated in figures help ensure correct module orientation and pin connections.
đ ïž Preparing the Sensor for Assembly
This section explains the initial steps before setting up the hardware. Users are instructed to solder pin headers to the DPS310 pressure sensor, making it easier to integrate using a breadboard. The importance of proper orientation (port facing down) is reiterated, with a recommendation to use visual aids for better clarity.
đš Assembling the DIY Health Band
The steps for assembling the wearable band are outlined here. The components (Wi-Fi module, Arduino Nano, and pressure sensor) are small enough to fit on a wrist. The band is made from canvas and foam, with Velcro strips used to secure everything in place. Visual aids are referenced to help with the step-by-step process, providing a more organized and compact design.
đ© Finalizing and Testing the Band
Final assembly steps include cutting foam to the appropriate size, arranging and embedding the components, and securing everything with Velcro and hot glue for a neat finish. Afterward, the connections are soldered, with the pins carefully aligned and tested for functionality. The back of the band conceals the wiring, ensuring a clean look and efficient operation.
