Hardware Required

• Arduino IDE
• ESP32 board
• OLED display
• Accelerometer
• Heart rate sensor
• Buttons
• Battery
• Charger
• Enclosure

Programming

The smartwatch is programmed using the Arduino IDE. You'll need to first install the appropriate libraries for OLED displays, accelerometers, and heart rate sensors.

The program is divided into two main parts:

• User Interface: This is the graphical user interface of the smartwatch, displaying the time, date, steps taken, and heart rate.
• Sensor Data Processing: This part collects data from the sensors and updates the user interface accordingly.

Features

The smartwatch offers the following features:

• Clock: Displays the time and date
• Pedometer: Tracks your steps
• Heart Rate Monitor: Measures your heart rate
• Notifications: Displays notifications from your smartphone
• Alarms: Wakes you up at a certain time

Assembly Instructions

1. Connect the Hardware: Connect all the hardware components according to the schematic diagram.
2. Upload the Program: Upload the program code to the ESP32.
3. Assemble the Smartwatch: Enclose the smartwatch in the enclosure.

Conclusion

Building your own smartwatch with Arduino and ESP32 is a rewarding project. You can create a fully functional smartwatch that gives you real-time information on your health and fitness. Plus, it's a great way to learn more about electronics and programming.
