Smart watch Electronics projects Circuit Diagram RetroBand is the second result of Arduino Wearable Project that is supported by open source. I think this shouldn't be called a 'smart band' since it has only simple features. Actually, it's rather to be called an "Activity Tracker"โฆ But the term 'smart band' is more familiar to me, so I just call it a smart band.

Welcome to the world of fitness tracking! With the increasing popularity of wearable devices, such as fitness trackers, people are becoming more conscious about their health and physical activities. While there are many fitness tracker options available in the market, building your own can be a fun and rewarding project.
How To Make A Wearable Fitness Tracker? Circuit Diagram
Now we are going to build our fitness tracker project. In this step, we are going to connect all the suitable modules that are required for the fitness tracker to function. I suggest you check out the video for this project before doing the connections as it will help you understand the connections better.

Circuit diagram of the smart wearable health monitoring ring built around nodemcu ESP8266 microcontroller is shown in Fig. 4. The other components include MAX30100 pulse oximeter sensor, temperature sensor LM35, a small pushbutton switch for triggering an SOS message, an LED for on/off indication, and a tiny 3.3V battery.
