Understanding the project architecture
In the preceding sections, we discussed the sensors and development board in detail. Now it’s time to get started on the recipe. In hardware development, before we start working with sensors and development boards, we need to develop the design concepts to get a better understanding of how things will be connected. There are many pieces of software available to design and develop design concepts for electronics projects, but we are going to use Fritzing.
In the following two subsections, we will cover schematics and project design, explaining how to connect the pins to the development board and soldering. Next, we will do some calibration of the pulse sensor fetch-reading threshold, as this is different for different development boards. This is very important to do before we send the data to the cloud.
Schematics design and assembly
The purpose of design is to get a clear understanding of how the sensors will be connected to the...
