INTRODUCTION
- In this blog post I will be presenting my design for my Idea,
- Originally my plan was to port a project that I developed during a challenge in the Azure Sphere Group, to the Arduino Nano 33 IoT Board
- The project Beats Per Minute -- Home Is Where the Hack Is Challenge describes how I connected a Heart Rate Sensor to the Avnet MT3620 kit. The Beats Per Minute are calculated and displayed on an attached OLED Display. The RED LED will indicate the users heart beat..
- My original idea was,
- Replacing the MT3620 kit with the Arduino Nano 33 IoT Board There are pin differences between the two MCU boards. Also the LED was attached to an led header on the MT3620 kit.
- Luckily the other program is written in C, so I thought I would start there and make changes to the pin configurations. and use the same libraries.
- But after experimenting with the 2 components in Blog#2, I realized that I could use the code in the experiments to design and implement my idea. So now, that will be my new plan.
- This blog will describe the breadboard circuit with the Arduino MCU and the OLED Display. The software will also be described in a Sequence Diagram to show the flow of the logic.

Here is the Sequence logic design for software.
Libraries
The libraries are the same used in Blog#2
Conclusion and Summary
- This is a very short Blog, compared to Blog#2.
- This is because I plan on using the Wiring and Code from Blog#2 to implement my idea
- My next blog will describe the Implementation of my design.
