Progress
I tried to connect all the components together but encountered significant difficulties. When connecting the Arduino to the LiPo battery, unfortunately the pins of the Arduino unit do not fit and insert into the breadboards I purchased. I tried to perform direct coupling with jumper wires but encountered there are risks to this method. Connecting an external power supply to an Arduino without proper voltage regulation may damage the unit, even when using a battery surplus that matches within the voltage range at which the Arduino uses. I also do not possess a micro usb cord to even test the Arduino itself to my computer.
I wrote the Arduino IDE sketch to connect the Arduino unit to a mobile app over bluetooth and to communicate with the OLED screen. The mobile app is a simple, testing environment solely for exercising the BLE capabilities and to try transmitting text between each other. It is not reflective of the actual mobile app we will be employing. I have downloaded all necessary CAD models and begun creating a basic casing as well.
Next Steps
I found I did not acquire the appropriate tools and materials for this project. I will be purchasing an Adafruit Battery Backpack, a voltage regulating shield to protect the Arduino unit. I will also be getting an Arduino Nano 33 BLE Sense without headers. This model has additional sensors that will aid with testing in addition to capabilities of the Nano 33 BLE. Without headers, I will be soldering the components together. I find this process is better as its headers probably won’t fit my breadboard either. Finally, I will purchase a micro usb cable to be able to test without needing a battery source hooked to the Arduino. Everything else is still fine to use, especially the jumper wires, battery, and screens. I want to try and get at least the battery and Arduino connection as well as the bluetooth capabilities done as my highest priorities.
