SunriseLight VS arduino-nRF5

Redshift has code to calculate that locally which I use in my sunrise light project

Since then I've made lots of things like audio amplifiers and effects, motor controllers, 3d printer controllers and firmware (and subsequently smoothieboard), muscle stimulators, bluetooth LED strip controllers, etc

Here's a bluetooth RGB strip controller I made a couple years ago if you want an example.

hackaday.com has a zillion links to examples; here's one two three four of mine and I've also got a laundry list of companies I've helped but whose technical details I can't legally publish (note that I've assisted many but not all of the companies in that link)

eg for this project my available inputs were intermittent 12v power, bluetooth, and the current time and location; and the desired output was 3× high current low-side switches that produced 12v RGB PWM corresponding to the colour temperature and brightness of the sky - so we need a bluetooth microcontroller, battery backup to keep time when 12v is absent, some battery management which wanted 5v in, a 12v buck to feed it, some MOSFETs, and redshift or similar code to plug into things.

Here's one I made earlier although it targets NRF52 and doesn't use Arduino libraries.

I've got a similar project here, and most of the complication is for battery management - the actual LED strip drive is even simpler than yours because I chose MOSFETs that work nicely with 3v3 gate voltage :P

If you're curious here's a couple of my AVR projects (not using Arduino libraries at all), and here's an NRF52 one

I guess my Sunrise Light project could have been built on Arduino's libraries since an NRF52 core exists, but I didn't do that…

For example, this old project of mine uses an NRF52832 (which is substantially similar to the '840, just missing USB) and it offers several services and characteristics including a battery level service, a DFU service, and a custom service for actually controlling it.

Here's two NRF52 Arduino cores ;)

I am using the nRF5 BLE Core with a generic nRF52832 chip. From everything that I have read, this core should work with my generic board and I can use the BLEPeripheral library without a problem as well.

I just purchased an E104-BT5032A-TB from AliExpress, which is a dev board with the Nordic nRF52832 BLE chip on it. I have only programmed MCUs with the ArdunioIDE and I have found a library that should work with this board. I am waiting on getting an ST Link v2, but I am wondering how to use it to program this board.

Very interesting! So just to make sure that I am understanding, I could buy a BLE Nano v2 and install the BLE Nano board into the Arduino IDE with this. Then I could use the BLEPeripheral library to create custom characteristics and services and write my sensor data to them? That sounds too good to be true! I think the real reason I didn't go this route at first was because it seemed to complex and sending AT commands to an HM BLE module seemed easier, but if this works then it will simplify everything!
