CircuitPython nRF52840 BLE Client / Server Remote Control Tutorial

This CircuitPython tutorial demonstrates how to build a battery powered Bluetooth BLE client remote control to operate a BLE server peripheral hosting a solenoid and a spectrally selective light detector.

All the code, schematics, notes and updates are available on my website:

This is the 5th video in my CircuitPython tutorial. Here's a link to the full playlist:

Thanks for the video. Very well explained. I have not done any projects with Bluetooth, this was very informative

All of this info about LED's is fantastic. I absolutely must source and try using defraction grading now. That is an awesome technique.
Where could one learn about this kind of thing independently? Does anyone have suggested book references (especially older books or revisions that might be sourced on the second hand market)?
Thanks for such a remarkable set of examples and solutions to a simple problem.

I would love to see something showing a connection between an NRF52 and a raspberry PI to translate data back and forth over bluetooth

Thanks for the great video. I wonder if you are still interested on MicroPython for the ESP32.

Cool project. Great code walkthrough and explanation.

Awesome video, i really like your channel. Is there already a way to build a BL mesh with circuit python?

bro, I want to ask but this is out of the topic of this video. can the detection value of tensorflow be used as output on the LCD using raspberries? for example I want to detect money objects with a nominal of 1 dollar and several other nominal, after tensorflow can distinguish which one dollar and which other nominal, can the results of this detection be issued on the LCD with raspberries? so the output on the LCD is "1 dollar"?
