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: https://www.rototron.info/circuitpyth... This is the 5th video in my CircuitPython tutorial. Here's a link to the full playlist:    • nRF52 CircuitPython Tutorials   Adafruit reached out to me and told me they liked my tutorial. They offered to pay me a small fee to publish it on their website: https://learn.adafruit.com/circuitpyt...
