A delightfully over-engineered solution to an unusual modern problem! Use Bluetooth peripherals with Bluetooth-disabled computers. This project creates a Bluetooth USB HID relay using a Raspberry Pi ...

Bluetooth is everywhere, but it’s hard to inspect. Most of the magic is done inside a Bluetooth controller chip, accessed only through a controller-specific Host-Controller Interface (HCI) ...

Abstract: One significant challenge in research is to collect a large amount of data and learn the underlying relationship between the input and the output variables. This article outlines the process ...

A low pulse on this pin (below 1/3 of VCC) sets the internal flip-flop and makes the output go HIGH. When the voltage on this pin reaches 2/3 of VCC, it resets the flip-flop, and the output goes LOW.
