Researchers have developed a low-cost visible light communication (VLC) system using commercially available hardware that ...

Scientists have revealed a futuristic 'communication with light' system that uses light pulses instead of radio waves to ...

We’ve gotten used to the GPIO-available functions of Raspberry Pi computers remaining largely the same over the years, which is why it might have flown a little bit under the radar: the Raspberry Pi 4 ...

We’ve seen a ton of projects that interface hardware with the Raspberry Pi. But they usually depend on bit-banging. That means they toggle the pins in software to match a specific protocol. The thing ...

Serial Peripheral Interface (SPI) is an inter-device bus protocol that provides fast, synchronous, and full-duplex communication between a master and one of several slave devices. The master device — ...
