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 ...

More often than not, an IoT master device uses the SPI (serial peripheral interface) and I 2 C (inter-integrated circuit) protocols to exchange data with EEPROMs or sensors that are operating in slave ...

While the Raspberry Pi has very good support for an I2C bus, a lot of very cool chips – including the in system programmer for just about every ATtiny and ATmega microcontroller – use an SPI bus.

The Raspberry Pi 4 is a true next-generation Pi, with dual-screen 4K support, USB 3.0, a new CPU and GPU, and up to 4GB RAM. The Raspberry Pi 4 is a massive leap forward for the low-cost computer, ...

Want to learn programming and robotics, but don’t know where to start? Forget expensive colleges and dull textbooks and pick up a Raspberry Pi, the super affordable credit card-sized computer, which ...
