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.

When connecting an original Raspberry Pi A or B, those I2C pins need to be wired to the Pi’s single I2C bus. ... we used Python and Flask to send requests to the Raspberry Pi wired to the garage ...

The Raspberry Pi I2C Multiplexer is particularly useful in scenarios where multiple I2C devices need to be connected to a single Raspberry Pi. For example, in a home automation system, ...

Raspberry Pi's Python project path is split into six parts, beginning with three 'Explore' projects in which learners are introduced to new coding skills through guided tasks.

The latest board from the team enables you to have up to 4 I2C busses connected to either your Arduino development board or Raspberry Pi mini PC and is also equipped with Grove Connectors and LEDs.

Raspberry Pi is releasing a new piece of hardware, which lets you put the modular, inexpensive computers into Lego robots and use them to control motors and sensors. It feels like an obvious choice.
