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.

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 ...

I2C makes connecting multiple sensors to a Raspberry Pi straightforward by sharing just two pins for communication. With proper setup, scanning, and coding, you can integrate dozens of devices on a ...

Raspberry Pi Pico is a cute piece of hardware. It has a powerful dual-core RP2040 microcontroller that offers 2MB (up to 16MB) Flash and 264K SRAM memories. But what truly sets the Pico apart is its ...
