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 ...

As for UARTs, the Raspberry Pi’s one-and-a-half UART interface has long been an issue in robotics and home automation applications.

The Arduino can also read from an analog sensor, which can't be done on the Raspberry Pi. The Raspberry Pi is a microcomputer you can write code directly onto the device.

How do Arduino and Raspberry Pi compare? We break down both sides of the DIY story and provide examples of why each may be best for your particular project.

• Level Shifting for SPI, I2C, UART between Arduino Uno & Raspberry Pi. • Temperature Sensor. • Dual Bridge motor driver which can drive motors up to 1Amp.

The Raspberry Pi and Arduino are designed to be easy-to-use platforms for DIY electronics projects, but there are a few key differences.

However, the Arduino can achieve several things that a Raspberry Pi can't. Arduino and Raspberry Pi models are both affordable, and there are many Raspberry Pi projects that won't break the bank.

element14 today launched the low cost triple-play Embedded Pi platform that bridges the massively popular design worlds of Raspberry Pi, Arduino and 32 bit embedded ARM.

There are some cases where picking between the Raspberry Pi and an Arduino are easy (like when Linux is involved), but oftentimes it’s hard to make a choice between the two.
