Questions tagged [arduino]

For questions pertaining to the Arduino microcontroller and it's integration with Raspberry Pi projects. Questions about Arduino only are off-topic and can be asked at Arduino Stack Exchange.

The Arduino is a single-board microcontroller, designed to make the use of electronics on technology projects easier. The Arduino is visually similar to the Raspberry Pi, but it is focused more on using electronics in programming, than just programming like the Raspberry Pi is (although GPIO may be used for controlling electronics).

Custom firmware on Raspberry Pi?

Is there a way to use the Raspberry Pi like an Arduino? That is, without an operating system? Just connect it to the USB of your computer and download code onto it, and the next time the Raspberry Pi boots, it runs that program (infinitely). Just as…

SPI: Raspberry PI master and Arduino slave

I'm trying to have a Raspberry PI act as a SPI master and send data to an Arduino Nano (one of the cheap clones). I partly succeeded, but I don't get a continuous communication, and some bytes get lost. I only use simple wires on a breadboard to…

Use Arduino code on raspberry pi?

I am not that familiar with the Arduino boards. For christmas, I got a sensor kit from my aunt. The source code is all for the arduino and I don't have an arduino. Is there a way I could re-compile the code into something the RasPi could use?
