Anyone who is into electronic DIY is likely to be relatively familiar with both Raspberry Pi and Arduino, and many even assumed that the introduction of the Raspberry Pi made the Arduino obsolete. However, this is really not the case, with the Arduino still pulling ahead in its suitability for certain tasks.
Here’s a quick breakdown of each model:
Essentially a fully functional computer, with a dedicated processor, memory, HDMI input, and graphics driver. It runs on a Linux operating system, making it very easy to install the majority of Linux software. It comes with a large community of support, plus a multitude of expansion chips. It does lack internal storage, but you can always use an SD card.
Arduino boards are micro-controllers rather than full computers, and don’t run on a full operating system. Instead, they simply execute written code. This means that you sacrifice access to the basic tools of an operating system, but the Arduino is much easier for executing simple code. Its main purpose is to work with sensors and devices, so it’s great for other devices and actuators.
If you’re not sure whether Arduino or Raspberry Pi is the right option for you, try considering the following points:
- Portability: This will always be an issue with Raspberry Pi since it needs more than a couple of batteries. Constant power is required, so you’ll need to carry additional hardware and set up a power supply. In contrast, the Arduino can run easily on a battery pack.
- Connectivity: The Raspberry Pi comes with a built-in Ethernet port, so you can connect to a network with little fuss and bother. It’s also easy to connect to Wi-Fi using just a USB dongle and installable driver. The Arduino isn’t made for such effortless network connectivity; you’ll need to pick up an extra chip outfitted with an Ethernet port, then do some wiring and coding.
- Sensors: It’s far simpler to connect analogue sensors to the Arduino thanks to its microcontroller. On the other hand, the Pi demands additional software to interface with other devices, and it might be overkill for many of them.
