The Mega, Due, Duo, and Nano are great for bog standard data processing, but what about more unusual applications? The Arduino MKR Zero is an Arduino that is specialized for audio applications. However, they are not the only boards that are ideal for memory the Arduino M0, which is based on an ARM Cortex-M0+, contains 256KB of ROM and 32KB of RAM. The Mega has 256KB of ROM and 8KB of SRAM, while the Due has 512KB of ROM and 96KB of RAM. As with I/O, the Mega and Due come out on top. Interestingly, as a microprocessor’s ROM size increases (which holds the code), the RAM usually increases in size as well (this holds your variables and temporary data). More advanced projects may rely on large programs that use a lot of memory-both RAM and ROM. But, only the Mega has analog outputs (2), which could be vital in a project that needs to produce an output analog signal, such as a function generator. But not every project needs digital pins analog pins are just as important! Both the Mega and the Due have analog input pins-the Mega has 16, whereas the Due has 12. If your project relies on many I/O lines, then you may want to look at the Arduino Due or the Arduino Mega, which both boast up to 54 Digital I/O pins. However, simply choosing a more powerful device might not be the solution to your project, so which board should you pick? I/O While the Arduino Uno and Nano can accomplish an astonishing number of tasks, you will inevitably want more power and functionality. The Nano is also very small (18mm by 45mm), and it’s ideal for situations where portability is important. This makes it optimal for those who are already electronic-savvy and who already have breadboard circuits ready. The Arduino Nano has most of the same features (with the exception of a smaller USB port and no DC power jack), but it is better suited for projects using breadboards. The Arduino Uno is one of the most common Arduino boards available, and it has some user-friendly features, including large 2.54mm pitched sockets for connecting to external devices, an onboard LED, inbuilt power handling (such as an external DC power jack), and a large USB B connector for connecting to a PC. If you are new to the Arduino, then there are two devices that immediately come to mind: the Arduino Uno and the Arduino Nano. So, when selecting a development board for your project, which one should you go for? Featured Devices Some have more IO pins, some have fewer peripherals, some are cheaper, and some are faster. While most of these boards are based on ATMEL devices (now a subsidiary of Microchip), they have some different capabilities. The word Arduino refers to an entire family of single-board microcontroller development boards, which are convenient for prototyping and building projects. But which Arduino should you use for your next project? The Many Flavors of Arduino The Arduino IDE runs on a subset of C++ (or a superset of C).In our previous blog post, we briefly looked at the Arduino IDE. In short, learn some C and the basics of C++ if you like. You would end up having to write a custom library in C, then build a Python library from it, use it, then compile back to C again. And this will be something you use fairly frequently with Arduino, depending on your projects. For example, when you learn about C’s volatile keyword, you’ll see that it’s probably not even possible to emulate that functionality with standard Python. If you type a few lines of code, you can be pretty sure they won’t be optimized to do something slightly different. C also has very little magic “behind the scenes”. They have mechanisms purposely exposed for reading from and manipulating hardware registers - which is how you interface with the hardware (like the Arduino). In this case, C and C++ were chosen for the Arduino for a reason. Debugging anything would be an exercise in pain tolerance.Īt the root, the standard python language won’t work so well, largely because you won’t have access to many of the Arduino libraries that are essential for working with the hardware. Your build-test loop will also be horribly ugly. Not to mention you’ll have next to zero support from any community. But you’re likely to have a higher learning curve doing that that and learning Arduino specific stuff and the hardware side all at the same time. Python can be compiled to C and - at least theoretically - be used in that way for Arduino programming.
Note: My knowledge is from 5-6 years ago, things may have changed since then. It can be scary at first, but it is the correct tool for the job.
Taking the time to learn the basics of C will be the best way to go here. No, Python will not be suitable for Arduino programming.
