So you have a great idea for automating your garden sprinkler system using moisture sensors or want to prototype the next IoT healthcare wearable. Where do you begin?
The answer likely includes a compact circuit board about the size of a credit card – commonly known as a microcontroller. They serve as an accessible playground for custom electronics and smart devices.
In this beginner‘s guide, we compare two extremely popular options – the Raspberry Pi Pico and Arduino development boards.
I will walk through their background, capabilities, pros/cons and guide you in deciding which matches your project needs best. Time to turn ambitious ideas into reality!
A Brief History of Pi and Arduino
The iconic blue Arduino boards pioneered the concept of microcontroller development platforms when the project started in 2005. Their goal – allow anyone to quickly build programmable circuits for real-world devices without deep electronics expertise.
Over 200K+ official Arduinos are manufactured every year along with a flood of derivatives and clones. From students to professional engineers, they cater to an incredibly wide user base. Multiple variants exist – Uno, Nano, Mega etc. optimized for factors like size, connectivity options and processing power.
The Raspberry Pi took a different path starting in 2012 by providing tiny, affordable, single board Linux computers. Their $35 Pi helped power DIY media boxes, micro web servers, robot brains and more.
In early 2021, the immensely popular Pi line took its first step into microcontroller territory with the Pi Pico. Costing just $4, it packs a surprising punch with a dual-core processor and ample IO options.
Both platforms enjoy wide community adoption and online tutorials for beginners in electronics and programming. But which one is right for your next project?
Pi Pico vs Arduino – Feature Comparison
Before picking a development board, it is important to assess if they support the core features your project requires – speed, memory, connectivity options, operating voltages etc.
Here is a handy comparison table highlighting the capabilities of a Raspberry Pi Pico against the popular Arduino Uno Rev 3 board:
| Feature | Raspberry Pi Pico | Arduino Uno Rev 3 |
|---|---|---|
| Release Year | 2021 | 2010 |
| Processor | RP2040 dual-core Arm Cortex M0+ @ 133 MHz | ATmega328P 8-bit AVR @ 16 MHz |
| CPU Architecture | 64-bit | 8-bit |
| RAM | 264 KB | 2 KB |
| Storage | 2 MB flash | 32 KB flash |
| Digital I/O Pins | 26 GPIO pins, inc. 4 analog | 14 Digital (6 PWM) |
| Analog Input Pins | 3 pins – 12 bit ADC | 6 pins |
| Max Operating Voltage | 5V | 5V |
| Wireless | – | – |
| Starting Price | $4 | $23 |
Prices listed are official recommended retail from the respective foundations. Actual retail pricing maybe different.
In terms of raw specifications, the Pi Pico beats the venerable Uno across processing power, memory, IO pins availability and price by a huge margin. Wireless connectivity remains a notable gap if your application requires it.
But electronics involve more than just specs. Let‘s evaluate overall usability across these platforms.
Ease of Getting Started with Electronics
Doing anything meaningful with these boards requires programming them using code. Both platforms come with options ranging from kid-friendly drag and drop interfaces to pro-level languages.
For Arduino boards, the official Arduino IDE is the easiest starting point. It uses a simplified C/C++ framework that beginners pick up quickly. All you need is a Windows/Mac/Linux computer. Their online editor requires no downloads at all!
Stuck on a programming challenge? Arduino‘s vibrant community forums contain answers for virtually every common question. Tons of existing unofficial libraries add useful capabilities. For example, connecting IoT sensors and machine learning.
Raspberry Pi chose Python as the main language for Pi Pico given its popularity in ML/AI applications. Their official Pico SDK also uses C/C++. Python is beginner-friendly given easier syntax but C speed will appeal to experts.
Learning resources for Pi Pico are quickly catching up too! Raspberry Pi Foundation‘s online book covers building cool projects. Tools like Thonny IDE offer quick code editing.
So getting started on either platform is relatively straightforward. Ultimately acccessible online resources, tons of projects and a helpful community will overcome any coding roadblock!
Verdict: Arduino edges out in beginner-friendliness given larger documentation and pre-built libraries. But Raspberry Pi Pico has momentum given rising Python adoption.
Performance Benchmarks
While specifications reveal some of the story, let us quantify actual performance you can expect:
In standardized Linpack benchmarks that test number crunching ability, Pi Pico scores around 17.5 MFLOPS. Popular Arduino boards manage between 1-4 MFLOPS. That‘s nearly 5X faster mathematical computation!
For common tasks like image processing, Pico can run OpenCV based face detection 4X faster than Arduino Mega 2560 in community tests. Better efficiency benefits computer vision and machine learning use cases.
However, Pi Pico also consumes significantly higher 100 mA peak current. So real world battery longevity may reduce due to faster components. Arduino boards sip just 10-15 mA allowing smaller power sources.
If your application needs local number crunching or intelligence inferencing, the Pi Pico should be seriously considered over slower rivals!
Sample Community Projects
Nothing beats examining real-world implementations. Community projects built on these platforms highlight creative applications across home automation, robotics, wearables and more.
Popular Pi Pico creations:
- Smart Sprinkler system controlled via moisture sensors
- Image recognition based [pet feeder](https://github.com/t COMMENT hodell/pico_box) using OpenCV
- DIY Internet radio with audio output
Cool Arduino community projects:
- Plant health monitoring system using sensors
- Self balancing robot using a gyroscope
- PC Flight Simulator joystick controller
In summary, while Arduino seems geared to simpler sensors and control electronics builds, Pi Pico features more widely in AI based inference and processing centric experiments.
Verdict: Raspberry Pi Pico vs Arduino for DIY Electronics
Hopefully by now, you have a clearer picture of Raspberry Pi Pico and Arduino‘s strengths and target applications!
For those starting out, Arduino Uno continues to offer the simplest, most beginner-friendly entry path into electronics. Consider the extra few dollars as an investment towards tons of online tutorials.
Intermediate makers needing more computing horsepower should certainly evaluate the Raspberry Pi Pico. You expand abilities into computer vision, modern connectivity protocols and local number crunching for under $5!
Advanced users often end up with both platforms to divide up tasks. Arduino handles real world data collection while Pico provides intelligence. Some examples:
- Arduino -> Reading moisture sensors; Pi Pico -> Automatically controlling water valves
- Arduino -> Collecting accelerometer data; Pi Pico -> Running fall detection inference model
At the end of the day, assessing project requirements and personal comfort with coding languages should drive your choice. With over 15+ years of proven solutions, Arduino hosts a mountain of sample projects to kickstart your ambitions. As the Raspberry Pi Pico platform matures, unique applications leveraging its next-gen muscle will surface from its famously creative community.
I hope this guide gives you clarity and confidence to take the next steps with your idea! Building and experimenting beats procrastination every time.
