Project Scenarios: Matching the Right Board to the Right Job
For remote sensors, door monitors, or garden moisture probes, Arduino excels with ultra-low sleep currents and instant wake. Months-long battery life, quick interrupts, and deterministic timing keep data reliable without frequent charging or complicated power management.
Project Scenarios: Matching the Right Board to the Right Job
If your project needs a camera, a dashboard, or Python-driven analytics, Raspberry Pi shines. Run Flask or Node-RED, store data locally, use HDMI displays, and add watchdogs to keep headless services resilient during unexpected network hiccups.
Compute and memory headroom
Raspberry Pi packs multicore CPUs, ample RAM, and GPU support, handling Python, containers, and even lightweight databases. Arduino offers tight, efficient C/C++ on microcontrollers, perfect for fast I/O tasks without operating system overhead.
Power budget and heat
Arduino boards can sip power—often well under a watt and far lower in sleep—making coin cells or small LiPo packs viable. Raspberry Pi commonly draws multiple watts, benefits from stable supplies, and may require heat dissipation under sustained loads.
Pins, protocols, and timing
Arduino exposes GPIO with precise timing, PWM, interrupts, and reliable hardware serial, I2C, and SPI. Raspberry Pi offers abundant interfaces too, but Linux scheduling can introduce jitter that complicates tight control loops and strict timing.
Programming Experience and Tools
Arduino favors C/C++ with the Arduino IDE or PlatformIO, giving tight binaries and real-time behavior. Raspberry Pi invites Python, JavaScript, or C/C++ on Linux, enabling quick scripting, rich libraries, and familiar desktop-like workflows for many developers.
Programming Experience and Tools
Both ecosystems are famously well-documented. Arduino libraries simplify sensors, servos, and low-power modes. Raspberry Pi repositories provide camera pipelines, web stacks, and AI toolkits. Verify maintenance status, read issues, and star trustworthy repos before adopting.

A Reusable Decision Framework
Does your project need an operating system or GUI? Is precise real-time control essential? What is your power budget and battery plan? Your answers usually point decisively to Arduino or Raspberry Pi.
A Reusable Decision Framework
Prototype the riskiest feature first. Try a minimal Arduino sensor loop or a Raspberry Pi camera-stream. Measure power, latency, and stability. Share results, and we will help interpret numbers and refine your next sprint.
