⚡️ Quick Tips and Facts

Before we dive into the soldering iron and code editor, let’s get the lay of the land. At Why Pi™, we’ve seen thousands of students and hobbyists fumble with the Pico, and the ones who succeed usually know these golden rules before they even plug it in.

  • It’s Not a Computer: The Raspberry Pi Pico is a microcontroller, not a microprocessor like the Raspberry Pi 4 or 5. It doesn’t run Linux, it doesn’t have a hard drive, and it doesn’t need an OS to boot. It just does what you tell it to do, instantly.
  • The Magic Chip: At its heart lies the RP2040, a custom silicon chip designed by the Raspberry Pi Foundation. It’s a dual-core ARM Cortex-M0+ processor that punches way above its weight class.
  • Two Languages, One Board: You can program the Pico in MicroPython (great for beginners and rapid protyping) or C/C++ (for maximum performance and control). We’ll cover the differences later, but trust us, you’ll start with Python.
  • Power Flexibility: You can power it via the USB-C port (5V) or the VSYS pin (1.8V to 5.5V). This means you can run it on a simple 9V battery or a LiPo cell without needing a complex regulator.
  • Pico W vs. Pico: The original Pico has no Wi-Fi. The Pico W adds wireless connectivity, which is a game-changer for IoT projects. If you want to control your lights from your phone, grab the W version.

Pro Tip: If you’re coming from an Arduino background, don’t panic. The Pico is faster, has more RAM, and uses a different pinout, but the logic is surprisingly similar.

For a deeper dive into the hardware specs and why the RP2040 is causing such a stir in the maker community, check out our full breakdown of the Raspberry Pi Pico.

📜 From Micro:bit to MicroPython: The Raspberry Pi Pico History

black and silver laptop computer

The story of the Pico isn’t just about a new chip; it’s about a philosophical shift in how we approach embedded systems.

In 2020, the Raspberry Pi Foundation surprised the world. They had been dominating the single-board computer market with the Raspberry Pi, but they wanted to tackle the microcontroller market, which was largely dominated by Arduino and ESP32. The result was the Raspberry Pi Pico, released in January 2020 for a mere $4.

Why did they do it? The founders realized that while the Raspberry Pi was great for media centers and servers, it was overkill for simple tasks like reading a temperature sensor or controlling a motor. They needed something lean, mean, and affordable.

The RP2040 chip was the secret sauce. Unlike the ATmega chips in Arduinos, the RP2040 features:

  • Dual-core processing: Run two tasks simultaneously.
  • 264KB of SRAM: Massive for a microcontroller (Arduinos usually have 2KB).
  • 26 GPIO pins: Plenty of room for expansion.
  • Programmable I/O (PIO): This is the kicker. The PIO allows you to create custom protocols (like driving an LED strip or talking to a specific sensor) without using up the main CPU cycles.

The release of the Pico coincided with the rise of MicroPython, a lightweight version of Python designed for microcontrollers. This made the barrier to entry lower than ever. You didn’t need to understand pointers or memory management to blink an LED anymore.

Did you know? The Pico was so popular that it caused a global shortage of microcontrollers in 2021, leading to a “Pico famine” where makers had to wait months for stock!

🚀 Your First 10 Beginner-Friendly Raspberry Pi Pico Projects


Video: You must try these 3 beginner friendly projects using Raspberry pi pico | Raspberry pi pico projects.








Ready to get your hands dirty? We’ve curated a list of 10 projects that scale in difficulty. Each one teaches a fundamental concept of embedded systems.

1. Blinking an LED: The “Hello World” of Hardware

You can’t build a robot if you can’t make a light blink. This project teaches you the basics of GPIO (General Purpose Input/Output) and timing.

What you’ll learn:

  • How to import the machine and utime libraries in MicroPython.
  • How to set a pin as an output.
  • How toggle a pin state (High/Low).

The Code Snippet:

from machine import Pin
import utime

led = Pin(25, Pin.OUT) # Pin 25 is the onboard LED

while True:
 led.value(1) # Turn LED on
 utime.sleep(1) # Wait 1 second
 led.value(0) # Turn LED off
 utime.sleep(1) # Wait 1 second

Why Pi™ Tip: If you don’t have an external LED, use the onboard one connected to GP25. It’s the easiest way to test your setup.

2. Building a Digital Thermometer with a DHT1 Sensor

Let’s make the Pico “feel” the world. The DHT1 is a classic temperature and humidity sensor. It’s cheap, easy to find, and perfect for beginners.

What you’ll learn:

  • Reading data from a digital sensor.
  • Handling pull-up resistors (the DHT1 needs a 10kΩ resistor between VCC and Data).
  • Parsing sensor data in code.

Step-by-Step:

  1. Connect VCC to 3.3V, GND to GND, and Data to GP15.
  2. Install the dht library in Thony.
  3. Run the code to print temperature and humidity to the shell.

Real-world application: Monitor your houseplants’ environment or check if your server room is overheating.

👉 Shop DHT1 Sensors on:

3. Creating a Simple Motion Detector with a PIR Sensor

Ever wonder how automatic lights work? It’s usually a PIR (Passive Infrared) sensor. This project detects movement by sensing changes infrared radiation.

What you’ll learn:

  • Working with digital inputs.
  • Triggering events based on sensor state.
  • Debouncing (handling false triggers).

The Twist: The PIR sensor can be a bit “jumpy.” We’ll show you how to add a delay in the code so the LED doesn’t flicker wildly when motion is detected.

4. Controlling a Servo Motor for Robotic Arm Basics

Motors are the muscles of robotics. A servo motor moves to a specific angle (0 to 180 degrees) based on a signal.

What you’ll learn:

  • PWM (Pulse Width Modulation): How to control the width of a signal to dictate position.
  • Power management: Servos can draw a lot of current; learn why you might need an external power source.
  • Mapping values: Converting a slider input to angle.

Project Idea: Build a simple robotic arm that picks up a cup.

5. Making a Mini Weather Station with BME280

Upgrade from the DHT1 to the BME280. This sensor measures temperature, humidity, and barometric pressure. It uses the I2C protocol, which is faster and uses fewer pins.

What you’ll learn:

  • I2C communication: Understanding SDA and SCL lines.
  • Reading multiple data points from one sensor.
  • Calculating altitude based on pressure.

Why Pi™ Insight: The BME280 is more accurate than the DHT1 but requires a bit more wiring. It’s a great step up in complexity!

6. Designing a Custom Keypad Lock System

Security is fun. Let’s build a keypad that unlocks a “door” (an LED or a servo) only when the correct code is entered.

What you’ll learn:

  • Matrix scanning: How to read a 4×4 keypad efficiently.
  • Storing and comparing strings in MicroPython.
  • Basic logic flow (If/Else statements).

The Challenge: What happens if someone enters the wrong code three times? Add a “lockout” timer to your code!

7. Building a Retro Handheld Game Console

Who says microcontrollers can’t play games? Using a small OLED screen and a few buttons, you can build a Pong or Snake game console.

What you’ll learn:

  • Driving OLED displays (SSD1306).
  • Handling button inputs for game controls.
  • Game loops and frame rates.

Recommended Display:

8. Automating a Plant Watering System

Keep your plants alive while you’re on vacation. This project uses a soil moisture sensor to detect when the soil is dry and triggers a water pump.

What you’ll learn:

  • Analog inputs: Reading variable resistance from the soil sensor.
  • Controlling high-power devices (pumps) with a relay module.
  • Setting thresholds for automation.

Safety Note: Never connect mains water pumps directly to the Pico. Always use a relay to isolate the high voltage.

9. Creating a Smart LED Strip Controller

Lighting is everything. Control a strip of WS2812B (NeoPixel) LEDs to create dynamic lighting effects.

What you’ll learn:

  • Addressable LEDs: Controlling individual pixels.
  • Color mixing (RGB values).
  • Creating animations (rainbows, fades, strobes).

Why Pi™ Tip: WS2812B strips can draw a lot of power. If you have more than 30 LEDs, you must use an external 5V power supply.

👉 Shop LED Strips on:

10. Setting Up a Basic Home Security Alarm

Combine everything you’ve learned: a PIR sensor, a buzer, and an LED. When motion is detected, the alarm sounds and the light flashes.

What you’ll learn:

  • State machines: Managing different states (Armed, Disarmed, Alarm).
  • Integrating multiple sensors.
  • Adding a “siren” sound with a buzzer.

The Final Challenge: Can you add a delay so the alarm doesn’t go off immediately when you walk in the door?

🧠 Mastering MicroPython vs. C++: Which Language Should You Choose?


Video: Top 5 Beginner Raspberry Pi Projects: A Beginner’s Guide to Getting Started with Raspberry Pi.








This is the million-dollar question for every new Pico owner. The Pico supports both MicroPython and C/C++. Which one is right for you?

MicroPython: The Speed Demon

  • Pros:
    Rapid Protyping: Write code, save, and run instantly. No compiling needed.
    Readable: Python syntax is intuitive and easy to learn.
    Interactive: You can type commands directly into the REPL (Read-Eval-Print Loop) in Thony.
  • Cons:
    Slower: Interpreted code runs slower than compiled code.
    Memory Heavy: Uses more RAM, which might be an issue for complex projects.

C/C++: The Performance King

  • Pros:
    Speed: Compiled code runs at the full speed of the RP2040.
    Efficiency: Uses less memory, allowing for more complex logic.
    Control: Direct access to hardware registers and the PIO state machines.
  • Cons:
    Step Learning Curve: Requires understanding of pointers, memory management, and compilation.
    Slower Workflow: You must compile and flash the code every time you make a change.

The Verdict:
If you are a beginer, start with MicroPython. It lets you focus on the logic and the fun of building without getting boged down in syntax errors. Once you hit the limits of MicroPython (speed or memory), or if you need to use the PIO for custom protocols, then graduate to C/C++.

Why Pi™ Anecdote: We had a student try to build a high-speed data logger in MicroPython. It worked, but the data was too slow. Switching to C++ doubled the sampling rate instantly. But for 95% of projects, MicroPython is plenty fast!

🔌 Understanding GPIO Pins and Circuit Connections


Video: 3 Easy @raspberrypi Pico Projects that ANYONE can tackle!








The GPIO (General Purpose Input/Output) pins are your gateway to the physical world. The Pico has 26 GPIO pins, but they aren’t all created equal.

Pinout Basics

  • Digital I/O: Most pins can act as inputs or outputs.
  • Analog Inputs: Pins GP26, GP27, and GP28 have built-in ADCs (Analog-to-Digital Converters). You can read variable voltages (like from a potentiometer) on these pins.
  • PWM: Almost any pin can generate PWM signals, useful for diming LEDs or controlling servos.
  • Special Functions: Some pins are reserved for I2C, SPI, and UART communication.

The Golden Rules of Wiring

  1. Common Ground: Always connect the GND of your Pico to the GND of your sensor or motor. Without a common ground, nothing will work.
  2. Voltage Levels: The Pico runs at 3.3V logic. Do not connect 5V signals directly to a GPIO pin; you might fry the chip. Use a voltage divider or a logic level shifter if your sensor is 5V.
  3. Current Limits: Each GPIO pin can source/sink about 12mA. If you need more (like for an LED strip), use a transistor or a driver circuit.

Visual Guide:

Pin Type Function Example Use
GPIO Digital Input/Output Button, LED
ADC Analog Input Potentiometer, Soil Sensor
I2C Serial Communication OLED, BME280
SPI High-Speed Serial SD Card, Display
UART Serial Communication GPS Module, Bluetooth
