Arduino Starter Kit R4

The Arduino Starter Kit R4 brings together everything you need to start your maker journey or level up a classroom, no prior experience required. At its core is the UNO R4 WiFi board, giving you stronger performance, built-in wireless connectivity, and full compatibility with the wider Arduino ecosystem.

Inside the box is a printed project book (in English) covering 13 guided, hands-on builds, along with every component needed to complete them, plus access to a growing online project library. Once you register your kit at courses.arduino.cc/starter-kit-r4, you'll unlock translated content in French, Italian, Spanish, German, and Portuguese, along with new projects added regularly by the Arduino team. A voucher for the Arduino Fundamentals certification exam is also included, so you can put an official stamp on what you've learned.

Key benefits

• Ready for modern making – the UNO R4 WiFi board delivers stronger performance plus built-in Wi-Fi and Bluetooth for connected projects from day one
• No barriers to coding – the Arduino GenAI coding assistant is built into the online editor to help debug, explain, and extend your code
• Learn by building – work through real projects covering sensors, motors, displays, and logic
• A growing platform – translated content and new original projects are added over time
• Designed for classrooms – clear, step-by-step guidance suits group and individual STEM learning
• From beginner to certified – complete the book, then sit the official Arduino Fundamentals exam using the included voucher (one attempt)

What you can build

Explore how everyday objects go digital: build an interactive lamp that responds to touch, a musical instrument you play by waving your hand, and more. In a classroom setting it's a great way to get students collaborating, iterating, and inventing together. Each project builds core skills that carry forward to more advanced Arduino boards and bigger projects down the line.

What's included

• Learning content – printed project booklet plus access to the expanding online library (registration required)
• Visual feedback – 16x2 character LCD, LED matrix on the UNO R4, and a wide range of individual LEDs
• Environmental sensing – 4 phototransistors, a temperature sensor, and a tilt sensor
• Actuation and movement – a small DC motor and a micro servo
• Other inputs and feedback – pushbuttons, potentiometers, and a piezo buzzer
• All the essentials – cables, breadboard, and mounting base to get building straight away

Full parts list

Powered by the Arduino UNO R4 WiFi

Strong processing power and a wide feature set make the UNO R4 WiFi the perfect match for the parts included in this kit. Once you've worked through the book, the kit can be expanded further with Modulino devices, and the R4's onboard peripherals leave plenty of room to grow into your own projects, browse Arduino Project Hub for inspiration.

Learn faster with the Arduino AI Assistant

Built directly into the online editor, the AI Assistant helps debug code, add new features, and explain concepts as you go. Read more on the Arduino blog.
