Overview
A 4 digit display module usually uses 12 pins. In this Grove gadget the TM1637 is used to scale down the control pins into two Grove pins. This way It only takes two digital pins from an Arduino to control the content on the display, this even includes the luminance of the display. For projects that require a alpha-numeric display, this is a great choice.
Features:
- 4 digit red alpha-numeric display
- Grove compatible
- 8 adjustable luminance levels

A simple BlueTooth (BLE) remote controller for the Arduino Alvik robot, implemented in MicroPyhton

We’re thrilled to announce that Arduino Education has been shortlisted for the Bett Awards 2025, this time in the AV, VR/AR, Robotics, or Digital Device category with our Alvik robot! This recognition highlights our dedication to innovation, inclusivity, and the advancement of practical STEM education. The Bett Awards celebrate leading-edge technology in education, with entries evaluated on key criteria such as innovation, curriculum suitability, online safety, research evidence, customer support and more. About the Alvik robot Alvik is an adaptable, lifelong learning robot that supports educators and students as they transition from block-based programming to text-based coding using MicroPython and Arduino language. It enables them to explore robotics and tackle real-life challenges with comprehensive learning content. However, Alvik isn’t just designed to teach programming and robotics; it can also enhance students’ understanding of topics like mathematics and astronomy, along with other engaging projects. Alvik’s curriculum-aligned course makes it an ideal fit for today’s classrooms, empowering students with hands-on skills and a strong foundation in STEAM. But what truly sets Alvik apart from other educational robots is its limitless potential for customization. Students and teachers can easily add external sensors using the I2C Grove and Qwiic plug-and-play connectors, eliminating the need for soldering or complex wiring. Additionally, the LEGO® Technic™ and M3 screw connectors encourage hands-on creativity, allowing users to build custom components and further expand Alvik’s capabilities. We’re honored to be recognized once again, and we can’t wait to attend Bett in just a couple of months. The winners will be announced at the Bett Awards 2025 Ceremony on January 22nd at The Brewery, London. We look forward to seeing you there!
