Build a touchscreen-controlled LEGO Spike Prime robot that responds in real time! In this step-by-step tutorial, I show you how to use LVGL and MicroPython on MicroBlocks to create a smart dashboard for your LEGO robot. You’ll learn how to control motors, read gyro data, and design a live UI—all from a touchscreen.
We’ll flash firmware, install libraries, build an interface with buttons and sliders, and connect it to Pybricks on the Spike Prime hub for full control. Perfect for anyone who wants to take their LEGO robotics projects beyond the basics.
🔧 What You’ll Learn
- Flash MicroBlocks firmware
- Install and use LVGL for UI design
- Add sliders, buttons, and live data charts
- Stream gyro sensor data to the screen
- Control motors and parameters in real time
- Communicate between MicroBlocks and LEGO Spike Prime via MicroPUP
