T-M274 Radar DIY Learning Kit

Overview

The T-M274 Radar DIY Learning Kit is a hands-on educational project that teaches the fundamentals of radar technology, ultrasonic sensing, and distance measurement. Learners assemble an Arduino-compatible radar system that scans 0 to 180 degrees using a servo-mounted ultrasonic sensor and visualizes detected object position and distance in real time. This kit is ideal for classroom STEM activities, maker workshops, and hobbyist experimentation.
