## Description

DIY kit for making a mini radar with ultrasonic obstacle detection, based on UNO R3 compatible board. Includes HC-SR04 sensor and SG90 servo motor for scanning, 1.8 inch color TFT display with real-time graphics, easy integration into Arduino IDE, ideal for educational projects and distance measurement experiments.
This mini radar kit is ideal for electronics and robotics enthusiasts who want to build a functional ultrasonic obstacle detection system. The unassembled kit allows for the creation of a mini radar with an HC SR04 ultrasonic sensor and a 1.8 inch TFT color display, providing a hands-on experience for those interested in measuring distances and programming an Arduino Uno R3 compatible board.
It includes features such as real-time graphical display, control via Arduino IDE, and a compact design suitable for educational projects or technical experiments.
The product requires experience, as it does not include step-by-step instructions and is intended for users familiar with programming and assembling electronic components.
WE DO NOT RECOMMEND THIS PRODUCT TO PEOPLE WHO HAVE NO EXPERIENCE IN USING THE UNO R3 BOARD AND PROGRAMMING IN THE ARDUINO IDE. THIS IS A KIT MADE UP OF COMPONENTS ONLY. IF YOU DO NOT HAVE THE NECESSARY EXPERIENCE, PLEASE DO NOT BUY THE KIT.
Specifications:
Supply voltage: 5-12V DC
Microcontroller used: Uno R3
Sensor: Ultrasonic HC-SR04
Screen: 1.8-inch TFT RGB
Resolution: 128x160 pixels
Display driver: ILI9341
Servo motor: SG90 180 degrees
