## Description

Kit for building a 4WD robot car controllable via Bluetooth or IR remote control, suitable for Arduino projects. Includes chassis with 4 motors and wheels, L298N driver and UNO compatible board, plus sensors for obstacle avoidance with HC-SR04 and line tracking with IR modules, providing the basis for manual control or autonomous operation.
Intelligent 4WD robot kit, controllable via Bluetooth or IR, obstacle avoidance and line following functions.
For assembly instructions and example code access the link: Smart Car Tutorial
Attention: There are many codes with different configurations available online as "open source". This is not a "standard" kit with step-by-step instructions. The instructions in the files provided on the site may have component differences (for example, the kit does not include an LCD1602 screen) or may require compiling different code.
WE DO NOT RECOMMEND THIS PRODUCT TO PERSONS WHO HAVE NOT WORKED WITH THE COMPONENTS IN THE KIT BEFORE AND WHO DO NOT HAVE EXPERIENCE IN PROGRAMMING AND USING THE UNO R3 BOARD! THIS IS NOT A KIT WITH STEP-BY-STEP INSTRUCTIONS. THIS PRODUCT IS A COLLECTION OF COMPONENTS NECESSARY FOR ASSEMBLING THE ROBOT. IF YOU ARE NOT SURE, PLEASE DO NOT PURCHASE THIS KIT!
With the components in the kit, you can build a car controllable via Bluetooth or IR remote control. The components also allow you to create a fully autonomous car that can avoid obstacles or follow a line.
For beginners, we recommend approaching the project progressively, starting with simple motor control via Bluetooth with Arduino and an H bridge. Example here (even though the H bridge in the tutorials is different, the pins are the same).
