Arduino with Tinkercad Level 2: Robotics and Smart Systems Grade 4-7

This Level 2 Arduino course uses the Tinkercad Circuits simulator to take young makers deeper into robotics and smart systems. Over eight hands-on lessons, students program Arduino sketches, connect and read sensors, control motors and servos, and apply basic 3D modeling ideas to robot designs. Lessons focus on real components in the simulator: ultrasonic and IR sensors, temperature/humidity sensors, LEDs, buzzers, motor drivers and servos. Project work includes smart traffic lights with pedestrian control, obstacle-avoiding and line-following robot simulations, a motion-activated security alarm, a simulated smart parking gate, and a mini weather station that displays readings. Instruction emphasizes practical coding patterns, sensor integration, and applying simple automation logic to solve problems. Students get instant feedback in the Tinkercad simulator, iterate on designs, and present their final robot or smart system. The course is suitable for students in grades 4 to 7 who want to build simulated electronics and robotics projects without physical hardware.
