About This

• 【Smart sensor circuits for kids】 Build real reacting projects with three sensors: a flashlight-activated lamp that turns on when light hits the sensor (light sensor keeps the circuit closed under illumination), a tilt-to-start color fan (gravity sensor), and a pressure-activated buzzer alarm (pressure sensor). The cartoon step-by-step manual guides kids through each build and extends to simple AND/OR logic challenges.
• 【150+ guided builds (168 total) + cartoon manual】 Kid-friendly, full-color instructions start with safety and parts ID, then progress from basic series/parallel to logic gates (AND/OR/NOT). Ideal educational science kit for ages 6–12 at home, homeschool, or classroom.
• 【Snap-together, no soldering】 37 durable parts snap onto dual base grids for bigger layouts and teamwork: motor & color fan, buzzer, resistors, toggle & press switches, two 3-way switches, gravity/light/pressure sensors, fiber-optic tree and street light.
• 【For home and classroom】 Low-voltage design, clear visuals, and quick setup make this a great circuit board for kids and kids circuit board building kit. Supports collaborative builds, showcases cause-and-effect, and strengthens problem-solving and presentation skills for ages 6–12.
• 【Real growth: creativity, logic & confidence】 More than a toy—kids plan, test, and iterate like mini engineers, building logical thinking, perseverance, and confidence. A thoughtful STEM toy gift for curious learners. Requires 3× AA batteries (not included).
