☀Circuit assembly toys: circuit combinations are familiar with circuits; children can use their imaginations to use motors, switches, battery boxes, LED lights, labyrinth wires, and sensor switches as electronic components to innovate various circuits and up to 125 circuit connections. For example: maze + basketball + sensor + flying saucer + foam car, maze + basketball + sensor + bell + foam car, maze + basketball + sensor + filter disc + dinosaur, maze + basketball + sensor + flying saucer + d

☀Selected examples of combination: dynamic dinosaur + filter disc + foam car + maze. Circuit analysis: The filter disc is connected in parallel with the foam car, as a branch in the main circuit, and then connected in parallel with the dinosaur, and the maze magic wand is used as the switch of the main circuit; when the maze fails to traverse, the main circuit switch is turned on and 3 in the branch Each switch controls each circuit; (in fact, before the magic wand touches the maze line, the fil

☀Significance of circuit teaching: understand electronic components, understand motors, wires, switches, battery boxes and other components. Learn circuit knowledge, through continuous experimentation, learn circuit knowledge intuitively and vividly, which is safe and convenient. Logical thinking, seemingly messy on the surface, will develop a clear logical thinking ability through the guidance of the instructions.

☀Learning purpose: let the connector learn mechanical principles such as fan, crank drive and gearbox. Learn basic circuits and applications such as series and parallel; learn about logic circuits such as NOT gates and AND gates; learn about the relationship between resistance, voltage, current and power through experiments; learn about sound, three primary colors, wind formation, conductivity, Principles such as parabolic motion exercise the ability to capture opportunities. Comes with detailed

☀Warning: The toy needs to be installed with 2 AA batteries. When replacing the batteries, there will be dangers of damage, heat generation, liquid leakage, etc. It must be carried out by adults or parents. Please do not mix used old batteries with new batteries. Mixed use will not only affect the life of the battery, but the old batteries will also have the risk of leakage and damage. Therefore, you should replace them all at one time. When the dry battery power is insufficient, The sound will
