The pipe circuit

This product is for children to better understand the knowledge of the circuit, when the circuit is convenient and fast. Modular design of circuit components, using the effect of lighting to highlight the current flow of the circuit, more intuitive understanding of the circuit principle. Every time a module is spliced, the module will light up to indicate normal connectivity, so as to remind in real time. It solves the limitation of learning circuit knowledge, such as site, tools and instruments, and brings users a low threshold of product experience.
