This set-up is designed as a circuit-board, and it is easy to operate and convenient for the students to understand the circuit connection. Compared with the wire circuit, it may reduce the possibility of causing disorder. Due to a completeness of components, it may help us finish the experiment on circuit connection and gate circuit in Senior School.
