6. Circuit on Plug-board

7. Summary ● Any circuit MUST make a complete closed loop – current flow ● A switch works by breaking the closed loop ● Plug-Boards are a useful way of creating a circuit without committing to it. ● By soldering the wires together the circuit could be made into a real buzzer for use with kids etc.

8. Next Sessions ● Beginner Soldering Techniques – Learn how to make the circuit into a complete system ● Introduction to Electronics part 2 – Learn about some of the other components to make more complex circuits ● See notice board for dates and to put your name down.
