Session 2 Interactive Review

Session 2 of 8. The components that make up a circuit — resistors, capacitors, LEDs and buttons — plus the microcontroller that controls them, and a first working breadboard build.

Session 1 explained how current behaves. This session introduces the components that shape it —
resistors, capacitors, LEDs and buttons — and the microcontroller that sits at the centre of your
Pathfinder deciding what happens.
