Move up Delete Move down

Outcome

Light up the led light by using different buttons and building different circuits.

Move up Delete Move down

Process

The most challenging part in this exercise was the wiring. Putting the resistor in the correct place in the breadboard and connecting the jump wires precisely is always a challenging task.

Reflection

I would try create/propose a new circuit so that way I totally understand the logic behing specific connections and not just do it by the instructions. This will allow me to explore and be more creative for my final projet.
