Course need to implement hardware function, but dogs have no contact with pure design, only self-study, solid in the cellar, thank you
Simple structure, as shown in the figure after successful insert two parts, namely complete electricity trigger condition, part two bulbs glow inside, at the same time there will be a voice broadcast
Question: after insert (i.e., electricity) voice broadcast, how to realize the trouble as simple as possible, or what arduino can realize the function name (attached tutorial links is better,,), thank you
