![]() A project where a simple circuit was introduced that could pick up sound, which then sets off a LED. The concept looks deeper into simply placing a circuit into a box. For instance, why would you need something that detects sound in the first place? So, this object not only gives the owner a visible sign that the plant is fine - with the blinking light imitating a heartbeat. Talking to the plant also sets it off - giving the plant a personality, as if it is excited to hear you speak. |
