Circuit da Code - Aiki Tare

• Da zarar an ƙirƙiri da'ira kuma aka haɓaka lambar, tsarin zai fara aiki tare. Wannan ya haɗa da samun accelerometer auna manyan canje-canje (saboda faɗuwa). Idan na'urar accelerometer ta gano babban canji, to, allon taɓawa yana cewa "Shin Kuna Lafiya" kuma yana ba da maɓalli don mai amfani ya danna.

Shigar mai amfani

• Idan mai amfani ya danna maɓallin, to, allon ya zama kore, kuma ya ce "Ee," don haka tsarin ya san mai amfani yana da lafiya. Idan mai amfani bai danna maɓallin ba, yana nuna cewa za'a iya samun faɗuwa, to piezospeaker yana yin sauti.

Ƙarin Ra'ayoyi

• Don tsawaita iyawar rayuwar Arduino, muna ba da shawarar ƙara ƙirar bluetooth a madadin piezospeaker. Idan kun yi haka, kuna iya canza lambar ta yadda idan wanda ya faɗi bai amsa tambayar da aka yi masa ba, ana aika faɗakarwa ta na'urar ta bluetooth zuwa ga wanda ya keɓe, wanda zai iya zuwa ya duba su.
