Mayelana nalolu hlelo lokusebenza

Ngemva kokufaka imojula ye-Wi-Fi ebhodini le-Arduino, ukusebenzisa lolu hlelo lokusebenza kumakhalekhukhwini ukuxhuma ukuxhumana kwe-Wi-Fi phakathi kwefoni ephathekayo ne-Arduino, ucindezela izinkinobho ezingu-10 ezinikezwe kumakhalekhukhwini ukuze ubone ukucindezelwa kwenkinobho i-Arduino ukwenza umsebenzi oyifunayo. uhlelo lokusebenza oluvumelayo
- Inkinobho eyodwa: 10

(Idatha ithunyelwe ku-Arduino lapho inkinobho ngayinye icindezelwa)
Inkinobho 1: ‘0’ (hexadecimal 30) Inkinobho 2: ‘1’ (hexadecimal 31)
Inkinobho 3: ‘2’ (hexadecimal 32) Inkinobho 4: ‘3’ (hexadecimal 33)
Inkinobho 5: ‘4’ (hexadecimal 34) Inkinobho 6: ‘5’ (hexadecimal 35)
Inkinobho 7: ‘6’ (hexadecimal 36) Inkinobho 8: ‘7’ (hexadecimal 37)
Inkinobho 9: ‘8’ (hexadecimal 38) Inkinobho 10: ‘9’ (hexadecimal 39)

(Isibonelo sohlelo ku-Arduino)
I-LED exhunywe kumbobo yedijithali engu-5 ye-Arduino ivula uma inkinobho 1 icindezelwa kanye, futhi iyacisha uma icindezelwa futhi. (Guqula isenzo)
