Ungayenza kanjani i-speedometer yakho yebhayisikili nge-Arduino

Namuhla, ngekhulu lama-XNUMX, cishe noma iyiphi imoto iza nejubane layo kanye ne-odometer. Ngakho-ke kuzimoto, izithuthuthu, amanye ama-e-Bikes, njll. Ngaphezu kwalokho, kunezinhlelo zokusebenza eziningi ku-App Store ezosivumela ukuthi sazi ukuthi sishesha kangakanani nokuthi senza amakhilomitha amangaki sisebenzisa i-GPS yedivayisi yeselula. Kepha yini inkinga ngalezi zicelo? Ukugijimela kudivayisi engeyona eshibhe njalo. Njengakucishe konke, isixazululo senkinga kungaba dala umshini wokubonisa izinga lejubane lethu.

Wonke umuntu uyazi ukuthi kubiza ini i-iPhone. Ngokwami, nginenye futhi izinyanga bengisaba ukuwa ebhayisikili lami, kakhulu ngenxa yocingo lwami kunami. Manje ngihamba neGarmin, kepha noma iyiphi idivayisi yalo mkhiqizo inenani lamakhulu ama-euro, okuthile abasebenzisi abaningi abakwazi noma abafuna ukukusebenzisa. Uma sazi esikwenzayo, kwesinye isikhathi inketho engcono kakhulu ukuthi sihlanganise i-hardware yethu futhi kule ndatshana sizokukhombisa ukuthi kanjani ukwakha kusuka ekuqaleni i-odometer yethu.

I-Speedometer ne-odometer yamabhayisikili

Izidingo

Ukufaka i-speedometer yethu sizodinga:

• Arduino UNO & Okuqotho 1 (Ayikho imikhiqizo etholakele.).
• 1 I-Adafruit RGB Blacklight LCD - 16 × 2 (Thenga).
• 2 SparkFun 12mm Pushbutton Ishintsha Thenga.
• Isivikeli esingu-1 221 ohm (Thenga).
• Ama-3 10k ohm resistors (Thenga).
• 1 10k ohm ithuba elilodwa lokujika (Thenga).
• 1 Inzwa yomphumela weHholo (Thenga).
• Izandla, isikhathi nokubekezela.

Lesi sifundo sikabani?

Njengoba sishilo ngaphambili, namuhla cishe noma iyiphi ifoni emakethe ine-GPS futhi inohlelo lokusebenza olutholakala njenge Runtastic noma iStrava. Ngokwami, angizange ngincome lesi sifundo kunoma ngubani osenayo i-smartphone, ngaphandle kwalapho ufuna ukuzakhela i-speedometer ngokwakho. Yebo, lokho nokuqiniseka ukuthi awuyiphuli ifoni yakho engozini.

Kungabhekiswa nakulabo asebevele benayo i-Arduino Starter Kit ngesinye isizathu futhi abafuni ukwenza imfoloko ukuthi yini ikhompyutha yomjikelezo eyisisekelo. Le-speedometer izoba nenani eliphelele elingaphezu nje kuka- € 30, ngakho-ke umgomo yalesi sifundo kufanele ibe kubantu abangafuni ukuchitha imali eningi futhi abafuna ukwenziwa i-akhawunti yekhilomitha ngezandla zabo.

Sizokwakha ini

Esizokukhiqiza yi-odometer nesivinini sejubane samabhayisikili azositshela:

• Ukuhamba ibanga ngamakhilomitha.
• Isikhathi somsebenzi ngamahora, imizuzu namasekhondi.
• Ijubane elimaphakathi ku-km / h.
• Isivinini esikhulu sifinyelelwe.
• Amandla okurekhoda kuze kufike emathangeni angama-99.

Ungayisebenzisa kanjani le-speedometer efakwe ngokugcwele

Lapho sesiqedile ukukhiqiza umshini wokubonisa izinga lejubane lethu lamabhayisikili singakwazi ukukuvula. I- okokuqala siyiqala noma senza a Setha kabusha Umlayezo onombhalo othi “PRESS BUTTON TO Start” uzovela esikrinini se-16 × 2 LCD. Ukucindezela eyodwa yezinkinobho zokumisa isikhashana / ukuqhubeka kabusha noma imodi yokubonisa kuzoqala isikhathi / ithanga lokuqala.

Okulandelayo esizokubona umlayezo othi "CYCLE SAFELY!" (sakaza ngokucophelela) amasekhondi ama-2, kepha kuleso sikhathi sesikhathi iyarekhoda. Lapho umyalezo unyamalala sizokwazi ukubona amakhilomitha ahanjiwe, isivinini esiseduze ne- "S" (se- "Speed"), isikhathi esivele sidliwe kulayini wesibili kanye nesilinganiso esiseduze ne- "A" (se- "A average ").

Yonke imininingwane iboniswa ku isikhathi sangempela. Lokhu kubalulekile uma sibheka ukuthi izinhlelo zokusebenza zeselula engizishilo ngenhla zibala ibanga ne-GPS, ngakho-ke ayiboniswa ngesikhathi sangempela. Umehluko ukuthi, uma singenayo inzwa esondweni, kumaselula siyabona ukuthi ijubane liyagxuma, ngenkathi kule divayisi sizobona ukuthi amanani aguquka kancane kancane njengasemotweni. Izinzwa ezishiwo kufanele zibe yi-bluetooth futhi zihambisane nedivayisi yeselula. Futhi ukuzithenga ngokuhlukile ngokuvamile akubizi kakhulu.

Ibonisa imininingwane emakhoneni ayo amane

Uphawu "+" luzovela phezulu ngakwesobunxele ngama-250ms lapho ithola ukuguqulwa okulodwa kwesondo. Ukucindezela inkinobho yemodi yokubonisa kuzoshintsha i- «A» yomugqa wesibili uye ku- «M», okuzosikhombisa i- isivinini esiphezulu esikuzuzile kuze kube manje kuleso sikhathi / isikhathi.

Ngokucindezela inkinobho Misa isikhashana / Qalisa kabusha kuzoyeka ukurekhoda futhi izogcina ithanga lamanje kwimemori. Umlayezo othi "MISA kancane!" Uzovela lapho. imizuzwana emi-2 kanye nemiphumela yethanga esisanda kuliqeda izovela nenombolo yethanga ngaphezulu kwesobunxele kwesikrini, kulandelwe u- "Avg" okukhombisa isivinini esimaphakathi sethanga lonke kanye no- "Max" ngejubane eliphezulu lohambo . Kulayini wesibili sizobona ibanga ngamakhilomitha lilandelwe ithanga ngamahora, imizuzu namasekhondi.

Iyakwazi ukonga kuze kufike emathangeni angama-99

Uma sicindezela inkinobho yemodi yokubonisa ngenkathi imisiwe izohamba ukushintsha phakathi kwamathanga ahlukene aqoshiwe. Isikhathi sokuqala lapho sicindezela khona, sizosikhombisa ithanga elihle kunabo bonke nge- "T" ngaphezulu kwesobunxele, kanti eminye imishini izosiyisa emathangeni oku-1, 2, 3, njll. .

Uma sicindezela inkinobho yokumisa okwesikhashana futhi, izorekhoda futhi, kodwa ithanga elisha, iphinde ibonise umlayezo osicela ukuthi sijikeleze ngokucophelela. Uma sicindezela inkinobho yokumisa isikhashana futhi ngenkathi sibona umlayezo othi "CYCLE SAFELY!" akunamathanga azorekhodwa futhi idivayisi izobuyela kumodi yokumisa isikhashana ekhombisa idatha yethanga lokugcina esilenzile.

Le umshini wokubonisa izinga lejubane Ungarekhoda amathanga angama-99. Uma sifika emlenzeni we-100, imininingwane esele izogcinwa phezu kwephothi 99. Okungeke kuguquke ukuthi amarekhodi atholakele ngesikhathi somsebenzi wethu azogcinwa noma ngabe idatha esesigabeni 99 isuliwe. Ngamanye amagama, uma ethangeni 99 sifeza irekhodi lethu futhi senza ibanga le-100, kuzosulwa kuphela ijubane elijwayelekile nedatha yebanga le-lap 99, kepha isivinini esiphezulu sizosala.

Kule vidiyo elandelayo ungabona ukuthi le-speedometer yamabhayisikili isebenza kanjani. I- ikhodi yesoftware ungayilanda ngokuchofoza LONTO futhi ungalanda uhlelo ngokuchofoza kwesokudla bese ugcine isithombe kusuka kusiphequluli sakho.

Ulwazi oluningi.
