Kauj Ruam 4: Sib dhos lub voos xwmfab

Rau txhua qhov ntsiab lus ntawm kev sib dhos lub voos xwmfab koj yuav tsum xa mus rau cov vis dis aus saum toj no.

Sib dhos lub voos xwmfab tsis yog qhov yooj yim tshaj plaws, tab sis kom ua kom yooj yim dua me ntsis Kuv tau tsim cov kev pab me me uas tsawg kawg peb ntawm rau rau PCBs tuaj yeem ua ke ua ke. Ua ob zaug koj yuav tau txais ob sab PCB uas yuav tsum tau txuas nrog thaum txhua yam ua haujlwm. Yog, xyuas kom txhua yam ua tiav. Kuv tsis tau sim nws txog tam sim no, tab sis kev tshem tawm ib qho PCB tawm ntawm lub voos xwmfab tuaj yeem nyuaj.

Nco ntsoov muab tshuaj txhuam peb PCBs ua ke ua ntej koj txuas lub roj teeb. Txwv tsis pub koj yuav tsum hloov kho cov ntaub ntawv.stl nrog lub qhov me me qhov twg lub jack haum rau hauv.

Kauj ruam 5: Arduino Code

Lub voos xwmfab yuav pib nrog WiFi xiam oob khab kom txuag tau qee lub zog, uas yog hu ua modem pw tsaug zog. Hais txog ESPs cov ntaub ntawv, MCU siv sijhawm tsuas yog 15mA thaum nyob hauv modem pw, qhov nws xav tau ib puag ncig 70mA hauv ib txwm muaj. Zoo rau cov khoom siv roj teeb zoo li qhov no. Txhawm rau ua tiav qhov no koj yuav xav tau cov lej hauv qab no ua ntej hu rau teeb tsa ua haujlwm.

void preinit () {

ESP8266WiFiClass:: preinitWiFiOff (); }

Nrog lwm lub pob nyem koj tuaj yeem tsim WiFi los ntawm kev hu rau tus qauv WiFi.begin () ua haujlwm lossis hauv qhov no Blynk.begin () uas yog teeb tsa hu rau APP uas kuv tau xaiv los tswj lub voos xwmfab.

Hloov qee qhov kev ua yeeb yaj kiab rau lub voos xwmfab tsuas yog ua lej me ntsis. Kev hloov pauv ntawm matrix mus rau pixel ntawm ib lub phab ntsa tshwj xeeb tau ua tiav nrog cov haujlwm pabcuam yooj yim no:

int tau_pixel (int mat, int px, int py) {

// pib ntawm kaum sab laug rov qab (px + py * 3) + mat * 9; }

Xa mus rau PCB pixel kev txheeb xyuas hauv kauj ruam 2, thawj lub zeem muag yog ib qho saum toj kawg nkaus, qhov thib ob yog lub ntsej muag tig mus rau ib sab, cov tom ntej yog nyob ib ncig ntawm lub voos xwmfab mus rau hauv txoj kev yog thiab lub cim kawg yog hauv qab.

Thaum siv cov lej txuas, koj yuav tsum hloov kho WiFi daim ntawv pov thawj kom phim koj lub network. Txhawm rau siv kom raug nrog Blynk APP, nco ntsoov muab ob daim ntawv (BLYNK.ino thiab lwm qhov nrog Blynk hauv nws) rau hauv tib daim nplaub tshev ua ntej qhib daim duab. Cov duab kos muaj ob lub tab sib txawv. Lwm cov ntawv, uas ua tsis muaj dab tsi, tsis tas yuav tsum tau nruab nrog lwm lub tab. Nws tsuas yog ua rau lub voos xwmfab tsaug zog thaum lub pob tsis tau nias. Txwv tsis pub lub voos xwmfab yuav tsis tsaug zog thiab yuav kos tam sim no txhua lub sijhawm.

Kauj ruam 6: APP

Raws li twb tau hais lawm, lub voos xwmfab pib nrog nias lub pob ib zaug. Tab sis nws yuav tsis pib nrog WiFi ua haujlwm txhua. Lwm qhov xovxwm ib zaug thaum lub voos xwmfab twb tau pib yuav pib WiFi thiab txuas rau lub network uas tau npaj ua ntej. Tom qab koj tuaj yeem siv BlynkAPP los tswj lub voos xwmfab. Tau kawg koj tuaj yeem txuas ntxiv kev ua haujlwm, muaj ntau txoj hauv kev rau qhov no …

Ib qho piv txwv yooj yim teeb tsa hauv Blynk APP tau qhia ntawm no. Nws suav nrog ob qho SLIDER (ci ntsa iab thiab ua kom nrawm), ob lub STYLED BUTTON (hloov cov qauv duab thiab hloov lub voos xwmfab tawm), ib kauj ruam rau kev hloov pauv lub voos xwmfab, ib qho LED rau pom uas cov dice sab tau nce thiab kawg tab sis tsis tsawg kawg GAUGE rau qhia lub roj teeb xwm txheej. Txhua yam ntawm cov cuab yeej no siv cov pins virtual rau APP-MCU kev sib txuas lus. Ib yam dab tsi los nyeem tus pin virtual ntawm MCU yog hu rau lub luag haujlwm no, qhov V1 tau hais txog kev siv tus lej virtual thiab param.asInt () tuav tus nqi tam sim no ntawm tus pin. Kev txwv tsis pub ua haujlwm tsuas yog txwv cov txiaj ntsig tuaj (kev nyab xeeb ua ntej: D).

BLYNK_WRITE (V1) {

// StepH t = millis (); current_mode = txwv (param.asInt (), 0, n_modes - 1); }

Txhawm rau sau tus lej pin rau Blynk APP koj tuaj yeem siv cov haujlwm hauv qab no:

int cov ntaub ntawv = getBatteryVoltage ();

Blynk.virtualWrite (V2, cov ntaub ntawv);

Koj yuav tau txais cov ntaub ntawv ntau ntxiv txog qhov no hauv Arduino kos duab!
