Kauj Ruam 3: Tau Txais Cov Khoom Siv Software

Koj yuav tsum xub rub tawm Arduino IDE dawb

Arduino Web Editor tsis ua haujlwm nrog NodeMCU thaum lub sijhawm kuv sau qhov no, yog li koj yuav tsum teeb tsa IDE rau koj lub khoos phis tawj.

Koj kuj tseem yuav tsum tuav cov ntaub ntawv NearBot los ntawm www. MakerSa.ga - Cov ntaub ntawv rub tawm txuas rau qhov haujlwm no tau teev nyob rau ntawm qhov chaw ntawd.

Kauj ruam 4: Nruab Drivers thiab Board Profiles

Sab hauv Zip NearBot koj rub tawm thiab unzipped yuav yog tus tsav tsheb rau NodeMCU module. Nruab cov ntawd rau koj lub computer.

Yog tias cov ntawd tsis ua haujlwm rau koj, koj yuav tuaj yeem nrhiav CH340G tsav tsheb ntawm wemos.cc/downloads

Koj NodeMCU yuav tsis siv CH340G nti, yog li koj yuav xav tawm tswv yim nrog tus tsav tsheb uas koj tab tom nrhiav, thiab kuv yuav teb nrog qhov rub tawm txuas rau tus tsav ntawd.

1. Tom ntej no, qhib Arduino IDE thiab mus rau File PreferencesAdministrative Boards Manager hauv Arduino IDE.
2. Paste cov cai hauv qab no muaj:
3. Nyem OK kom kaw qhov nyiam tab.
4. Mus rau cov cuab yeej thiab pawg thawj coj saib, thiab tom qab ntawd xaiv tus thawj tswj hwm pawg thawj coj saib.
5. Nkag mus rau "esp8266 los ntawm esp8266 zej zog" thiab teeb tsa software rau Arduino.

Thaum tag nrho cov txheej txheem saum toj no tau ua tiav peb tau npaj rau phiaj xwm peb esp8266 NodeMCU microcontroller nrog Arduino IDE!

Kauj Ruam 5: Qee Cov Ntaub Ntawv Pab Tau

Koj tuaj yeem pom nws yooj yim los xam tawm qhov NodeMCU version uas koj muaj. Nov yog phau ntawv sib piv:

frightanic.com/iot/comparison-of-esp8266-nodemcu-development-boards/

Txhua qhov version muaj tus lej sib txawv. Kuv yuav lub v3 (Lolin) version vim tias nws muaj 5V tso tus pin rau lub zog rau Servo lub cev muaj zog. Thaum kawg kuv siv lub 3 volt lub hwj chim hloov pauv rau kev nyab xeeb (Lub NodeMCU I/O pins tsis yog 5V zam), tab sis koj yuav xav siv 5V tus pin vim tias cov cuab yeej siv hom servo motors tau teev tseg rau 4.5 txog 5 volt zog.

Kauj Ruam 6: Thauj Cov Code rau NodeMCU

1. Txuas NodeMCU rau hauv koj lub computer siv ib qho micro USB cable.
2. Qhib Arduino IDE, thiab hauv qab "Boards", xaiv "ESP12E", thiab COM chaw nres nkoj rau NodeMCU.
3. Hauv IDE, mus rau FileOpen thiab xauj cov ntawv zip yav tas los rub tawm los ntawm makersa.ga kom qhib Arduino kos duab hu ua "ProximityActuator013017DonovanMagryta.ino"
4. Tom qab ntawd, hloov kab kab ntawv uas muaj qhov no ntxiv lub npe thiab tus password ntawm koj lub teeb WiFi. Xav paub ntau ntxiv hauv qab no! Piv txwv li:

const char* ssid = "mywifi"; // Muab koj lub npe hotspot tso rau hauv kab lus

const char* password = "mywifipassword"; // Muab koj lo lus zais hotspot tso rau hauv kab lus

Tom qab ntawv nyem "upload" txhawm rau nyem qhov chaws mus rau NodeMCU pawg thawj coj.

NearBot siv lub teeb ci WiFi lub hnab nqa los txheeb xyuas koj thiab kwv yees nrug deb. Ib yam li cov yuam sij nyob ze qee lub tsheb tshiab muaj qhov qhib lub qhov rooj rau lub tsheb thaum koj mus txog.

Koj tuaj yeem siv koj lub xov tooj ntawm tes xov tooj ntawm tes hotspot ua lub teeb, lossis hloov pauv siv ESP-01 WiFi tus nqi pheej yig siv los ntawm ib lub roj teeb AAA lossis lub roj teeb lithium 3.7v me me. Tsis tas yuav tsum tau teeb tsa ESP-01, nws ua rau lub hom phiaj hotspot thaum nws tau qhib. Daim duab qhia hluav taws xob rau qhov ntawd tau qhia ntawm theem no.

Kauj Ruam 7: Txuas tus Servo rau NodeMCU

Koj yuav xav tau qee lub xov hlau jumper los ntsaws qhov servo rau hauv NodeMCU V3.

Daim duab qhia chaw yog yooj yim.

Pin D0 rau lub teeb liab hauv cov hlau lead (lub teeb xim daj tshaj plaws ntawm qhov kev pabcuam. Feem ntau yog daj lossis dawb.)

Pin 3V lossis tus pin VO rau 5V cov hlau lead nkag (thib ob lub teeb xim xim tshaj plaws ntawm qhov kev pabcuam, feem ntau yog liab lossis txiv kab ntxwv.)

Pin GND rau hauv av (cov xim dub tshaj plaws ntawm qhov kev pabcuam, feem ntau yog xim av lossis xim dub.)

Kauj Ruam 8: Txhim Kho Tus NearBot

Txoj cai hloov pauv lub teeb liab mus rau kev kwv yees deb. Nws ua haujlwm tau zoo rau cov tshuaj tiv thaiv nrug tsawg dua 2 meters lossis 6.5 ko taw. Vim tias nws yog kev hloov pauv ncaj qha, nws tsis yooj yim rau kev nyob deb dua 3 metres vim nws tuaj yeem muaj peev xwm ua tau nrog txoj hauv kev suav tau zoo dua. Ntxiv rau qhov ntawd tom qab.

Tej zaum koj yuav xav hloov kho qhov chaw servo horn (caj npab dawb me me uas txav) nyob rau qhov chaw. Qhov no yog ua tiav los ntawm kev yooj yim unscrewing lub caj npab servo nrog tus ntsia hlau, thiab rov muab tso rau nws.

Ib feem tom ntej yog txhawm rau kho qhov siab tshaj plaws thiab qib qis tshaj ntawm kev txav mus los siv cov cai.

Qhov no tuaj yeem ua tiav los ntawm kev hloov cov lej muaj nyob hauv kab uas zoo li no:

myservo.write (10); // txav servo caj npab mus rau 10 degrees kev sib hloov

Koj tseem tuaj yeem kho lub teeb liab lub zog hloov pauv los ntawm kev hloov tus lej tsis zoo hauv kab uas zoo li no:

yog (rssi> -30 && rssi <-5) {// Yog tias lub teeb liab muaj zog dua -30, thiab tsis muaj zog dua -5. tom qab ntawd ua cov hauv qab no …

Kauj Ruam 9: Nws Ua Haujlwm Li Cas

1. NearBot xub txuas rau lub hotspot ua ntej raws li cov neeg siv mus.
2. Nws txheeb xyuas RSSI (tau txais lub teeb liab lub zog) thiab hloov qhov ntawd mus rau kwv yees li deb.
3. Thaum qhov kev ncua deb nyob hauv thaj tsam tshwj xeeb, nws txav lub cav servo caj npab mus rau txoj haujlwm 1.
4. Txwv tsis pub, servo motor tau txav mus rau txoj haujlwm 2.

Thaum kuv sim qhov no, qhov RSSI tuning (-50) txav cov servo mus rau txoj haujlwm 1 thaum qhov deb yog 0 txog 1.5 meter nrog ESP-01 lub teeb lossis lub xov tooj hotspot hauv kuv lub hnab tshos.

RSSI feem ntau poob hauv qhov ntau ntawm -90 txog -20, nrog -20 yog lub zog tshaj plaws ntawm lub teeb liab.

Yog tias koj qhib Arduino IDE Serial Monitor thaum lub NearBot tau txuas rau hauv lub khoos phis tawj, nws yuav tso tawm lub teeb liab lub zog thiab ua rau cov ntsiab lus nyob rau lub sijhawm tiag tiag rau koj kom muaj txiaj ntsig zoo.

Nov yog tus lej ua tiav:

Kauj Ruam 10: Koj Yuav Tsum Paub …

Tsis lees paub:

Tam sim no rov ua dua ntawm Txoj Cai NearBot ua haujlwm tau zoo rau kev ncua deb tsawg dua 2 meters lossis 6.5 ko taw. Tshaj li qhov ntawd, nws tau txais qhov tseeb dua, tab sis tseem ua haujlwm.

Qhov no tuaj yeem kho tau, tab sis tam sim no kuv tsis paub yuav ua li cas. Kuv yuav nyiam nws yog tias ib tus neeg yuav ua haujlwm nrog kuv yog li kuv tuaj yeem hloov kho cov lus qhia no nrog cov txheej txheem tseeb dua ntawm kev suav nrug!

Cov kev txuas no tuaj yeem siv tau yooj yim: YouTuber CNLohr txhim kho qhov deb thiab txoj haujlwm paub qhov tseeb firmware rau ESP8266 nrog kev ua tiav tsawg:

Espressif tau tsim Lub Sijhawm Dav Dav Kev Tshawb Fawb Kev Tshawb Fawb uas yuav ua haujlwm nrog Arduino IDE rau ESP8266, tab sis tsis tau tso nws tawm:

SubPos txoj haujlwm tso rau siv ESP8266 cov qauv thiab Txoj Kev Poob Xeem, uas yog qhov kuv tsis paub yuav siv li cas hauv Arduino IDE:

Kuv pom ib qho piv txwv hauv Java lus, tab sis kuv tsis paub yuav rov ua li cas yog Arduino IDE:

nrug deb = Math.pow (10.0, ((double) (tx_pwr/10)) - rx_pwr - 10*Math.log10 (4*Math. PI/(c/zaus)))/(20*mu)));
