Koj yuav tsum tau suav sau cov cai hauv Arduino program, yog li tam sim no nyem lub pob upload thiab nws yuav tsum pib xa mus rau Arduino board (koj tuaj yeem pom cov txiv kab ntxwv TX thiab RX LED ci ntawm lub Arduino board yog tias qhov no tshwm sim). Yog tias koj tau txais qhov yuam kev uas nws tsis teb ua ntej thawb lub khawm pib dua ib lub Arduino board (qhov hloov DIP me ntsis, tom qab koj thawb qhov no koj muaj li 6 vib nas this txhawm rau xa cov lej ua ntej nws rov pib dua), yog tias nws tseem tsis ua haujlwm, xyuas kom tseeb tias koj teeb tsa USB tsav tsheb kom raug (lawv nyob hauv daim nplaub tshev tsav tsheb hauv daim nplaub tshev Arduino koj rub tawm). Yog tias koj tseem tsis tuaj yeem ua haujlwm, sab laj nrog Arduino Rooj Sib Tham thiab thov kev pab, lawv tuaj yeem coj koj los ntawm yam koj xav tau ua. Yog tias txhua yam ua tau zoo koj lub khoos phis tawj yuav tsum tau pib li ntawm 10 vib nas this, thiab yog tias lub roj teeb AA raug them thiab teeb tsa, lub cav yuav tsum qhib thiab yog tias Sonar pom qee yam tsis pub dhau 16 ntiv tes qhov taw qhia daj yuav qhib thiab lub log raug yuav thim rov qab rau ib nrab ib pliag. Tam sim no koj tuaj yeem tshem lub USB cable, hloov lub jumper rau EXT, ntsaws rau hauv Power Jack thiab muab tso rau hauv av. Yog tias koj tau ua txhua yam kom raug tam sim no, tam sim no koj yuav muaj koj tus kheej qhov teeb meem zam kev siv neeg hlau! Yog tias koj muaj lus nug lossis lus pom (lossis yog tias kuv tso qee yam tseem ceeb tawm uas kuv tej zaum tau ua) tsuas yog tso kuv cov lus hauv kab lus. Tsis tas li yog tias koj muaj cov lus nug ntsig txog neeg hlau Kuv qhia tias koj koom nrog Society of Robots Forum uas kuv yog tus tswv cuab, thiab ib tus ntawm cov neeg yuav muaj kev zoo siab los teb koj cov lus nug! Zoo siab Robots!

Kauj Ruam 6: Ntxiv Infrared Sensors

Yog li tam sim no koj muaj neeg hlau ua haujlwm… tab sis nws tsuas tuaj yeem tig mus rau sab xis, thiab nws tseem muaj txoj hauv kev zoo ntawm kev ua haujlwm. Peb yuav kho qhov no li cas? Los ntawm kev siv ob sab sensors. Txij li tau txais ob lub tshuab ntsuas hluav taws xob ntau dua yuav kim heev, thiab tsis hais txog overkill, peb yuav siv ob lub ntsej muag ntse GP2Y0A21YK Kev Ntsuas Kev Ntsuas Siab. Cov no yog lub kaum ntse ntse yog li nws yuav muab rau peb pom dav dua. Thaum peb tsuas yog siv lub Ultrasonic sensor, qhov pib yog 16 ntiv tes, qhov no yog chav ntau, tab sis nws tsim nyog. Raws li koj tuaj yeem pom hauv daim duab hauv qab no, lub sonar yuav pom thaj tsam dav ntawm Walbot thaum nws nyob deb li 16 ntiv tes. Tab sis yog tias Walbot nyob hauv ib lub ces kaum (nrog rau phab ntsa nyob ntawm sab xis) nws yuav txheeb xyuas phab ntsa ua ntej tab sis tig mus rau hauv phab ntsa ntawm nws sab xis, thiab tau nyam. Txawm li cas los xij, yog tias peb muaj ob lub teeb pom kev deb deb ntawm ob sab ntawm lub sonar, peb tuaj yeem tshem tawm qhov sonars qhov muag tsis pom. Yog li tam sim no thaum Walbot nkag mus rau hauv ib lub ces kaum nws tuaj yeem txiav txim siab: 1. yog tias muaj teeb meem ua ntej thiab sab xis, lem sab laug. 2. yog tias muaj teeb meem ua ntej thiab sab laug, tig sab xis 3. yog tias muaj teeb meem ua ntej, ntawm sab xis thiab sab laug tig mus. Kuj tseem muaj qee yam uas peb tseem tsis tau hais txog, thiab qhov ntawd yog txhua qhov kev ntsuas tsis muaj zog. Sonar siv lub suab los laij dab tsi ua ntej ntawm nws, tab sis yuav ua li cas yog tias nws taw tes rau qee yam uas tsis cuam tshuam txog lub suab zoo, xws li hauv ncoo? Infrared siv lub teeb (peb tsis tuaj yeem pom nws) kom pom tias muaj dab tsi nyob ntawm nws xub ntiag, tab sis yuav ua li cas yog tias nws taw tes ntawm qee yam pleev xim dub? (Qhov ntxoov ntxoo dub yog qhov tsis muaj lub teeb, nws qhov kev xav tsis cuam tshuam rau lub teeb.) Ua ke ob lub ntsuas no tuaj yeem hais daws qhov tsis muaj zog, yog li tsuas yog txoj hauv kev Walbot yuav plam ib yam dab tsi nyob rau hauv nws, yuav yog nws yog lub suab dub nqus khoom Koj tuaj yeem pom yuav ua li cas ob qhov kev ntxiv me me no tuaj yeem pab Walbot zoo kawg. Tam sim no cia ntxiv cov ntsuas no rau Walbot. Step 1. Tau txais cov ntsuas! Kuv tso qhov txuas kom tau txais lawv saum toj no. Kuv kuj qhia koj kom tau txais 3-tus pin JST Cable rau Sharp Sensors vim tias lawv zoo nkauj heev mus nrhiav lwm qhov. Tam sim no hla ib lub lim tiam ua ntej thaum UPS tus txiv neej xa lawv, thiab cia ua haujlwm. Ua ntej koj xav tau ib txoj hauv kev rau mount lawv. Koj yuav tsum tau ua tus ncej rau lawv, Kuv tau ua kuv li ntawm ib txoj hlua ntawm txhuas, tab sis nws tsis muaj teeb meem tiag. Koj tuaj yeem sim theej cov duab ntawm kuv lub bracket, txhua yam ua haujlwm ntev li nws haum thiab tuav nws nyob hauv qhov chaw. Kauj Ruam 2: Txuas lub sensor rau lub bracket. Ntsia rau sab xub ntiag ob lub 8-32 lub hau ntswj kom txaus thiaj li muaj qhov chaw nyob nruab nrab ntawm qhov sawv ntsug thiab lub hauv paus. Ntsuas lub sensor rau hauv qhov chaw thiab ntsia nws rov qab ua ke. Kauj Ruam 3: rub cov xov hlau hla mus rau saum. Ntawm koj daim ntawv tiv thaiv PCB muaj ob txheej ntawm 3 qhov nyob rau sab xub ntiag ntawm lub rooj tsav xwm sau npe INFRA1 thiab INFRA2. Muab cov xaim liab txuas rau lub qhov uas sau tias VCC (lub qhov ze rau IN hauv INFRA), xaim cov xaim dub mus rau nruab nrab qhov, thiab xaim cov xaim dawb mus rau lub qhov kawg sau tias Ana2 lossis Ana3 (qhov ze rau RA hauv INFRA). Koj kuj tseem tuaj yeem xaiv siv cov kab sib txuas sib txuas uas tsis siv cov xov hlau txuas ncaj qha mus rau pawg thawj coj saib. Ua ke thiab xa qhov no rau koj li Walbot, thiab nws yuav tsum ntse dua li yav tas los! Nco tseg: Kuv tsis tau muaj sijhawm ntau los ntsuas cov cai tshiab, yog li yog tias ib tus neeg pom dab tsi tsis raug nrog nws lossis pom ib txoj hauv kev los ua kom nws zoo dua tsuas yog tawm lus tawm.
