Kauj Ruam 33: Cov Lus Cim Qhia ntawm Circuit
Lub ntsuas hluav taws xob ntsuas siv IR LED/IR Photodiode khub.
IR LED ua haujlwm zoo li ib txwm LED. Cov hlau lead zoo (ntev dua lossis anode) txuas nrog qhov hluav taws xob zoo. Ntawm Arduino Nano, nws yog tus pin tso tawm teeb rau HIGH. Cov hmoov txhuas tsis zoo (luv dua lossis cathode) txuas nrog hauv av kom ua tiav cov Circuit Court. Txij li LEDs nkag siab rau qhov tam sim no ntau dhau, ib qho me me tiv thaiv tau muab tso ua ke nrog LED los txwv cov nqi tam sim no. Tus tiv thaiv no tuaj yeem nyob txhua qhov hauv Circuit Court, tab sis nws ua rau muaj kev nkag siab tshaj plaws los tso nws rau ntawm qhov zoo ntawm Circuit Court, txij li cov hlau lead tsis zoo koom nrog kev txuas hauv av nrog photodiode.
IR Photodiode coj zoo ib yam li lwm lub diode (suav nrog Lub Teeb Emitting Diodes LEDs) hauv qhov uas lawv tsuas yog siv hluav taws xob hauv ib qho kev taw qhia, thaiv hluav taws xob hauv qhov kev coj rov qab. Tias yog vim li cas nws thiaj tseem ceeb kom tau txais qhov polarity raug rau LEDs ua haujlwm.
Qhov sib txawv tseem ceeb nrog Photodiodes, yog thaum lawv pom lub teeb, cov photodiodes yuav tso cai rau hluav taws xob ntws ob txoj kev. Cov cuab yeej no yog siv los ua lub ntsuas hluav taws xob (hauv qhov no Lub Teeb Hluav Taws Xob lossis IR). IR Photodiode tau txuas nrog qhov tsis sib xws (hu ua rov qab tsis ncaj ncees) nrog qhov zoo 5V ntawm Arduino tus pin txuas nrog cov hlau tsis zoo ntawm photodiode thiab cov hlau lead zoo tau txuas nrog los ntawm cov xov hlau ib txwm nrog rau IR LED rau hauv av.
Tsis muaj lub teeb IR, IR photodiode thaiv hluav taws xob, tso cai rau Arduino tus pin nrog nws sab hauv rub tawm tus tiv thaiv nyob rau ntawm lub xeev HIGH. Thaum IR photodiode pom IR lub teeb, nws tso cai rau hluav taws xob ntws, tsaws tus pin thiab ua rau HIGH tus nqi ntawm tus pin photodiode poob qis rau hauv av ua rau FALLING ntug uas Arduino tuaj yeem tshawb pom.
Qhov kev hloov pauv ntawm lub xeev ntawm tus pin Arduino tau siv hauv daim duab los suav cov kev tawm tsam.
Cov kab xev ntawm txhuas daim kab xev ntawm cov txiv ntoo sib txuas, cuam tshuam txog IR lub teeb los ntawm ib txwm-ntawm IR LED rov qab mus rau IR photodiode txhua lub sijhawm nws tig dhau lub sensor.
Kauj Ruam 34: Cov Lus Cim ntawm Arduino Sketch
Arduino kos duab tsav lub OLED cov duab thiab ua ke ua ke rau IR LED/IR Photodiode sensor.
Daim Sketch pib OLED cov duab thoob plaws nws I2C (Inter-integrated Circuit) raws tu qauv.

Qhov kev txuas no txo tus naj npawb ntawm kev sib txuas ntawm Arduino thiab OLED zaub.
Nws mam li tig rau IR LED los ntawm kev teeb tsa tus pin HIGH muab 5V xav tau rau LED.
Nws txuas qhov kev cuam tshuam cuam tshuam rau tus pin uas hu ua thaum nws pom qhov kev hloov pauv uas tus pin lub xeev. Hauv qhov no qhov kev nce qib Revolution () muaj nuj nqi yog hu ua thaum twg pom FALLING ntug pom ntawm tus Pin 2.
Ib qho kev cuam tshuam cuam tshuam tsuas yog qhov nws cuam tshuam, nws cuam tshuam txhua yam uas tam sim no tau ua tiav, ua tiav txoj haujlwm thiab tom qab ntawd rov pib ua qhov tseeb uas nws tau cuam tshuam. Kev cuam tshuam kev ua haujlwm yuav tsum luv li sai tau, hauv qhov no nws tsuas yog ntxiv ib qho rau ntawm qhov sib txawv ntawm cov txee. Me ntsis Arduino Nano khiav ntawm 16Mhz - 16 lab mus rau ib pliag - txaus txaus txaus los daws qhov cuam tshuam ntawm 30, 000 RPM, uas tsuas yog 500 kiv puag ncig.
Lub Loop () muaj nuj nqi yog thawj qhov ua haujlwm rau ib qho Arduino kos duab. Nws tau txuas ntxiv hu ua, ntau thiab ntau dua ntev npaum li Arduino muaj lub zog. Nws tau txais lub sijhawm tam sim no, kuaj xyuas seb lub sijhawm tshwj xeeb tau dhau mus lawm (1/4 thib ob = 250 milliseconds). Yog li, nws hu rau updateDisplay () muaj nuj nqi los tso saib tus nqi RPM tshiab.
Lub voj ua haujlwm tseem yuav ua kom cov zaub poob qis tom qab 1 feeb thiab tua cov zaub tom qab 2 feeb - teeb tsa tau tag nrho hauv txoj cai.
Kev hloov kho tshiab () ua haujlwm hu ua calculRpm () muaj nuj nqi. Txoj haujlwm ntawd suav nrog suav cov kev tawm tsam qhov kev cuam tshuam cuam tshuam tau nce zuj zus thiab suav nrog RPM los ntawm kev txiav txim siab tus nqi ntawm kev tawm tsam ib lub sijhawm twg thiab suav qhov ntawd rau tus lej ntawm Kev Tawm Tsam Ib feeb.
Nws qhia txog tus lej tus lej thiab siv qee Lub Tsev Kawm Ntawv Qib Siab txhawm rau kos cov lus sib piv thiab qhov taw tes qhia kom pom qhov zoo ib yam.
Qhov ruaj khov nyob rau sab saum toj ntawm daim duab tuaj yeem hloov kho, yog tias koj xav tau RPM hu nrog qhov sib txawv loj thiab qhov tseem ceeb me.
Hloov kho ncua thiab nruab nrab ncua sijhawm kuj tseem tuaj yeem hloov kho.
