Kauj ruam 2: Zaj dab neeg

Taw qhia

Kuv xav ntsuas qhov ntsuas kub ntawm cov kua los ntawm kev tsim lub ntsuas sov yooj yim. Los ntawm kev siv XinaBox xChips Kuv tuaj yeem ua tiav qhov no nrog kev txheeb ze yooj yim. Kuv siv SX02 cov lus qhia sib piv xChip uas lees txais 0 - 3.3V, CC01 xChip raws li tawm ntawm ATmega328P thiab OD01 OLED zaub xChip los saib kuv qhov ntsuas kub.

Kauj Ruam 3: Rub Cov Ntaub Ntawv Tsim Nyog

Koj yuav xav tau cov tsev qiv ntawv thiab software hauv qab no:

• xSX0X- Lub tsev qiv ntawv Analogue input sensor
• xOD01 - OLED lub tsev qiv ntawv tso saib
• Arduino IDE - Kev txhim kho ib puag ncig

Nyem rau qhov no kom pom yuav ua li cas rau nruab cov tsev qiv ntawv.

Thaum koj tau teeb tsa Arduino IDE, qhib nws thiab xaiv "Arduino Pro lossis Pro Mini" ua lub rooj tsavxwm txhawm rau rub koj cov haujlwm rau. Kuj tseem ua kom ntseeg tau tias xaiv ATmega328P (5V, 16MHz). Saib duab hauv qab no.

Xaiv Arduino Pro lossis Pro Mini board thiab ATmega328P (5V, 16MHz) processor

Kauj ruam 4: Sib sau ua ke

Nyem tus programmer xChip, IP01, thiab ATmega328P raws CC01 xChip ua ke siv XC10 tsheb npav txuas raws li qhia hauv qab no. Txhawm rau rub mus rau CC01 koj yuav tsum tso cov hloov pauv hauv 'A' thiab 'DCE' txoj haujlwm feem.

IP01 thiab CC01 nyem ua ke

Tom ntej no, coj koj 10kΩ resistor thiab ntsia hlau ib kawg hauv lub davhlau ya nyob twg cim "IN" thiab lwm qhov kawg hauv av davhlau ya nyob twg, "GND", ntawm SX02. Coj cov coj mus rau qhov ntsuas kub ntawm lub ntsuas cua thiab ntswj ib qho kawg hauv Vcc, "3.3V", thiab lwm qhov kawg hauv "IN" davhlau ya nyob twg. Saib cov duab hauv qab no.

SX02 kev sib txuas

Tam sim no ua ke OD01 thiab SX02 nrog CC01 los ntawm kev nyem lawv ua ke siv XC10 tsheb npav txuas. Saib hauv qab no. Cov xim nyiaj hauv daim duab yog lub ntsuas cua sov.

Ua kom tiav chav rau kev ua haujlwm

Kauj Ruam 5: Txoj Haujlwm

Ntxig chav nyob rau hauv USB chaw nres nkoj ntawm koj lub computer. Rub tawm lossis luam thiab muab cov cai hauv qab no tso rau hauv koj li Arduino IDE. Sau thiab xa cov cai rau koj pawg thawj coj. Thaum rub tawm koj qhov program yuav tsum pib ua haujlwm. Yog tias koj sojntsuam nyob ntawm chav sov, koj yuav tsum ntsuas ± 25 ° C ntawm OLED zaub raws li qhia hauv qab no.

Tom qab rub tawm saib xyuas chav sov ntawm OLED zaub

Kauj Ruam 6: Cov Ntsuas Kub Ntsuas

Tshem tawm chav tsev ntawm koj lub computer. Sib cais chav tsev thiab rov qab siv nws PU01 dua li IP01. Tam sim no coj koj 5V USB lub zog nqa hluav taws xob xws li lub txhab nyiaj hluav taws xob lossis zoo sib xws thiab ntxig qhov sib dhos tshiab rau hauv. Tam sim no koj muaj koj tus kheej lub ntsuas cua txias txias nrog qhov raug zoo. Saib daim duab npog kom pom nws ua haujlwm. Kuv ntsuas dej kub hauv ib khob. Cov duab hauv qab no qhia koj chav ua tiav.

Ua kom tiav chav tsev suav nrog CC01, OD01, SX02 thiab PU02.

Kauj Ruam 7: Xaus

Txoj haujlwm no tau siv sijhawm 10 feeb los sib sau ua ke thiab lwm 20 feeb rau txoj haujlwm. tsuas yog ib qho kev tiv thaiv uas yuav tsum tau muaj yog tus tiv thaiv. XChips tsuas yog nyem ua ke ua rau nws yooj yim heev.
