• Hall-effect magnetic thiab discrete optical khub sensors (piv txwv li QRD1114) tau tshuaj xyuas. Ntau yam ib txwm tsis txaus. Tso tseg.
• Adafruit #2821 Feather HUZZAH nrog ESP8266 uas tshaj tawm rau Adafruit IO dashboard. Lub sijhawm tshuaj ntsuam ntxiv tsis yog qhov tus neeg siv khoom xav tau. Tso tseg.

3.xSensor ua haujlwm:

Cov kab ntawv no tseem tshawb nrhiav lwm txoj hauv kev xws li siv lub tshuab stepper ua tus lej zoo ib yam li Cov Lus Qhia no. Ua tau tab sis rau lub teeb liab qis ntawm RPM qis. Kev ua haujlwm me ntsis ntxiv yuav hloov qhov no mus rau qhov kev daws teeb meem, tab sis nws tsis yog qhov yooj yim rov kho dua nrog ib puag ncig hamster uas twb muaj lawm. Tso tseg.

4.1 Kev kho vajtse/software piav qhia hauv Phau Ntawv Qhia no.

5.x Ntau Sensor ua haujlwm:

Txheeb Xyuas Ntsej Muag GP2Y0D810Z0F Digital Distance Sensor nrog Pololu Carrier thaum tseem siv Adafruit #2771 Feather 32U4 thiab Adafruit #3130 14 ntu LED zaub Featherwing. Ua haujlwm zoo. Ua code tsis tseem ceeb. Siv lub zog ntau dua li Vishay TSSP4038 daws. Tso tseg.

6.x Yav tom ntej?

• Hloov qee qhov HWT cov ntaub thaiv npog rau cov thawj coj rau Adafruit #2771 Feather nrog cov ntawv tshaj tawm.
• Hloov qhov qhib/tua hloov nrog lub laub khawm hloov txuas nrog Feather reset.
• ATSAMD21 Cortex M0 microcontroller, xws li pom ntawm Adafruit #2772 Feather M0 Basic Proto, muaj ntau yam ntxim nyiam. Kuv yuav saib qhov no ze ntawm lwm qhov kev hloov kho.
• Vishay muaj tus qauv tshiab IR sensor, TSSP94038. Nws muaj qhov xav tau tam sim no qis dua thiab cov lus teb tau piav qhia ntau dua.
