Kev Pom Qhov Muag Pom Kev Siv Infrared Sensor: 5 Kauj Ruam

2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:28

Kuv siv lub ntsuas hluav taws xob txhawm rau nkag siab qhov muag txav thiab tswj LED.

Kuv ua qhov muag nrog daim kab xev LED NeoPixel.

Kauj Ruam 1: Tsab Cai Lij Choj

Kuv siv ob lub ntsuas QTR - 1A rau qhov muag taug qab. Pom nrog Arduino thiab tswj hwm LED.

Cheebtsam

• SparkFun Arduino Pro Mini 328 - 5V/16MHz
• Adafruit LiIon/LiPoly Backpack Ntxiv-Ntxiv rau Pro Trinket/ItsyBitsy
• Roj teeb LiPo
• NeoPixel sawb
• QTR-1A Reflectance Sensor

Kauj Ruam 2: NeoPixel LED Qhov Muag Pob

NeoPixel LED daim kab xev tau siv. LED yog 68 chav nyob.

LED tau tsau rau lub tais nrog daim kab xev ob tog thiab xaim.

Kauj Ruam 3: Chav Sensor

Kuv siv ob lub ntsuas QTR - 1A rau qhov muag taug qab. QTR - 1A tau muab tso rau ntawm daim ntawv yas ntawm qhov deb ntawm qhov dav ntawm lub qhov muag.

Ib feem ntawm lub sensor thiab lub microcontroller ib feem tau tsau rau lub tsom iav nrog daim clip raws.

Kauj ruam 4: Arduino Code

Thaum lub iris nce mus txog ib lub sensor, lub teeb pom kev zoo txo qis thiab lub txiaj ntsig tus nqi nce. Hloov pauv, thaum lub qhov muag txav mus deb, lub teeb pom kev nce ntxiv thiab qhov txiaj ntsig ntawm daim duab tsom iav poob qis.

Txoj cai thiab sab laug txav ntawm cov menyuam kawm ntawv ntawm LED qhov muag pom qhov nce thiab txo ntawm ib tus nqi sensor thiab tswj nws. Thaum ntsais muag, ob qho tib si qhov txiaj ntsig qis dua, yog li yog ob lub ntsuas qhov ntsuas qis ib txhij, daim tawv muag ntawm lub qhov muag LED yuav nqes mus.

Kuv siv lub tsev qiv ntawv hauv qab no.
