Tsis tuaj yeem nres kov koj lub ntsej muag? Khaws cov khoom siv hluav taws xob no rau ntawm lub npog ntsej muag uas koj muaj thiab koj yuav nco ntsoov tas li tsis txhob ua qhov ntawd.

Khoom siv

Koj yuav xav tau:

  • Arduino (Kuv siv Arduino Nano)
  • ultrasonic qib sensor
  • tus hais lus me me
  • amplification Circuit Court
  • xov hlau
  • laug
  • pawg thawj coj saib / pawg thawj coj saib

Kauj Ruam 1: Txhim Kho Lub Circuit Court ntawm Lub Rooj Mov Ci

Tsim Circuit Court ntawm Pawg Cij
Tsim Circuit Court ntawm Pawg Cij
Tsim Circuit Court ntawm Pawg Cij
Tsim Circuit Court ntawm Pawg Cij

Tsim lub Circuit Court raws li hauv daim duab.

Rau kev ua kom nrov nrov, siv txoj kev siv transistor lossis txoj kev uas kuv tau siv nrog LM386 kev sib xyaw ua ke.

Kauj Ruam 2: Txheej Txheem Koj "qw" Suab thiab Upload Code rau Koj Arduino

Rub tawm PCM Arduino lub tsev qiv ntawv.

Tom qab ntawv xa cov cai no rau koj Arduino.

Yog tias koj xav hloov lub suab nrov nrov rau koj tus kheej lub suab kaw, ua raws qhov kev qhia no txhawm rau ua koj li suab thiab hloov pauv ib feem ntawm cov cai.

Tam sim no, thaum koj txav qee yam ze rau ntawm lub ntsej muag lub ntsej muag ultrasonic, koj lub suab kaw yuav tsum ua si.
