Yuav luag 39 lab tus tib neeg hauv ntiaj teb no dig muag niaj hnub no. Feem ntau ntawm lawv siv tus pas nrig dawb los yog dig muag-pas rau kev pab. Hauv cov lus qhia no, peb yuav ua kom ntse dig muag dig-pas uas tsis yog tsuas yog pab taug kev qhov muag tsis pom tab sis tseem paub txog ib puag ncig ib puag ncig thiab ceeb toom yog tias muaj ib yam khoom/teeb meem los ze dhau.
Lub suab tsis ua raws txoj cai ntawm kev xav zoo li lub teeb. Lub hauv paus ntsiab lus no yog siv hauv SONAR raws li kev tshawb pom ntau thiab kev taw qhia. Hauv txoj haujlwm no, peb tab tom tsim qhov me me SONAR module uas yuav haum rau hauv tus kheej lo (peb tab tom hloov kho nws kom dig muag-lo).
Kauj Ruam 1: Cov Npe Khoom
- Arduino-Nano
- HCSR04 Ultrasound Sensor
- 9V Roj Teeb
- Buzzer
- Laub Khawm/Hloov
- Poj Niam Rau Poj Niam Jumper Xov
- Kua nplaum/Adhesive (Rau Cov Khoom Yas Feem Ntau)
- 3D Luam Tshooj (Txuas Hauv Cov Kauj Ruam hauv qab no)
Kauj Ruam 2: 3D Luam Ntawv+Sib Sau Ua Ke
Rub tawm STL cov ntaub ntawv los ntawm cov kab ntawv txuas hauv qab no
- Selfie-Stick:
- Arduino Nano Case:
- Ultrasonic Sensor Housing: https://www.thingiverse.com/thing: 708627
3D luam tawm cov ntu no thiab sib sau ua ke tus kheej. Ntawm no peb tab tom siv selfie-stick ua tus dig muag lo.
Tso Arduino nano hauv nws rooj plaub thiab tseem nce lub ntsuas hluav taws xob hauv nws lub tsev.
Kauj Ruam 3: Ua Sonar Circuit
Txuas HCSR04 sensor, buzzer rau Arduino pins raws li tau piav qhia hauv kab lus muab los ntawm cov xov hlau txuas. Txuas roj teeb thiab hloov mus rau Arduino Vin, GND. Muab cov koob digital tsuas yog siv rau, koj tuaj yeem ua qhov Circuit Court no raws li koj xaiv/yooj yim siv lwm tus lej digital (Arduino code yuav raug hloov raws li)
Kauj Ruam 4: Mounting Sonar Assembly ntawm Stick
Txawm hais tias koj tuaj yeem tso lub sonar Circuit rau ntawm tus pas raws li qhov koj tsim thiab yooj yim, cov duab no tsuas yog siv los yog ib txoj hauv kev ua li ntawd. Cov nplaum/Adhesive yuav xav tau rau koom nrog cov khoom yas. Nco ntsoov ntim cov xov hlau uas tsis sib haum nyob rau hauv ib chav uas muaj peev xwm los ntawm kev kaw lawv thiab tseem ruaj ntseg rau qhov muag tsis pom lo kom ua lub rooj sib dhos ua ke thiab nqa tau.
Kauj Ruam 5: Arduino Code+Ua Haujlwm
Raws li tus pas no yog ua raws cov qauv me me sonar nws siv qhov yooj yim thiab tus nqi qis ultrasound sensor HCSR04 los tsim/ua rau lub suab mem tes uas zoo ib yam li cov roj hmab pob ntaus rau txhua qhov chaw thiab thaws rov qab mus rau lub suab ncho-pin. lub sijhawm rau kev sib kis+kev txais tos yog txiav txim siab los ntawm lub moos txuas hluav taws xob hauv lub ntsuas no.
Ntxiv mus, lub sijhawm no yog siv los xam nrug deb ntawm qhov teeb meem uas siv cov qauv yooj yim heev thiab yooj yim
Ze = Ceev*sijhawm
Xav txog qhov tseeb tias lub sijhawm siv sijhawm yog ob npaug ntawm lub sijhawm ntsuas los ntawm qhov ntsuas qhov teeb meem thiab hloov pauv ntawm chav nyob los ntawm microseconds mus rau vib nas this, meters rau centimeters, suab nrawm hauv huab cua = 340 m/s cov mis tawm los
Nrug = 0.034*ntev/2
Rub tawm qhov muab Arduino cov ntaub ntawv hauv sonar module ntawm dig muag-stick thiab zoo siab nws tau npaj lawm !!!! Koj tuaj yeem sau koj tus kheej Arduino code ua kev hloov pauv raws li kev ua haujlwm thiab teeb tsa hauv Circuit, thov qhia tawm.
