2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:29

Nyob zoo, Nov yog kev qhia, yuav ua li cas kuv tsim tau lub tshuab nqus pa DIY portable. Kuv tsim ib lub thawv rau qhov haujlwm no.

Nta ntawm lub cuab yeej:

- ntsuas qhov tseeb concentration ntawm ethanol

- qhia pom qib ntawm cov pa roj tiag hauv 8 channel LED zaub

Yuav siv video li cas:

Cov ntaub ntawv kaw:

Arduino thiab Fritzing qhov chaws:

Yuav siv li cas

· Qhib lub cuab yeej nrog qhov hloov

· Tos ntev li ntev tau tsuas yog 2 LEDs nyob (cua sov hauv lub ntsuas cua yuav tsum sov)

· Tus nqi ntsuas tau qhia tsis tu ncua

· Tshuab rau hauv lub sensor tsawg kawg 3 vib nas this

· Tos thiab nyeem tus nqi

Kauj ruam 2: Sib dhos

Nqa tag nrho cov khoom siv thiab txuas lawv raws li cov txheej txheem. Siv DIY Prototype PCB thiab txuas txhua yam, siv xov hlau txuas PIN-s. LEDs module yuav tsum tau muab muag rau sab nraum qab ntawm Arduino pawg thawj coj kom txuag chaw.

Txhawm rau txheeb xyuas nws ua haujlwm, siv ib qho cawv thiab tso lub iav qhib tom ntej ntawm lub ntsuas, nws yuav tsum qhib txhua lub LEDs.

Kauj Ruam 3: Software / Vaj Tsev

Software

Txuas Arduino board rau PC. Siv Arduino IDE txhawm rau suav qhov upload qhov program mus rau Arduino. Cov cai yog tag nrho ntawm cov lus pom.

Arduino thiab Fritzing qhov chaws:

Vaj tse

Tsim vaj tsev los tiv thaiv hluav taws xob kom puas los ntawm kev kov. Lub tsev tuaj yeem yog 3D luam tawm lossis cov thawv yas me me.

Cov ntaub ntawv kaw:

Lossis koj tuaj yeem xaws ib lub tsev, siv cov lus qhia no:
