Cov ntsuas cua yog qhov zoo tshaj plaws los ua haujlwm ib puag ncig nrog DIY cov khoom siv hluav taws xob thiab qhov no yog qhov qhia thib ob ntawm cov lus qhia uas tsim cov ntsuas sib txawv sib xws nrog ntau lub microcontrollers. Hauv cov lus qhia yav dhau los, Kuv tau qhia koj yuav ua li cas txhawm rau tsim lub tshuab qaij digital. Hauv cov lus qhia no, Kuv yuav qhia koj yuav ua li cas thiaj tsim Kov Sensor. Qhov no muaj ntau yam kev siv xws li Touch Controlled keyboards, doorbells, thiab lwm yam.
Cov lus qhia no yuav xav tau cov txuj ci sib txuas nws yog qhov yooj yim kawm paub txhawm thiab muaj ntau yam yeeb yaj kiab YouTube uas qhia koj yuav ua li cas.
Kauj Ruam 1: Nqi Khoom
Nov yog cov npe ntawm yam koj xav tau kom pib nrog cov lus qhia no.
- LM358 IB
- 10K Kaub
- LED
- 330 Ohm tus tiv thaiv
- PCB (Tsis teb los tau)
- Txuas Txuas
- 5v Hwj chim Mov
- Cov qhob cij
- Soldering Hlau
- Soldering Hlau
- Soldering Flux
- Multimeter (Tsis teb los tau)
Kauj Ruam 2: Tshaj Tawm Circuit
Lub Circuit Court yog qhov yooj yim heev, lub plawv ntawm Circuit yog LM358 IC, IC no yog siv los tshuaj xyuas thaum lub phaj tooj liab tau kov. Cov phaj tooj liab yog lub thaiv me me ntawm PCB uas yog siv rau kev kos tawm cov kab hluav taws xob. LM358 muaj qhov hluav taws xob ntau ntawm 3V txog 32V, uas tuaj yeem siv tau yooj yim nrog ntau lub microcontrollers.
Lub lauj kaub 10K tuaj yeem siv los hloov qhov rhiab heev ntawm lub Circuit Court, yog tias cov coj tseem nyob ON txawm tias tsis kov lub phaj sib txawv lub lauj kaub kom txog thaum LED tua.
Kauj ruam 3: TADAAA !! cov zis
Yog tias LED tsis lo rau ntawm Copperplate, siv cov ntawv xuab zeb lossis cov ntaub ntawv los ua kom lub ntsej muag ntxhib thiab tom qab ntawd ntws kom lo cov xaim hlau txuas mus rau ntawm lub rooj tsavxwm.
Tom qab koj tau sim tawm lub Circuit Court ntawm lub khob cij tom ntej koj tuaj yeem tsim PCB tawm ntawm nws, muaj ob txoj hauv kev koj tuaj yeem ua qhov ntawd yuav yog tsim Arduino daim thaiv thiab lwm qhov yuav ua PCBs me me uas tuaj yeem ntsaws rau hauv lub khob cij Arduino tsab thaiv.
Yog tias koj muaj lus nug, thov tawm lus hauv qab no lossis PM rau kuv thiab kuv yuav sim pab koj.
