Cov lus qhia no yog rau Arduino pib. Nov yog ib qho ntawm kuv cov phiaj xwm ua ntej nrog Arduino. Kuv nyiam heev thaum kuv ua nws thiab vam tias koj yuav nyiam nws ib yam. Qhov ntxim nyiam tshaj plaws ntawm txoj haujlwm no yog "Wireless control". Thiab qhov ntawd dhau los ntawm ib qho IR chaw taws teeb yooj yim muaj nyob hauv peb lub tsev. Tej zaum nws yuav yog TV chaw taws teeb lossis AC chaw taws teeb lossis lwm yam IR chaw taws teeb. Hauv txoj haujlwm no peb yuav pom txoj hauv kev ua haujlwm ntawm lub chaw taws teeb infrared thiab txiav txim siab nws lub teeb liab nrog kev pab los ntawm ARDUINO thiab TSOP 1738, nws yog lub tshuab txais hluav taws xob thoob ntiaj teb. Qhov TSOP 1738 no ua haujlwm nrog rau feem ntau ntawm cov duab infrared.

Koj tuaj yeem pom qhov project video hauv qhov txuas hauv qab no:

Kauj ruam 1:

Kauj Ruam 2: Cov Lus Cim

Hauv daim duab thaum kuv nias ib lub pob ntawm cov chaw taws teeb koj tuaj yeem pom lub teeb liab liab LED ntsais muag. txhais tau hais tias cov chaw taws teeb tso lub teeb liab infrared thaum twg kuv nias lub pob. Txawm li cas los peb tsis tuaj yeem pom lub teeb no nrog qhov muag liab qab.

Lub teeb liab no muaj pawg ON thiab OFF lossis koj tuaj yeem hais HIGH thiab LOW. Peb tuaj yeem hu pawg no ntawm ON thiab OFF raws li cov qauv teeb liab. Txhua lub khawm nws muaj nws tus qauv tshwj xeeb. Yog li thaum twg peb nias lub pob tshwj xeeb peb tau txais cov cim tshwj xeeb uas tau muab rau lub pob ntawd nkaus xwb. Yog li qhov no yog txhua yam hais txog IR chaw taws teeb.

Tam sim no nws yog lub sijhawm tau txais lub teeb liab. Peb lub hom phiaj yog txhawm rau txheeb xyuas cov cim siab thiab qis li 1 thiab 0. Hauv qhov no peb tuaj yeem hloov cov qauv teeb liab mus rau hauv cov ntaub ntawv. ARDUINO thiab TSOP 1738 yuav ua qhov ntawd rau peb.

Lub tshuab txais hluav taws xob yuav tau txais lub teeb liab los ntawm tej thaj chaw deb thiab muab rau arduino. Tom qab ntawd arduino yuav tshuaj xyuas lub teeb liab tau txais thiab hloov nws mus rau hauv cov ntaub ntawv hex. Thaum peb hloov lub teeb liab infrared rau hauv cov ntaub ntawv, peb tuaj yeem yooj yim txheej txheem cov ntaub ntawv ntawd thiab ua txhua txoj haujlwm raws li qhov peb xav tau.

Kauj Ruam 3: Txiav Txim Koj Txoj Haujlwm Tswj

Hauv qhov xwm txheej no lub hom phiaj yog tswj hwm digital digital output ntawm Arduino nrog lub TV nyob deb. Los sawv cev digital HIGH/LOW Kuv tau siv 3 LEDs - Liab, Daj thiab Ntsuab. Cov kev ua raws cai muaj raws li hauv qab no:

Qhib 'ON' LEDs hauv ib ntu tshwj xeeb (RED, GREEN, BLUE) thaum khawm "Volume up" khawm txhua lub sijhawm.

Qhib 'OFF' LEDs hauv ib ntu tshwj xeeb (XEEB, GREEN, RED) thaum lub pob "Volume down" raug nias txhua lub sijhawm.

Tab sis cov nyees khawm saum toj no yuav ua haujlwm tsuas yog thaum lub kaw lus qhib los ntawm nias ON/OFF khawm. Yog tias koj nias lub ON/OFF khawm thaum lub kaw lus twb ON lawm ces tag nrho lub kaw lus yuav kaw thiab tua tag nrho cov LEDs.

Thov saib Algorithm kom nkag siab zoo dua.

Kauj Ruam 4: Cov Khoom Npe
