Qhov no yog Kev Qhia txuas ntxiv qhov ntau ntawm TV-B-Gone zoo ib yam li Cov Lus Qhia no. Nws siv 12 Infrared-LEDs nrog lub roj teeb 9V. Hauv vib nas this koj tuaj yeem hloov lub teeb nyem txuas nrog ib leeg IR-LED kom muaj qhov loj me me rov qab lossis muab lwm qhov txuas ntxiv rau nws.
Kauj Ruam 1: Tau Cov Khoom
Koj xav tau:
- 1 TV-B-Gone
- 1 IC-qhov (socket)
- 1 optocoupler
- 12 IR-LEDs
- Roj teeb 19V
- 1 lub teeb nyem
- Cov khoom siv phom (riam, cov hlau txuas, xaim, thiab lwm yam)
Kauj Ruam 2: Hloov TV-B-Gone
Qhib rooj plaub ntawm koj lub TV-B-Gone thiab tsis muab muag rau IR-LED. tom qab ntawd txiav tawm ob tus pin ntawm IC-lub qhov (socket) thiab khoov tus pin. Muab qhov no tso rau qhov uas koj tau tshem lub LED. Ntxiv rau koj tuaj yeem tso qee cov kua nplaum nyob ib ncig ntawm tus pin kom tuav lawv nyob rau hauv qhov chaw. Yuav kom muaj peev xwm tso IR-LED rau hauv lub qhov (socket) koj yuav tsum txiav nws cov pins thiab kab sib chaws tus boarder ntawm LED kom haum los ntawm lub qhov hauv rooj plaub.
Kauj Ruam 3: Hloov Kho Lub Teeb
Tshem lub teeb qub thiab lub tsom iav. Txiav ib lub rooj tsav xwm hauv Circuit kom haum rau hauv lub teeb nyem. Ua IR-LEDs mus rau ntawm lub rooj tsavxwm nrog 4 uake. Qhov kawg ntawm kab yog txhua tus txuas nrog lub qhov hluav taws xob. (Cov kab mob ua los ntawm TV-B-Gone yog luv heev, yog li koj tuaj yeem txuas nws yam tsis muaj kev tawm tsam).
Kauj Ruam 4: Ntxig rau Optocoupler
Cov tswv yim-pins ntawm optocoupler txuas nrog lub xov hlau sab nraum lub teeb nyem. Ib qho ntawm cov pins tso tawm txuas nrog lub roj teeb, lwm qhov txuas nrog lub qhov (socket). Lwm Tus pin ntawm lub qhov (socket) txuas nrog lub roj teeb. Tsis txhob hnov qab cais cov pins.
Kauj Ruam 5: Muab Nws Ua Ke tig TV
Thaum kawg muab tag nrho ua ke. Kuaj nws los ntawm nias lub pob hauv TV-B-Gone thiab pom lub teeb pom kev zoo LED los ntawm lub koob yees duab.
