Cov zaub no tuaj yeem tsim ua ib qho anode lossis cathode ntau. Cov khoom siv rau txoj haujlwm yog PCB, 29 LEDs ntawm 3mm, 8 tus tiv thaiv thiab 2 hla los ntawm poj niam lub taub hau rau arduino 1x6. DIY Seven Segment Display 2ʺ yog qhov zoo rau arduino cov haujlwm thiab tsim cov txee. Txawm li cas los xij, yog tias koj tsim lub txee, koj yuav tsum tso dawb tus lej lej zauv cim. Saib cov yees duab ntawm:
Kauj Ruam 1: Nqi Khoom
1 PCB 1.5ʺ x 3.5ʺ (Jameco PN: 105102) 29 LED's ntawm 3 mm 8 Resistors ntawm 200 ohm 2 Dhau-dhau poj niam lub taub hau rau Arduino 1 x 6
Kauj Ruam 2: Txoj Haujlwm Daim Duab
Hauv txoj haujlwm no, koj muaj kev xaiv los sib sau ua ke ib qho anode zaub lossis ib qho cathode uas pom zoo los ntawm qhov koj xav tau. Txheeb xyuas koj cov LED ua ntej siv lawv. Yuav siv lub roj teeb puag ncig ntawm 3 Volt.
Kauj Ruam 3: Npaj ntu "a"
Nco ntsoov tias koj yuav tsim ntu ntawm 4 LED's ua ke. Ntawd yog, koj yuav txuas ob qho tag nrho anodes thiab txhua cathodes los ntawm kev tawm dawb tsuas yog anode thiab cathode ntawm koj teeb ntawm 4 LED's. Txheeb xyuas cov LED ua ntej siv lawv. Tom ntej no, teeb tsa cov LED rau tsim ntu "a" ntawm koj cov zaub uas koj txiav txim siab ua. Piv txwv li, yog tias koj txiav txim siab los tsim ib qho kev sib txuas anode, koj yuav tsum tso dawb cathode rau kev txuas nrog cov tiv thaiv thaum koj xav tso dawb anode rau txuas nrog rau lwm qhov anodes los tsim cov npe nrov anode. Koj tuaj yeem siv lub roj teeb puag ncig ntawm 3V txhawm rau txheeb xyuas txhua ntu uas koj ua.
Kauj Ruam 4: Npaj ntu "b"
Txheeb cov LED "ua ntej txhim kho lawv. Tom qab tsim ntu" b "ntawm koj cov zaub, kos nws dua.
Kauj Ruam 5: Npaj ntu "f"
Kuaj 4 LED ntau dua ua ntej txuas rau lawv. Ua ntu ntu "f" thiab tshawb xyuas nws dua.
Kauj Ruam 6: Npaj ntu "g"
Coj 4 LED ntxiv thiab txheeb xyuas lawv ua ntej txhim kho lawv. Ua ntu ntu "g" thiab sim ua ntu ntu.
Kauj Ruam 7: Npaj ntu "c"
Txheeb 4 LED ntxiv ua ntej txuas rau lawv. Ua ntu "c" thiab sim nws dua.
Kauj Ruam 8: Npaj ntu "d"
Kuaj 4 LED ntau dua thiab tsim ntu "d". Tom ntej no, xyuas nws yog tias nws ua haujlwm. Nco ntsoov tias koj tuaj yeem siv lub roj teeb puag ncig ntawm 3 Volt rau kev tshuaj xyuas yog tias ntu tsim tau ua haujlwm raug.
Kauj Ruam 9: Npaj ntu "e"
Ua ntu ntu "e" los ntawm kev ntsuas cov LED ua ntej txhim kho lawv. Thaum koj sib sau ua ke teeb tsa ntawm LED, tshawb xyuas nws dua los txheeb xyuas nws txoj haujlwm.
Kauj Ruam 10: Npaj Lub Ntsiab Lus Ntsiab Lus (dp)
Coj lub LED kawg uas koj muaj rau tsim "dp", tab sis sim nws ua ntej thiab tom qab sib dhos nws.
Kauj Ruam 11: Txhim Kho Cov Tiv Thaiv
Nruab ib lub resistors ntawm 200 ohm los ntawm kev txheeb xyuas txuas ntxiv hauv koj lub Circuit Court thiab hauv qhov raug kom raug ua ntej txuas ntxiv nrog cov kauj ruam hauv qab no ntawm txoj haujlwm.
Kauj Ruam 12: Nruab Ib Tus Poj Niam Headers Pins 1 X 6
Nruab ib qho ntawm tus poj niam lub taub hau ntawm 1 x 6 thiab txuas qhov kawg pub dawb ntawm cov resistors ntawm ntu los ntawm "a" rau "e" thiab nquag anode (+) los ntawm kev txheeb xyuas txuas ntxiv tas li.
Kauj Ruam 13: Npaj Lwm Tus Poj Niam Headers Pins 1 X 6
Npaj lwm tus poj niam lub taub hau 1 X 6 los ntawm kev txiav cov pins uas koj tsis tas yuav tawm tsuas yog peb tus pin hauv koj tus poj niam lub taub hau. Xyuas cov duab.
Kauj Ruam 14: Ua tiav Koj Txoj Haujlwm
Ua kom tiav koj txoj haujlwm los ntawm kev tshuaj xyuas txhua ntu ntawm cov zaub los ntawm kev siv lub zog hluav taws xob ntawm 5 Volt.
