TimeRuler yog lub sijhawm ntsuas qhov chaw ntsuas, siv cov txheej txheem pleev xim. Nws tuaj yeem siv rau kev lom zem, txhawm rau ntsuas kev nrawm nrawm hauv kev ncaws pob sib txawv lossis ua cov cuab yeej siv rau tsev kawm ntawv.

Koj xav tau dab tsi:

• Arduino UNO, lossis zoo sib xws
• 13ks ua. 3V ultra ci dome LED
• dhia xaim
• mini khob cij
• 9V roj teeb
• plywood
• ntoo nplaum
• phom phom
• tracing ntawv, ntawv dub, ntawv carbon
• nyiaj xim lossis daim iav iav
• fretsaw
• Lub koob yees duab nrog kev ua haujlwm ntev

Kauj Ruam 1: Txuas, Xeem

1. ntxig 11 LEDs rau hauv lub khob cij
2. txuas cov LEDs anode/ntev pins (+) nrog tus pin 3-13
3. txuas cov cathode/luv (-) pins rau GND.
4. qhib Arduino thiab qhib cov ntawv txuas nrog. Yog tias koj tsis muaj software, dua li rub tawm nws ntawm no.
5. disconnect lub roj teeb, txuas Arduino nrog koj lub computer ntawm USB cable muab.

6. ua tib zoo saib cov cai kom pom nws ua dab tsi. Thaum koj tab tom sim koj tuaj yeem teem sijhawm ntev dua yog li koj tuaj yeem tshawb xyuas yog tias LEDs tau teeb tsa kom raug ntawm qhov pom tau sai.

   int delt = 9; // ncua sijhawm 9 ms - teeb qhov no rau 99int blit = 0.1; // ncua sijhawm 0.1 ms - teeb tsa qhov no rau 1

7. upload cov cai rau Arduino thiab pom qhov tshwm sim

Kauj Ruam 2: Ua Lub Thawv

Ua ib lub thawv los ntawm plywood. Lub thawv ntawv sib dhos loj yog 62*85*77 mm (2.44*3.34*3.03 nti)

1. luam cov ntawv PDF uas txuas nrog
2. theej nrog kev pab ntawm cov ntawv carbon cov kab ntawv liab ntawm lub hau plywood.

3. theej nrog kev pab ntawm cov ntawv carbon cov qauv kab xiav rau ntawm daim ntawv tawv dub thiab txiav tawm cov duab kom zoo zoo. Khaws daim ntawv taug qab tom qab ntawm daim duab los qhia - qhov no yuav ua rau pom lub teeb ci. Cov kab xiav no tau ntxig rau 1 hli, vim tias nws nyuaj rau ua qhov tseeb hauv plywood.

4. Txiav 15 hli (0.59 nti) daim plywood dav dua cov kua nplaum ib ncig ntawm lub qhov. Koj tuaj yeem pleev xim rau xim tom qab lossis lo daim iav daim iav - cov txheej txheem no pab thaws ntau lub teeb tawm los ntawm lub qhov.

Kauj Ruam 3: Solder, Mount

1. Muab cov xov hlau txuas rau cov LEDs, dua li insulate
2. Kuaj LEDs los ntawm kev txhim kho lawv txhua tus hauv qhov yog. Yog tias yog, tshaj kho lawv nrog cov kua nplaum kub.
3. lo qee cov xim dub nyiam ua npuas ncauj rau sab nraum qab ntawm lub hau, yog li thaum koj kaw tsis muaj lub teeb tuaj yeem khiav ntawm ntug.
4. muab ib daim yas yas los pleev xim rau sab hauv qhov ntev tshaj plaws.

Kauj ruam 4: On-Off
