Hnub no kuv yuav piav qhia li cas kuv ua daim ntawv ntsuas no uas yog tswj los ntawm raspberry pi thiab siv los ntawm 5V lub zog xa khoom. Nws siv kev sib xyaw ntawm ws2811 thiab ws2812b leds rau teeb pom kev zoo thiab cov qauv tsim los ntawm plywood thiab liab ntoo qhib. Txog kev piav qhia ntawm teeb tsa cov cai thiab Circuit koj tuaj yeem saib cov vis dis aus hauv qab no:
Khoom siv:
- ws 2811 leds
- ws2812b wb
- Raspberry Pi Zero (tuaj yeem siv txhua yam)
- 5V Cov Hluav Taws Xob
- SN74HCT125 Cov Hluav Taws Xob Hluav Taws Xob - dhia hluav taws xob los ntawm raspberry pi teeb liab kom muaj qhov hluav taws xob tsim nyog rau coj sawb (Kuv ib txwm tau txais kuv cov ntu ntu los ntawm Digikey)
Kauj Ruam 1: Tsim Tus Qauv rau Cov Lus Cim
Thawj kauj ruam yog los tsim cov qauv rau cov qhab nias. Kuv siv daim ntoo thuv plywood rau lub ntsej muag thiab ntoo qhib liab rau ob sab. Cov qhab nias muaj 3 ntu rau lub sijhawm, lub npe ntawm pab pawg hauv tsev, thiab lub npe pab pawg uas nyob deb. Muaj 4 ntu tag nrho los tso saib cov qhab nia rau txhua pab pawg, thiab peb yuav tsum tho qhov 15 qhov rau txhua tus lej (3 kab los ntawm 5 kab).
Kauj ruam 2: Tsim Circuit Court
Lub voj voog no nce qib qhov hluav taws xob los ntawm raspberry pi cov ntaub ntawv tus pin rau cov ntaub ntawv tus pin ntawm ws2812b leds. Lub qhov hluav taws xob tsis zoo los ntawm cov ntaub ntawv tus pin yog 3.3V tab sis cov leds xav tias yuav muaj 5V teeb liab, yog li peb siv cov kev sib txuas ua ke los ua qhov no rau peb raws li tau piav qhia hauv daim duab kos.
Kauj Ruam 3: Sib sau ua ke
Txhua ntawm 7 ntu ntu coj mus rau hauv cov qauv nab, thiab qhov kawg ntawm ib ntu txuas nrog rau qhov pib ntawm lwm qhov. Tom qab muab cov leds, peb txuas cov khoom siv hluav taws xob rau sab nraub qaum nrog cov kua nplaum kub thiab cov ntsia hlau.
Kauj Ruam 4: Txhim Kho Txoj Cai thiab Cia Nws Rip
Tom qab koj rub tawm cov cai los ntawm cov chaw cia hauv qab no, teeb tsa cov lus txhais tas li kom phim koj cov ntaub ntawv siv thiab txaus siab rau qhov tsim tshiab!
