Kauj Ruam 3: Tsim Lub Thawv

Ua ntej tshaj plaws peb yuav tsim lub thawv ntoo thiab daim phiaj LED. Qhov ntev ntawm lub voos xwmfab tau teev tseg los ntawm qhov deb ntawm pixel ntawm LED sawb. Hauv qhov no pixel muaj qhov nrug ntawm 3, 4cm, yog li lub voos xwmfab yuav tsum yog 34 x 34 x 34 cm. Koj yuav txuag ntau lub sijhawm siv qhov ntev no, vim tias koj xav tau tsis txhob txiav cov kab txaij tom qab txhua lub pixel thiab muab rov qab los ua ke los ntawm txoj kab me me.

Txhua yam tuaj ua ke nrog qee cov kua nplaum ntoo. Koj yuav tsum ua haujlwm kom raug vim ua rau cov ntaub ntawv acrylic zoo sib xws nyob saum lub thawv ntoo. Nws tau txais kev yooj yim dua nrog qee tus neeg tuaj yeem pab dawb nyob ib puag ncig koj, lossis tsuas yog siv tus thav duab thav duab zoo li kuv tau ua.

Cov npoo ntawm daim phiaj thiab daim phiaj nws tus kheej yog ua los ntawm cov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom dej (HDF). Siv lub rooj pom yog qhov kev xaiv zoo tshaj vim tias koj yuav tsum txiav ntau dua 100 daim ntawm lawv. Koj tuaj yeem pom qhov ntev hauv daim duab saum toj no. Daim phiaj xav tau qhov sib txawv me me (kwv yees li 0, 3cm) txhua txhua 3, 4cm txhawm rau kom tau x thiab y coj ua ke. Thaum koj ua tiav, koj tuaj yeem tso cov ntug rau lub voos xwmfab thiab kho lawv nrog ntau cov ntoo kua nplaum. Nws nyuaj me ntsis, tshwj xeeb tshaj yog vim tias lawv yuav tsum muaj lub kaum sab xis ze li 45 degrees. Ua ntej koj tuaj yeem xa daim phiaj rau lub voos xwmfab koj yuav tsum tau ntxiv cov hlua LED.

Kauj Ruam 4: Cov Khoom Siv Hluav Taws Xob

Cov LED ib sab ntawm ib sab mus ib ncig ntawm lub voos xwmfab, yog li txiav 10 kab ntawv nrog qhov ntev ntawm 40 pixel. Rau cov LEDs saum lub voos xwmfab txiav 10 kab ntawv nrog qhov ntev ntawm 10 pixel. Ceev faj kom kho cov kab kom raug los ntawm kev hais txog lub xub ntawm lawv. Thaum koj tshem cov kua nplaum tawm ntawm lub voos xwmfab nws yuav tsis tuav zoo li thawj zaug.

Cov khoom siv fais fab tau tsau nrog qee qhov ntsia hlau ntawm ob sab ntawm sab hauv. Cov hlua hluav taws xob los ntawm LEDs tau nkag mus rau hauv lub thawv los ntawm qee qhov me me nyob ze ntawm txhua kab sawb LED.

Tus tswj hwm muaj Teensy 3.2, ESP8266 thiab Teensy audio board, uas tsis tas yuav khiav lub voos xwmfab. DHT11 tsuas yog txhawm rau txheeb xyuas qhov ntsuas kub sab hauv lub voos xwmfab tab sis tom qab kuaj ntau yam txog ob peb teev kuv tuaj yeem hais tias koj tuaj yeem tso nws tawm.

Ntawm lub davhlau ya nyob twg koj tuaj yeem pom lub hwj chim txuas nrog rau lub zog hloov pauv (thaum kuv pom tau tias qhov no tsis yog qhov chaw zoo tshaj plaws rau kev hloov pauv nws lig dhau lawm). Lub USB nkaus yog rau kev ua haujlwm Teensy. Lub suab-hauv mus rau Teensy audio board rau ua LEDs rau cov nkauj. Tag nrho cov no los ua ke ntawm kev thaj yeeb nyab xeeb me me ntawm aryl iav tuav los ntawm ob daim ntawv txhuas. Tsuas yog pom qhov no hauv lub nkas -las, koj tuaj yeem siv txhua yam koj xav tau vim tias nws tau npog los ntawm cov vaj huam sib luag hauv qab ntoo thiab tsis pab ua kom zoo li lub voos xwmfab.

Nco ntsoov tias ib qho LED siv 60mA, tag nrho yog 30A! Ceev faj thaum koj nqes lawv! Koj yuav tsum txheeb xyuas tag nrho koj cov kev sib tw ua ntej koj txuas lawv rau lub zog siv!

Kauj Ruam 5: Kev Sib Txuas thiab Coding

Cov LEDs tau txuas nrog ua ob daim ntawv ntawm tus pin 3 thiab 20 ntawm Teensy. Thawj qhov yog matrix nyob rau sab saum toj (10x10, 100pixels) thiab qhov thib ob yog sab (40x10, 400pixels). LEDs ntawm cov lej saum toj kawg nkaus tau koom ua ke hauv zigzag tus qauv, txhais tau tias cov xub ntawm kab ntawv yuav tsum nyob hauv cov lus qhia sib txawv rau txhua kab txaij, hos cov kab txaij LED ntawm ob sab sib koom ua ke tib yam. Saib cov duab, kab liab yuav qhia koj yuav ua li cas txuas Dout ntawm thawj kab ntawv mus rau Din ntawm tus tom ntej no, vam tias yuav pab koj nkag siab txog kev sib koom ua ke.

Txog qhov ua yeeb yaj kiab thiab kev ua si Kuv tau hloov ob qhov kev kawm ua ib qho los ntawm qhov loj ntawm 10x50 siv cov haujlwm hauv qab no:

void setXYPixel (byte x, byte y, CRGB c) {

yog (x <= 39) matrix_bottom (x, y) = c; lwm matrix_top (x - 40, y) = c; } // kawg setXYPixel ()

Rau Snake game koj yuav tsum tau siv qee qhov tshwj xeeb:

• Thaum tus nab nab tsoo rau kab saum toj kawg nkaus ntawm sab matrix nws yuav tsum hloov mus rau matrix nyob rau sab saud.
• Thaum tus nab nab tsoo ib qho kawg ntawm sab saum toj matrix nws yuav tsum hloov mus rau hauv qab matrix.
• Thaum tus nab nab tsoo qhov kawg lossis thawj kab ntawm sab matrix nws yuav tsum hloov mus rau thawj kab lus kawg.

Txog Tetris kev ua si koj xav tau qee yam zoo sib xws rau qhov no rau thaj chaw pib ntawm kaum sab laug:

void setXYPixel (byte x, byte y, CRGB c) {

yog (y <10) matrix_top (x, y) = c; lwm matrix_bottom (x + 10, 19 - y) = c; } // kawg setXYPixel ()

Kauj Ruam 6: Daim npog Acrylic

Nyuaj nyuaj dua li lub thawv ntoo vim qhov tuab me dua, tab sis nrog lub sijhawm txaus thiab lub tswv yim zoo rau khaws lub voos xwmfab ua ke thaum cov kua nplaum ua tawv koj yuav tau txais qhov no ua ke. Kuv xav tsis thoob txog lub zog ntawm cov kua nplaum acrylic (Acrifix), yog li kuv xav tias koj tsis tas yuav txhawj xeeb txog qhov xwm txheej tawg.
