Cov zaub no yog 3 taw ntev, thiab tsuas yog siab dua ib txhais taw! Ntawd yog ib nrab ntawm qhov loj ntawm lub TV flatscreen! Ntxiv rau, txhua yam yog tswj los ntawm arduino, yog li koj tuaj yeem npaj nws kom ua lwm yam txias.
Yog li koj tseem tos dab tsi? Tau cov LEDs tawm thiab ua kom sov koj cov hlau txuas vim tias peb tab tom yuav ua 24X6 LED matrix!
Kauj Ruam 1: Yam Peb Xav Tau
- 1 Arduino pawg thawj coj saib
- 192 LEDs ntawm lub teeb
- 3 x 74HC595 hloov npe
- 28 91ohm resistors
- 81k tiv
- 8 2N3904 transistors
- 1 4017 xyoo kaum xyoo counter
- 1 teev board
Kauj Ruam 2: Schematics rau Led Matrix
Koj yuav tsum tau khoov txoj hauv kev zoo ntawm LED nqes mus rau lwm tus thiab ua kab, thiab txiav tawm cov kab uas koj tsis tau siv thiab sim ua kom muaj kev sib txuas qis li koj tuaj yeem tau txais, thiab koj ua qhov no rau txhua qhov ntawm cov coj zoo.
Tam sim no cov kev coj tsis zoo tau txuas nrog hauv kab ntawv thiab qhov ntawd ua rau qhov muag tsis zoo vim tias kab zoo nyob hauv txoj kev, yog li koj yuav tsum ua kom 90 degrees khoov nrog cov hlau tsis zoo thiab ua tus choj hla kab zoo mus rau qhov tsis zoo tom ntej, thiab ntxiv rau LEDs tom ntej.
