16 hnub thiab yim teev dhau los Kuv tau pib qhov haujlwm zoo no, ib txoj haujlwm uas muaj teeb meem thiab cov transistors. Tab sis dhau los ntawm txhua yam kuv tau kawm yam kuv tsis tau paub ua ntej … Tsuas yog tso dag kuv muaj qee qhov kev xav ntawm yuav ua dab tsi ua ntej kuv pib. Ua ntej koj pib ib qho kev lom zem hauv hluav taws xob ib txwm ua koj qhov kev tshawb fawb. Muaj ob ntu rau qhov no, tsim lub Txiaj Ntsig Txaus Ntshai LED matrix thiab tom qab ntawd yuav ua li cas khiav nrog 74hc595 ICs thiab Arduino. Kuv lub hom phiaj qub rau kev ua qhov no yog kuv xav tsim lub teeb pom kev LED thiab kawm paub siv nws li cas. Tom qab ntawd vim tias tib neeg feem ntau xav paub yog vim li cas tsim qee yam kuv txiav txim siab tig nws mus rau hauv lub tswb moos. Thiab yog tias koj tsis kudos rau koj! Cov cai yog txhua qhov qub yog li siv nws raws li koj thov, ua rau thov yog lo lus zoo.
Lub moos no ua dab tsi. Yog tias koj xav tau cov ntaub ntawv ntxiv nws yog lub moos… uas qhia lub sijhawm…. tsis hais lus tab sis … Ugh koj tau txais qhov kuv txhais tau tias. Tsis tas li nws muaj ob txheej tuaj yeem Tswb thiab txiav kom haum rau qhov ci tam sim no ntawm chav.
Cov kauj ruam
- Cov khoom siv
- LED arrays, multiplexing nws ua haujlwm li cas
- Tsim lub LED Matrix
- Tsim lub voj voog
- Rub tawm qhov program
- Teeb meem
- Xaus
Skillz
Yog muaj qee qhov txuj ci uas koj xav tau, ntawm no yog cov npe.
- Yuav ua li cas rau program Arduino.
- Yuav ua li cas thiaj li siv tau
- Yuav ua li cas ua raws li kab kos rau xaim. Saib seb kuv tau ua dab tsi? Ntse, txoj cai?
- Tsis txhob poob siab thiab txiav tawm thaum qee yam ua tsis raug.
Txhua yam no yooj yim ua tab sis koj yuav xav tau kev paub me ntsis hauv txhua qhov ua ntej sim qhov no, tshwj xeeb yog qhov kawg. Qhov no tseem ceeb heev. Thiab nco ntsoov "Yog tias koj tsis fricassee kib kib ib tug qaib." Kuv txhais tau tias "Yog tias koj tsis tau ua tiav thawj zaug sim dua." Kuv ib txwm tau txais ob qho sib xyaw ua ke, feem ntau vim tias kuv nyiam kib nqaij qaib.
Kauj ruam 1: Cov khoom siv
Nov yog txhua qhov koj xav tau.
1x Computer rau Program Arduino.
1 x Arduino. (Kuv siv Uno)
80x 5mm LEDs.
1x Real Time Clock (RTC) module.
1x Piezo Buzzer uas nrov txaus los tsa koj.
1 x Photo Resister. (Lub Teeb Ntsuas Tus Kheej)
16 x 330 ohm Resisters.
5 x 1k ohm Resisters.
3 x 10k ohm Resisters.
5 x NPN Transistors
2x 74hc595 Hloov Sau Npe.
2x Nyees khawm
1 x 10k Potentiometer
1x Pob ntawm Jumper xov hlau, pawg loj.
1x 830 tus pin Breadboard.
1x 400 tus pin Breadboard.
1x5v zog. (Kuv Uno muab lub zog txaus)
2x Xim ntawm 20 Gauge Hlau.
1x ntoo Board uas koj yuav haum rau.
1 x pin.
1 x Ruler
1 x Me rab koob lub qhov ntswg.
1x Hlau Cutters.
1x Soldering Hlau.
1x Rosin Core Solder.
1 x Carpenters Square. (Qhov no tsis xav tau tab sis pom zoo heev)
Tau kawg peb xub ua peb qhov Circuit Court ntawm lub khob cij. Kuv tab tom npaj yuav siv qee qhov perfboard thiab pob txha liab qab Arduino los ua qhov no mus tas li. Uas yuav tsuas yog xav tau ib daim ntawm perfboard thiab txhua ntu los ua pob txha liab qab Arduino. Koj tseem yuav xav tau tus ncej thaum kawg yog li pib xav txog qhov koj ua nws tawm, kuv yuav yog 3/8 plywood glued ua ke.
