Pawg Dot Matrix no tau tsim los ntawm peb MAX7219 uas tuaj yeem qhia ib tsab ntawv lossis tus lej sib txuas ua ke. Qhov haujlwm Arduino no yog ua raws lub vev xaib no. Los ntawm lub vev xaib dhau los, Kuv tau ntxiv 2 ntau Dot Matrix, ib lub pob, thiab ib tus hais lus. Thaum cov ntawv lossis tus lej tab tom qhia, los ntawm nias lub pob thiab tuav nws, tus hais lus tuaj yeem tsim lub suab kom luag tib neeg mloog. Txhua qhov haujlwm tau ua thiab muaj nyob hauv ib lub thawv, ua kom yooj yim rau nqa mus los.
Kauj Ruam 1: Npaj Cov Khoom
- 3 8x8 Dot Matrix (MAX7219)
- 1 Pawg Thawj Coj
- 1 Arduino Leonardo
- Dhia Hlau
- Cardboard (Qhov loj me yuav txawv)
- Riam riam
- 1 Blue Resistor
- 1 Khawm
- 1 Tus Hais Lus
- Daim kab xev
- Kua nplaum
Kauj ruam 2: Txiav Txheej Txheej
1. Txiav ib daim duab plaub 10cm x 3.3cm nyob nruab nrab ntawm daim duab ntawv
2. Txiav lub voj voos uas muaj lub vojvoog ntawm 1.5cm ib sab ntawm lub duab plaub, tawm 2.5cm nyob nruab nrab
(Thawj daim duab yog lub ntsej muag uas koj yuav tsum tau tsom, nws siv yuav tsum muab Dot Matrix thiab khawm sab hauv, tab sis tsis txhob muab lawv tso rau hauv theem no)
3. Txiav ob daim 24.5cm x 10cm daim (Daim duab thib ob)
4. Txiav ob daim 13cm x 10cm daim (Daim duab thib ob)
5. Xaiv ib qho ntawm 13cm x 10cm thooj thiab txiav 6.5cm x 2cm qhov kom cia cov xov hlau tawm (Daim duab thib peb)
Kauj Ruam 3: Txuas Dot Matrix (MAX7219)
Npaj 3 Dot Matrix hauv qib no. Muaj ob sab rau txhua Dot Matrix: ib sab nrog ntsuab thiab ib sab tsis muaj ntsuab. Thaum txuas Dot Matrix ua ke, Dot Matrix yuav tsum txuas nrog ob sab sib txawv, raws li qhia hauv daim duab; Lub ntsiab lus ib qho nrog nws yuav muaj xov txuas nrog rau sab tsis muaj ntsuab, thiab lwm qhov nrog cov xov hlau txuas ntawm sab nrog ntsuab. VCC yuav tsum txuas nrog VCC, GND yuav tsum txuas nrog GND, DIN yuav tsum txuas nrog DIN, thiab ntxiv rau. Rov ua cov no kom txog thaum koj muaj peb Dot Matrix txuas nrog ib leeg.
Kauj Ruam 4: Txuas Dot Matrix rau Circuit Board
Siv 5 dhia xov hlau uas tuaj yeem txuas Dot Matrix thiab Pawg Mov Ci. Xaiv Dot Matrix ntawm sab xis los ua ib qho uas txuas rau Lub Rooj Mov Mov. Thaum tsib lub xov hlau txuas nrog rau ntawm Pawg Cij, cia:
- VCC txuas mus rau qhov zoo ib yam kab rov tav
- GND txuas rau GND ib feem ntawm Arduino
- DIN txuas rau Digital Pin 11
- CS txuas rau Digital Pin 10
- CLK txuas rau Digital Pin 13
Kauj ruam 5: Khawm
Txuas qhov zoo thiab qhov tsis zoo ntawm lub pob mus rau Pawg Cij. Siv cov tshuaj tiv thaiv xiav los txuas qhov tsis zoo ntawm lub pob mus rau kab rov tav tsis zoo ntawm Pawg Cij, thiab siv xaim thiab txuas qhov tsis zoo kab rov tav rau GND ntawm Arduino. Txuas qhov zoo ntawm lub pob mus rau kab rov tav zoo, thiab siv lwm lub xov hlau los txuas qhov kab rov tav zoo rau 5V ntawm Arduino. Thaum kawg, los ntawm qhov tsis zoo ntawm lub pob, siv xaim thiab txuas nws rau Digital Pin 2 ntawm Arduino.
Kauj Ruam 6: Hais Lus & Lwm Tus
Txuas qhov zoo ntawm tus hais lus rau Digital Pin 6 ntawm Arduino, thiab tsis zoo ntawm tus hais lus rau GND. Tsis tas li, siv xaim txuas txuas Digital Pin 0 mus rau kab rov tav zoo ntawm Pawg Cij.
Kauj Ruam 7: Ua ke
Tom qab txuas cov xov hlau thiab ua cov txheej sab nrauv, qib kawg yog ua lub thawv. Ntawm thawj daim duab los qhia (nrog lub duab plaub thiab lub voj voos me me), tso peb qho Dot Matrix thiab khawm (Daim duab 1). Ua kom ntseeg tau tias Dot Matrix ua raws qhov ua ntu zus thiab tib qho kev qhia. Kaw ob daim ntawv ntawv loj tshaj plaws (24.5cm x 10cm) ntawm qhov ntev ntawm thawj daim ntawv los xij, tom qab ntawd lo cov ntawv me me ntawm daim ntawv dav (13cm x 10cm). Thaum kawg, lo tus hais lus sab xis saum lub qhov ua hauv daim duab los me me.
Kauj Ruam 8: Sau tus lej
Sau tus lej no thiab txuas rau koj Arduino kom pib!
