Kuv tau nyiam ua cov phiaj xwm nrog Arduinos, tab sis ntawm $ 30 ib daim koj cov phiaj xwm tuaj yeem kim. Yog li kuv xav qhia koj li cas koj tuaj yeem ua koj tus kheej Arduino los ntawm kos thiab txuag nyiaj ua nws. Ua koj tus kheej Arduino rau ib puag ncig $ 8. Txog cov lus qhia no kuv qhia koj yuav ua li cas ua ib qho ntawm lub khob cij thiab nrog nws ua tus ntsuas kub digital.
Yog xav paub ntau cov vis dis aus zoo li no thiab lwm qhov haujlwm DIY, nyem ntawm no.
Kauj Ruam 1: Qhov Chaw Koj Xav Tau rau Arduino:
- Daim Ntawv Loj Loj ($ 8 adafruit.com)
- 22 AWG Hlau lossis xov hlau txuas ($ 6 adafruit.com)
- 1 - 7805 Tus Tswj Hluav Taws Xob ($ 0.18 taydaelectronics.com)
- 2 - LEDs ($ 0.02 txhua taydaelectronics.com)
- 2 - 220 Ohm Resistors ($ 0.10 txhua taydaelectronics.com)
- 1 - 10k Ohm Resistor ($ 0.10 taydaelectronics.com)
- 2 - 10 uF Capacitors ($ 0.01 txhua taydaelectronics.com)
- 1 - 16 MHz Clock Crystal ($ 0.07 taydaelectronics.com)
- 2 - 22 pF Capacitors ($ 0.10 rau pob ntawm 10 taydaelectronics.com)
- 1 - Me Me Momentary Feem ntau Qhib "tawm" Khawm ($ 0.05 taydaelectronics.com)
- 1 - Breadboard -friendly 2.1mm DC chim jack thiab 9V Wall Wort nrog 2.1mm Plug (2.1mm jack $ 0.95 adafruit.com)
- 1 - ATMega328 nrog Bootloader ($ 6 adafruit.com lossis pheej yig lwm qhov chaw yog tias koj tuaj yeem ntxiv koj tus kheej bootloader)
Ntau ntawm cov ntu no koj tseem tuaj yeem yuav los ntawm Xov Tooj Cua. Piv txwv tias koj muaj lub khob cij, xaim, thiab txoj hauv kev rau txoj haujlwm (saib cov kauj ruam 4) Arduino qhov nqi tag nrho $ 7.71 +xa khoom.
