Txoj haujlwm no yog lub txee los ntawm 1-99 rau kev tsim nrog ob-10 LED Bargraph thiab Arduino Uno. 2-Digit LED Bargraph Counter qhia txog kev ua haujlwm ntawm tus lej ntawm 2 tus lej uas LED Bargraphs sawv cev, ib tus kaum thiab lwm tus. Txhua ntu ntawm LED Bargraph sib haum rau chav nyob hauv sab xis kom txog thaum ua tiav 9 thaum kaum nyob rau sab laug kom txog thaum ua tiav 9 ib yam. Tom qab ntawd koj yeej muaj lub txee los ntawm 1-99.

Kauj Ruam 1: Cov Npe Khoom

1 Arduino UAS

2 10 LED Kab

1 PCB tus qauv

1 1X6 Header Arduino Shield

3 1X8 Header Arduino Shield

18 470 Ohm-Resistor

1 USB-B rau USB-A cable

Kauj ruam 2: Schematic

Nco tseg hauv koj cov phiaj xwm nce ntu LED hauv ob sab sib cuam tshuam vim tias lawv tsis siv thiab koj tsuas yog nyob hauv cuaj ntu ib yam li kaum tawm hauv ib qho.

Kauj Ruam 3: Pib Txoj Haujlwm

Txhawm rau pib koj txoj haujlwm, teeb tsa 1X6 & 1X8 qhov (socket) thiab txuas ntxiv rau lawv raws li daim duab ntawm txoj haujlwm. Tsis tas li, ntxig rau 10 LED Bargraphs cuam tshuam nrog lawv cov cathodes.

Kauj Ruam 4: Ua Haujlwm Nrog Cov

Teem cov resistors kom txuas nrog rau ib leeg thiab ze rau lawv tus kheej Arduino pins los ntawm D2 txog D10 hauv qab mus rau saum toj. Tom qab ntawd muab cov tshuaj tiv thaiv nruab nrab ntawm lawv sib xws 10 LED Bargraph thiab Arduino pins.

Kauj Ruam 5: Ua Haujlwm Nrog TheTens

Teem cov resistors kom txuas nrog kaum tawm thiab ze rau lawv cov Arduino tus pin los ntawm D11 txog D12, A5 rau A0, & D13. Tom qab ntawd muab cov tshuaj tiv thaiv nruab nrab ntawm lawv sib xws 10 LED Bargraph thiab Arduino pins. Thaum kawg, nco ntsoov txuas mus rau Arduino GND 10 LED Bargraph cathodes.

Kauj Ruam 6: Ua tiav Koj Txoj Haujlwm

Thaum ua tiav koj txoj haujlwm, mus ntsib:

Tom qab ntawd, koj tuaj yeem tso tus lej ntawm tus vev xaib tom ntej:
