Hauv kab ntawv no kuv yuav qhia koj yuav ua li cas ntsuas ntsuas kub siv Bar Graph & Atmega328p. Cov ntawv yuav suav nrog txhua cov ntsiab lus xws li daim duab kos duab, PCB tsim, Coding, Sib dhos & Xeem. Kuv kuj tau suav nrog cov vis dis aus uas muaj txhua cov ntsiab lus.

Kauj Ruam 2: Daim duab Circuit Court, PCB Layout & Sketch

Lub Circuit Court tau tsim hauv KiCad. Tom qab tsim cov phiaj xwm kuv tsim PCB txheej txheem & tsim Gerber & Laum Cov Ntaub Ntawv. Tom qab ntawd xa cov Zip nplaub tshev uas muaj tag nrho Gerber & Drill cov ntaub ntawv hauv JLCPCB.com lub vev xaib rau kev tsim khoom (Leej twg muab 5 PCB's rau 2 $ nrog ib hnub thauj khoom).

Kos duab

Cov duab uas kuv tau siv yog daim duab yooj yim heev uas tuaj yeem nkag siab yooj yim. Thawj ntu ntawm daim duab (hais txog xim daj) yog siv los tshaj tawm & pib ua qhov hloov pauv. Kab tom ntej uas tau hais txog yog kom tau txais tus nqi sib piv los ntawm LM35. Ob kab tom ntej no yog siv los hloov tus nqi sib piv rau Celsius (kom paub ntau ntxiv txog cov mis thov nyem rau ntawm no). Kuv kuj tau suav nrog kab uas koj tuaj yeem siv tau yog tias koj xav tau tus nqi hauv Fahrenheit. Qhov kawg ntawm txoj cai yog yooj yim yog cov lus siv los qhib thiab tawm ntawm Bar Graph raws li qhov ntsuas kub.

Kauj Ruam 3: Kev Tsim Kho & Kev Xeem

Tom qab tau txais lub rooj tsavxwm los ntawm JLCPCB.com kuv tau teeb tsa lub rooj tsavxwm & txuas nws mus rau 5V DC fais fab mov. Atmega328 tau npaj ua ntej tes. Yog tias koj tsis paub yuav ua li cas rau program Atmega328p ces koj tuaj yeem xa cov vis dis aus no. Thov nco ntsoov lub cuab yeej no tau teeb tsa qhov ntsuas kub ntawm 25'C txog 34'C. Kuv kuj tau suav nrog kev sib piv ntawm ob qhov qauv qhia qhov kub thiab txias.
