Ib feem rau Thawj Lub Tsev Qiv Ntawv
Ib feem rau Thawj Lub Tsev Qiv Ntawv

Kuv tab tom ua cov phiaj xwm txuas rau tus ua cim cim i2c adapter.

Txheeb xyuas qhov hloov tshiab ntawm kuv lub xaib.

Tam sim no kuv ntxiv cov txheej txheem txuas txuas txuas los siv lub tsev qiv ntawv qub tsis yog kuv rab rawg

LiquidCrystal Arduino tsev qiv ntawv rau tus ua cim LCD qhia, forked project rau tsim tus kheej lub tswv yim los kawm pcf8574.

Hauv qhov project github koj tuaj yeem pom cov duab, duab thiab cov lej qiv ntawv.

Nov yog daim vis dis aus ntawm milled PCB muab los ntawm Fritzing breadboard schema.

Kauj ruam 1: Ib feem rau Thawj Lub Tsev Qiv Ntawv

Koj tuaj yeem pom cov khoom siv rau lub tsev qiv ntawv qub (tsis yog kuv rab rawg) los ntawm eBay.

Tam sim no ntawm no koj tuaj yeem pom tib txoj kev sib txuas uas muaj tib tus cwj pwm.

Kauj Ruam 2: Daim Duab Hluav Taws Xob: Teeb Tom Qab

Daim duab thaiv kab: Lub teeb rov qab
Daim duab thaiv kab: Lub teeb rov qab

Raws li koj tuaj yeem pom hauv kab duab kab kuv txuas rau P7 tus NPN (2N2222) transistor kom qhib/lov tes taw teeb pom kev zoo.

Kauj Ruam 3: Daim Kab Xaim: Chaw Nyob

Daim duab thaiv: Chaw nyob
Daim duab thaiv: Chaw nyob
Daim duab thaiv: Chaw nyob
Daim duab thaiv: Chaw nyob

Kuv teeb qhov chaw nyob txhua qhov qis (koj tuaj yeem txuas Nws raws li koj xav tau, hauv cov ntawv koj tuaj yeem pom txhua qhov teeb tsa).

Kuv pom cov duab muaj txiaj ntsig zoo uas tshawb nrhiav txhua i2c cov khoom txuas, siv qhov no los tshuaj xyuas qhov chaw nyob.

Kauj Ruam 4: Daim Duab Hlau: Trimmer

Daim duab kab hlau: Trimmer
Daim duab kab hlau: Trimmer

Txhawm rau xaiv qhov sib txawv koj yuav tsum tau ntxiv 10k trimmer.

Kauj Ruam 5: Daim Kab Xaim: Hloov Cov Ntaub Ntawv

Daim duab thaiv kab: Hloov cov ntaub ntawv
Daim duab thaiv kab: Hloov cov ntaub ntawv

Xiav thiab daj hlau yog xa cov ntaub ntawv mus rau lub cuab yeej, Kuv tsis txuas lub cuab yeej raws li lub tsev qiv ntawv qub yog li kuv yuav tsum tau nkhaus lub lib thiab ntxiv qee qhov kev hloov pauv.

Kauj Ruam 6: Hloov mus rau Lib Thawj

Hloov mus rau Thawj Lib

Raws li koj tuaj yeem pom hauv daim duab kuv hloov qee qhov me ntsis (sab xis mus rau sab laug), thiab ntawm sab xis kuv muab tsau tshaj tawm ntawm Pab Kom, RW, Sau Npe Xaiv, thiab Rov qab teeb tus pin.

Yog tias koj xav tau koj tuaj yeem rov kho cov phiaj xwm mus rau qhov qub. Yog tias kuv pom qee lub sijhawm kuv yuav ua Nws rau koj (thiab sim nws) yog li koj tuaj yeem siv lub tsev qiv ntawv qub.

Kauj Ruam 7: Thawj Lib thiab Kev Sib Txuas Schema

Thawj Lib thiab Kev Sib Txuas Schema

Kuv rov tsim cov phiaj xwm sib txuas ntawm lub tsev qiv ntawv qub, yog li koj tuaj yeem siv cov tsev qiv ntawv txheem nrog rau qhov no

Kauj Ruam 8: Daim Duab Hlau: SDA SCL

Cov Duab Kab Hlau: SDA SCL
Cov Duab Kab Hlau: SDA SCL

Cov hlua hlau yog SDA SCL tus pin ntawm kuv tus arduino.

Kauj Ruam 9: Daim Duab Hlau

Raws li koj tuaj yeem pom daim duab kab hluav taws xob yog qhov yooj yim heev, dua li kuv sim tsim nws ntawm tsab ntawv pov thawj ntawm cov phiaj xwm.

Kauj Ruam 10: Pawg Thawj Coj

Nws tsis zoo nkauj heev tab sis nws ua haujlwm.

Kauj Ruam 11: Milling PCB

Los ntawm cov txheej txheem kuv tsim PCB thiab kuv sim zeb PCB nrog kuv lub router (Kuv tab tom pib qhia yuav ua li cas zeb PCB).

Kauj ruam 12: Ua tsaug
