2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:29
Hauv txoj haujlwm no, peb yuav tsim FM transmitter siv Arduino.
Kauj Ruam 1: Yam Koj Yuav Tsum Tau
- Ib qho arduino Nano, lossis ib qho Arduino ntawm koj xaiv.
- 16x2 Arduino LCD.
- Elechouse FM module V 2.0
- Ib lub khawm hloov
- Ib qho 220 Ohm resistor
- 500k Ohm kuj tsis paub meej resistor
- 50k Ohm kuj tsis paub meej resistor
- 10k Ohm kuj tsis paub meej resistor rau LCD
Kauj Ruam 2: Lub Rooj Sib Tham
Lub tswv yim rau ntu no yog ua kom tiav kev teeb tsa tag nrho ntawm peb qhov kev sib tham txhawm rau ua kom tiav lub hom phiaj, ua tus xa xov FM.
Pib los ntawm kev noj koj daim ntawv qhia zaub mov, qee tus dhia thiab koj Arduino. Nrhiav tus pin A0, A1, A4, A5, D2, D3, D4, D5, D9, D10, D11, Hauv av thiab 5V.
Thaum nyob peb yuav pib los ntawm kev sib txuas qhov sib txawv resistors uas yuav ua haujlwm li pob qhov rooj uas yav tom ntej yuav hloov pauv zaus peb xav xa mus rau. Tam sim no, nco ntsoov hauv daim ntawv teev npe peb qhov sib txawv resistors tau hais. Rau ntu no peb yuav siv 500k thiab 50k sawv daws. Ib txwm, 50k yuav ua haujlwm rau peb ua tus cim rau txhua chav ntawm zaus thiab 500k ib qho yuav ua haujlwm rau peb rau cim cim zauv.
Rau kev sib dhos, txuas nruab nrab lub davhlau ya nyob twg ntawm 500k qhov sib txawv resistor rau A0, sab laug dav hlau mus rau hauv av thiab sab xis rau 5V. Tom qab ntawd, ua tib yam rau 50k ib, tab sis lub sijhawm no lub davhlau ya nyob twg nruab nrab yuav mus rau A1 tus pin ntawm Arduino.
Tam sim no peb tau sib dhos cov pob qhov rooj peb yuav sib sau ua ke ib feem ntawm lub Circuit Court uas suav nrog FM transmitter. Coj tus module thiab saib cov pins. Koj yuav tsum pom Vcc lub davhlau ya nyob twg, Cov av hauv av, tus pin SDA thiab tus lej SCL. Nws yuav tsum pom tseeb tias Vcc mus rau 5V, thiab Av mus rau GND. Tam sim no rau SDA thiab SCL, koj yuav tsum tau saib mus rau ntu txuas rau Arduino ntawm koj xaiv, tshwj xeeb tshaj yog saib rau I2C ib qho. Txog rau arduino Nano, SDA nyob hauv tus pin A4 thiab SCL hauv tus pin A5, yog li txuas mus txuas rau txhua tus pin thiab koj yuav tau sib sau ua ke ib feem kis tau tus mob.
Ntxiv mus, peb yuav txuas tus tes hloov qhov. Qhov kev hloov pauv ua haujlwm hloov pauv ntawm cov xeev los khaws cov zaus uas peb xav xa thiab teeb tsa zaus uas peb yuav xav xa mus. Kev sib txuas ntawm qhov hloov pauv yog yooj yim zoo nkauj, yooj yim txuas rau ntawm lub davhlau ya nyob twg tus tiv thaiv uas yuav mus rau qhov chaw, thiab tom qab ntawd txuas mus rau tib lub davhlau ya nyob twg luv rau Arduino tus pin D9 txhawm rau txhawm rau tuaj yeem saib rau kev hloov pauv hauv lub neej yav tom ntej. Lub davhlau ya nyob twg thib ob yuav mus rau hauv av.
Thaum kawg, muaj ntau cov lus qhia rau txuas LCD rau Arduino, yog vim li cas kuv yuav tsis piav qhia yuav ua li cas. Txawm li cas los xij, Kuv yuav suav nrog qhov txuas uas kuv siv rau kev txuas hais tias LCD tsis muaj tus tsav tsheb.
Txuas:

Qhov txuas yog lus Mev, tab sis kev piav qhia txaus rau txhua tus neeg uas tsis hais lus.
Ib qho ntxiv, Kuv xav txog qhov muaj txiaj ntsig zoo saib ntawm ob qho tib si uas suav nrog hauv ntu no.
Kauj Ruam 3: Txoj Cai
Thawj qhov koj yuav pom yog suav nrog lub tsev qiv ntawv npe hu ua FMTX.h Nov yog lub tsev qiv ntawv tsim los ntawm Elechouse rau kev siv lawv tus kheej cov qauv. Koj tuaj yeem nrhiav lub tsev qiv ntawv no thiab cov ntaub ntawv ntau ntxiv txog kev siv cov qauv no hauv cov ntawv teev tseg, uas koj yuav pom hauv qhov txuas hauv qab no:
www.elechouse.com/elechouse/index.php?main_…
Tam sim no txoj cai siv lub hauv paus ntawm digital electronics nce flank. Daim duab hloov pauv txuas nrog rau qhov chaw thiab LED. Intuitively koj yuav pom tias yog tias koj thawb lub pob LED yuav qhib, thiab yog tias koj tso mus, LED yuav tua. Tam sim no, lub tswv yim yog ua kom LED nyob rau thawj qhov thawb ntawm lub pob thiab rau qhov tshwm sim ib qho, LED yuav tig ntawm. Peb yuav siv tib txoj cai rau peb cov cai. Thawj lub xeev yuav yog rau teeb tsa zaus uas peb yuav xav xa thiab thib ob rau kev txuag. Txog kev kis ntawm qhov zaus ntawd koj yuav muaj o rov qab mus rau thawj lub xeev.
