Video: RFID Arduino Uno Relay Hloov, Nrog I2C Zaub: 4 Cov Kauj Ruam
2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:24
Nyob zoo, qhov no yog kuv thawj qhov haujlwm, kuv lub npe yog Oskar thiab kuv yog 13. Txoj haujlwm no ua haujlwm nrog I2C zaub, tsis yog ib qho zoo li qub
Kauj Ruam 1: Sau Cov Khoom Uas Xav Tau
Rau qhov haujlwm no, koj yuav xav tau:
-Arduino Ib
-I2C Zaub (Tsis xav tau tiag tiag, tab sis nws zoo dua nrog nws)
-Reelay
-MFRC522 RFID nyeem ntawv
-RFID Cards / NFC qhib lub xov tooj
Kauj ruam 2: Kev sib txuas
Txhua qhov kev sib txuas:
I2C zaub:
GND, VCC mus rau Arduino GND thiab 5V
SDA mus rau tus pin A4
SCL mus rau tus pin A5
RFID nyeem ntawv:
SDA pin 10
SCK to pin 13
MOSI to pin 11
MISO to pin 12
IRQ tsis txuas nrog txhua qhov chaw
GND rau Arduino GND
RST tsis txuas nrog txhua qhov chaw
3.3V rau 3.3V tus pin ntawm Arduino
Tshaj tawm:
"-" mus rau GND
"+" mus rau Arduino 5V tus pin
S mus rau tus pin 7
Tias 's tag nrho
Kauj ruam 3: Code
Rau txhua qhov no ua haujlwm, Kuv suav nrog cov cai siv los ua txoj haujlwm no.
Lus Askiv version:
Qhov no yog.ino cov ntaub ntawv, txhais tau tias yuav qhib nrog Arduino IDE
Kauj ruam 4: Nws yog
Koj tau ua tiav, tam sim no kuv yuav sau qee qhov kev siv nthuav rau qhov no:
RFID Lub teeb hloov
RFID Qhov rooj xauv
RFID Tsheb Killswitch
RFID Tswj Kev Nyab Xeeb
RFID tswj qhov hluav taws xob
