Siv DFRobot's UART ntiv tes ntsuas kom khaws cov ntiv tes thiab tsuas yog tso cai rau cov neeg nkag mus rau lub npov.

Kauj ruam 1: Tswv yim

Txawm hais tias nws yog qee tus nosy nus muag lossis ib tus phooj ywg uas tsis nyob ntawm koj cov khoom, muaj peev xwm khaws cov khoom ruaj ntseg thiab tom qab ntawd siv cov lej ntsuas los qhib lawv yog lub tswv yim zoo.

Txog qhov haujlwm no, DFRobot tau hu rau kuv thiab muab kuv lawv UART Fingerprint Reader rau kuv.

Qhov xav tau:

  • DFRobot Fingerprint Sensor -
  • DFRobot Particle Photon -
  • 5 hli LED x 2

Txoj hlua rau txoj haujlwm no yooj yim heev. Ua ntej, tus ntiv tes ntsuas yuav tsum tau txuas nrog Photon ntawm nws UART pins. Cov xov hlau dawb mus rau Tx thiab ntsuab txuas mus rau Rx. Tom ntej no, ob lub LED tau txuas nrog tus pin 2 thiab 3, nrog rau lawv thaj chaw.

Kauj ruam 3: Sau npe

Txhawm rau kom ntiv tes kom raug lees paub, nws yuav tsum xub sau npe. Qhov no khaws cov duab hauv lub cim xeeb tso rau sab hauv. Txhawm rau ua qhov ntawd, Kuv tau rub daim ntawv sau npe.ino kos rau ntawm Particle Cloud IDE thiab xa nws mus rau Photon.

Tom ntej no, Kuv tau qhib lub ntsuas saib thiab rov pib dua Photon, qhov uas kuv tso thiab tshem kuv tus ntiv tes ob peb zaug ntawm lub ntsuas, thiab qhov twg kuv tau hais kom txuag nws nrog tus lej ID.

Tam sim no tias kuv tus ntiv tes tau raug khaws cia, Kuv tau rub daim duab txuas thiab rub nws. Nws tshuaj xyuas tas li yog tias tau muab ntiv tes tso, thiab yog tias nws muaj, nyeem nws.

Tom ntej no, nws sim paub qhov luam tawm thiab ID nws. Yog tias nws phim tus ID raug, lub teeb hloov mus rau ntsuab thiab lub thawv qhib.
