Yuav ua li cas thiaj li ua tau zoo L293D Tsav Tsheb
Yuav ua li cas thiaj li ua tau zoo L293D Tsav Tsheb

Tsis ntev los no kuv tab tom ua ib qhov haujlwm koom nrog stepper motors, thiab xav tau lub tshuab tsav tsheb uas muaj daim ntawv me me thiab muaj 4 qhov tso tawm. Tom qab ua tiav thiab kho kom zoo kuv tus qauv ntawm tus tsav tsheb no, Kuv txiav txim siab muab nws tso rau ntawm no, zoo li tsis muaj coob leej neeg tau ua qhov no. Tsis muaj adue ntxiv, ib tug freeform lub cev muaj zog tsav tsheb.

Koj tsis xav tau ntau los ua qhov no. Txhua yam koj xav tau yog: (1) L293D IC - Tus tsav tsheb. (1) Cov xov hlau me me-Nws tsuas yog xav tau txog 1 ntev. (1) Daim kab xev-12 txoj hlua, lossis ib qho 8-txoj hlua thiab ib qho 4-txoj hlua. -thwj tubing -Nws yeej tsis zoo kom muaj kev sib txuas luv. Koj tseem yuav xav tau cov tshuab txiav hlau, cov tshuab txiav, cov laug, thiab cov hlau txuas.

L293d muaj tus pinout zoo heev rau txhua yam tsuas yog PCB txheej txheem. Txij li plaub lub hauv paus pins nyob hauv nruab nrab, tsuas yog quav lawv kom txog thaum lawv tau kov tag nrho thiab tom qab ntawd muab tshuaj txhuam.

Kauj Ruam 3: Soldering Logic Power

Pin 16 yog Logic fais fab mov. Nws xav kom txuas nrog +5 volts. Pin 1 yog 1-2 channel pab tau. Nws yuav tsum txuas nrog +5 kom lub nti khiav. Kuv feem ntau txuas qhov ua rau +5, tab sis yog tias koj tsis xav vim koj xav siv lawv, tsuas yog hla cov kauj ruam no. Khaws cov pins 1 thiab 16 ua ke hla hauv qab ntawm lub nti, thiab cov laug.

Cuab yeej plaub txoj hlua ntawm kab rau cov pins nkag. Lawv yog: Tus Pin 2 Tus Pin 7 Tus Pin 10 Tus Pin 15 Cov cua sov ntswj hla qhov kev sib txuas.

Kauj Ruam 8: Cov Khoom Siv Solder thiab Ua Kom tiav

Tag nrho cov pins seem yog cov zis. Cov kab laug sab laug rau lawv. Koj tsis tas yuav ua kom sov lawv, vim txhua yam nyob ib puag ncig lawv yog insulated. Thiab qhov ntawd yog nws! Nqa nws mus rau lub cev muaj zog, nyob hauv qhov hluav taws xob thiab qhov txwv tam sim no, thiab muaj kev lom zem!
