Video: 555 Monostable ntawm Ncua Sijhawm: 3 Kauj Ruam
2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:29
Lub 555 Timer tuaj yeem siv tau hauv ob peb hom sib txawv.
en.wikipedia.org/wiki/555_timer_IC
Ntawm no peb yuav siv nws hauv Monostable (tsim cov mem tes tso zis) teeb tsa.
Nov yog qhov txuas txuas tau ntawm qee cov peev txheej zoo rau kev nkag siab 555 Timer.

Kauj Ruam 1: Lub Sijhawm Suav
Rau kuv qhov project kuv xav tau ncua ntawm kwv yees li 3 Thib Ob.
Kev suav rau lub sijhawm yog t = 1.1 * R (Resistance in ohms) * C (Capacitance in Farads)
Hauv kuv qhov Circuit kuv muaj 3M ohm resistor thiab 1 micro Farad capacitor.
Qhov ntawd yog 3000000 Ohms thiab 0.000001 Farads
yog li lub sij hawm (t) = 1.1 * 3000000 * 0.000001
t = 3.3 vib nas this
Nov yog lub laij lej yooj yim
Kauj Ruam 2: Puv Circuit Court
Nov yog daim phiaj xwm txheej puv ntoob.
Hauv Circuit no muaj ob qhov xa tawm, ib qho yog tsav los ntawm kev tawm tswv yim sab nraud uas tom qab ntawd ua rau lub teeb liab ua rau lwm qhov yog tsav los ntawm 555 lub sijhawm. Thaum cov tswv yim mus siab qhov kev xa xov hluav taws xob qhib thaum lub teeb liab nkag mus tawm muaj 3.3 Qhov thib ob ncua ua ntej qhov kev xa tawm tawm.
Kauj Ruam 3: PCB Txheej Txheem
Nov yog PCB txheej txheem no tuaj yeem xa mus rau PCB qhov kev pabcuam xws li www. OSHPark.com
