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

Puv Circuit
Puv Circuit

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.
