Nyob zoo sawv daws, Hauv qhov haujlwm no kuv yuav qhia koj li cas kuv tau ua lub tshuab PWM qis heev nrog cov khoom siv tsawg heev.
Qhov kev hloov pauv no nyob ib ncig ntawm schmitt ua rau lub voj voog.
Raws li qhov yuav tsum tau ua, Kuv tau cais 3 hom kev sib txuas hauv 3 theem sib txawv.
Qhov no tuaj yeem ua tiav lub luag haujlwm ua haujlwm siab txog li 150-200 vib nas this!
Kauj ruam 1: Yees duab
Kuv tau ntxiv cov vis dis aus ntawm qhov haujlwm no hauv youtube, vam tias koj nyiam cov vis dis aus no thiab vam tias nws yuav pab tau.
Kauj Ruam 2: 50% Duty Cycle, Hloov pauv zaus
Cov khoom siv xav tau yog-
1 LM358 ib
1 DIP8 ic qhov (socket)
1 10k potentiometer
1 daim ntawv
3 20k resistors.
1470uF electrolytic capacitor.
solder, chaw nres tsheb laug, txuas txuas hlau thiab lwm yam
Lub voj voog no yuav xa cov xwm txheej yoj nrog 50% kev ua haujlwm tsis tu ncua. lwm qhov txiaj ntsig zoo ntawm qhov kev sib tham no yog qhov kev xav, qhov zaus yuav tsis hloov txawm tias hloov pauv qhov hluav taws xob. Qhov no yog qhov txiaj ntsig zoo hauv kev piv rau ib txwm 555 timer ic uas nws qhov zaus yog qhov hluav taws xob ntau.
Ntawm no, thaum lub zog siv hluav taws xob, lub capacitor yuav pib them los ntawm tus tiv thaiv R. Thaum nws mus txog qhov teeb tsa teeb tsa, lub capacitor pib tso tawm los ntawm tib tus tiv thaiv kom txog thaum nws mus txog qis dua. Qhov no mus rau suav tsis txheeb.
Qhov zaus ntawm PWM yuav nyob ze rau lub sijhawm tas li ntawm RC Circuit uas yog RxC
Siv 10 tig lub tshuab txiav kom tswj tau qhov zoo dua.
Kauj Ruam 3: Zaus Zaus thiab Cov Cuam Tshuam Lub Luag Haujlwm
Cheebtsam-
Lwj 358
DIP8 qhov (socket)
470uF electrolytic capacitor
1 N007 Diode x2
10k 10 tig trimmer
perfboard.
20k3x wb
Ntawm no, lub capacitor pib them los ntawm ib nrab ntawm lub zog thiab pib tso tawm los ntawm lwm qhov ib nrab ntawm tus tiv thaiv. Qhov no txhais tau tias, rau tag nrho cov voj voog, ua tiav ib feem ntawm lub zog ntsuas.
Ntawm no, lub sijhawm PWM yuav kwv yees li sib npaug rau R x C qhov R yog tus nqi tag nrho ntawm lub hwj chim.
Kauj Ruam 4: Kev Ywj Pheej Rau-Tawm Sijhawm Sijhawm
Cheebtsam-
LWM 358
DIP8 qhov (socket)
470uF capacito2 diodes
2 10k tus kws txiav plaub hau
perfborard
Lub voj voog no tuaj yeem siv los tswj lub zog kom siv hluav taws xob qis heev xws li kev ua vaj zaub lossis qee qhov haujlwm uas yuav tsum tau siv lub roj teeb. Qhov no txhais tau tias, lub roj teeb lub zog tsuas yog siv thaum lub Circuit qhib thiab tsis yog thaum cov zis qis.
Kuv tus kheej siv qhov kev ntsuas no los tswj hwm esp32 uas siv 80mA txuas mus tas li rau ntau dua 3 hnub!
Qhov no tau ua tiav los ntawm kev ua kom lub ntsej muag nyob ntev li 5 vib nas this thiab qis rau 150 vib nas this.

Tsawg Yam Tsawg - Arduino ntawm Breadboard: Arduino siv ATMega328p nti. Peb tuaj yeem tau txais qhov ntawd hauv SMD hom ntawv (ATMega328p-AU) lossis DIP hom rau lub qhov dej sib txuas (ATMega328p-PU). Tab sis, nti los ntawm nws tus kheej tsis tuaj yeem ua haujlwm. Nws xav tau ob peb yam ntxiv thiab txhua qhov ua ke hu ua liab qab
