Yuav luag txhua qhov haujlwm uas kuv tau ua hauv kuv lub neej siv arduino lossis tsuas yog atmegas, tab sis zaum kawg ntawm kev qhia hluav taws xob hauv kuv lub tsev kawm ntawv kuv pom cov kev sib txuas me me hu ua 555. Kuv tau hnov txog nws ua ntej tab sis kuv tau xav tias microcontrollers zoo dua. Kuv tau nyeem qee yam txog 555 hauv is taws nem thiab kuv pom tias qhov no yog qhov kev sib txuas zoo tshaj plaws hauv ntiaj teb! Thiab kuv yeej tsis tau siv nws: (Kuv xav tias nws tuaj yeem ua tau zoo los ua ib yam dab tsi kiag li yam tsis muaj programing thiab tsuas yog nrog cov khoom siv hluav taws xob yooj yim. Kuv pib xav tias kuv tuaj yeem ua dab tsi nrog 555, tab sis tsis tuaj yeem pom dab tsi txaus siab dua li kuv tham nrog kuv tus phooj ywg txog cov tshuab siv tsis tau thiab kuv xav tias kuv tuaj yeem ua lub tshuab tsis siv nrog 555, servo, qee qhov tiv thaiv thiab hloov. Thiab nws yuav yooj yim heev thiab kuv tsis xav tau microcontroller los ua nws! Kuv xaj qee yam 555 hauv internet thiab xav tias kuv tuaj yeem sim kuv qhov kev tsim hauv qee qhov kev sim. Hauv tsev kawm ntawv peb siv electrosym tab sis nws laus heev thiab kuv tsis nyiam nws. Tab sis kuv tau nyeem txog circuits.io thiab kuv xav tias kuv yuav sim nws, tom qab kuaj txhua yam kuv ua tau hais tias qhov program no zoo nkauj heev los pib nrog, nws yooj yim siv thiab siv tau yooj yim heev.

Dab tsi yog lub tshuab tsis siv? Nws yog lub tshuab uas tsis muaj dab tsi ua, nws tsuas yog ua rau qhov tsis muaj txiaj ntsig. Zoo li switching off switch:)

Kauj Ruam 1: Qhov Chaw

- 555 timer Kuv xav tias koj tuaj yeem yuav nws hauv txhua lub khw hluav taws xob, qhov no yog lub taub hau ntawm peb lub tshuab tsis siv

- Servo, qhov nrov tshaj plaws micro servo koj tuaj yeem pom nws hauv RC khw lossis khoom siv hluav taws xob, nws yuav hloov peb qhov hloov pauv

- Qib hloov, nws yog qhov tseem ceeb vim tias peb yuav hloov nws nrog servo yog li nws tsis tuaj yeem yog lwm hom kev hloov pauv

- resistors, Kuv yuav qhia koj qhov tseem ceeb hauv cov kauj ruam tom ntej

capacitor 100 nF

- diode (tsis yog LED, rectifier diode)

- roj teeb (1 cell lipo, lossis 2 AA roj teeb)

Kauj Ruam 2: Qee Lej

Ntawm cov duab saum toj no koj pom yuav ua li cas kuv xam qhov muaj nuj nqis resistors. Kuv siv 2 teev los xam cov txiaj ntsig rau cov neeg tawm tsam thiab txhua lub sijhawm kuv tau rho tawm qhov tsis kam uas ua tsis tau Kuv tsis paub tias qhov twg tsis yog. Hnub tom qab tom qab zoo li teev tshawb hauv google Kuv pom tias yog lub xeev siab dua luv dua peb yuav tsum ntxiv cov diode thiab hloov cov qauv me ntsis:)

Servo yog tswj nrog 50Hz PWM teeb liab, yog tias peb teeb tsa lub teeb liab siab hauv qhov pwm no rau 1.5ms servo yuav mus rau 90 degrees, yog tias koj teeb 2ms nws yuav mus rau 180 thiab 1ms txog 0 degrees. Yog li thaum hloov tawm qhov teeb liab siab Kuv tau txais 1ms thiab qis dua teeb liab 19ms ua ke nws yog 20ms (0.02s) kom tau txais qhov zaus koj xav tau faib 1/0.02 = 50Hz. Thaum hloov tau qhib kuv tsuas yog hloov lub teeb liab mus rau 2ms thiab qis rau 18ms. Kuv vam tias koj nkag siab nws:) yog tias koj xav paub ntau ntxiv, google 555 thiab koj yuav tsum pom ntau cov lus qhia zoo txog nws.

Kauj Ruam 3: Simulation

Thaum kuv tos rau kuv ntu kuv pib simulating kuv tus qauv hauv circuits.io. Nws mus tau zoo heev thiab txhua yam ua haujlwm. BTW circuits.io yog qhov haujlwm zoo nws qhia koj tias servo txav mus los lossis yog tias koj muab lub zog loj rau LED. Hauv kuv qhov Circuit kuv ntxiv oscilloscope kom pom lub teeb liab thaum sim nrog cov tiv thaiv. Nov yog qhov txuas rau mys tsim yog tias koj xav tshuaj xyuas nws:

circuits.io/circuits/3227397-555-useless-machine

Kauj ruam 4: Scheme

Nov yog cov phiaj xwm los ntawm circuits.io thiab dav dawb hau (Kuv tau ua lub dav dav dav dav los ua ib lub PCB rau nws, thaum sau cov lus qhia no kuv pom kev xa tawm mus rau kev xaiv dav dawb hau hauv kev sib tw:)) Hauv qab no koj tuaj yeem pom cov khoom tiv thaiv, lawv yog me ntsis txawv dua li suav vim tias tsis muaj qhov ua kom raug qhov tseeb, Nws yog qhov ua tau uas koj yuav tsum sim nrog cov khoom tiv thaiv kom tau txais nws ua haujlwm vim tias cov resistors tsis zoo tag nrho thiab muaj 5% kam rau ua tus nqi.

C1 = 100 nF

R1 = 100000

R2 = 0

R3 = 247,000

R4 = 16400

Kauj ruam 5: 3D Cov Ntaub Ntawv

Rau kuv lub tshuab siv tsis tau kuv tau ua 3D luam ntawv. Yog tias koj xav tau koj tuaj yeem ua nws tawm ntawm ntoo (nws yuav zoo dua li qhov zoo dua) hmoov tsis kuv tsis muaj txuj ci hauv tes ua tej yam, yog li kuv tsuas yog tsim thiab luam tawm nws.

Kauj Ruam 6: Sib dhos

Pib nrog kev sib dhos nrov plig plawg nrog sab saum toj, yog qhov no koj yuav tsum tau siv daim kab xev (txoj kab uas hla ntawm 1.75) lossis qee yam zoo sib xws. Tom qab ntawd rau saum koj tuaj yeem ntsia hlau ntawm micro servo thiab hloov pauv. Rau cov ntsia hlau servo koj yuav tsum siv M2 screws tsawg kawg 8mm ntev. Txhawm rau ntswj caj npab koj yuav tsum siv dua M2 ntsia hlau thiab ntsia hlau rau ntawm qhov muaj zog heev.

Kauj Ruam 7: PCB

Kuv kuj tau ua PCB rau kuv lub tshuab, Kuv nyiam ua PCBs, yog tias koj tsis yog siv nws li ib txhais ceg lossis ib yam uas kuv tsis paub yuav hais nws li cas, tsuas yog tsis muaj PCB: D Qhov no yog kuv thawj milled PCB, hloov ntawm thermotransfer methodod Kuv txiav txim siab zeb nws nrog lub tshuab CNC me me. Thiab tsawg kawg rau PCB no txoj hauv kev no zoo dua vim tias koj tsis tas yuav cuam tshuam nrog ironing nws thiab siv cov kua qaub. Tab sis kuv paub tias milling cov kab me me thiab cov ntaub qhwv rau SMD sib xyaw tuaj yeem ua tsis tau.

Kauj ruam 8: Txaus siab rau nws

Tam sim no koj tuaj yeem siv lub tshuab super no los ua qee yam muaj tswv yim, hloov lub ntiaj teb, lossis tsis yog, qhov no tsuas yog qhov tsis muaj txiaj ntsig uas tua nws tus kheej. Tab sis kuv tau kawm ntau yam thaum tsim nws yog li tej zaum nws yuav tsis muaj txiaj ntsig? Thiab tsis txhob hnov qab muaj pes tsawg lom zem nws tuaj yeem muab rau koj: D Tsaug rau kev nyeem ntawv!
