Kuv Qhov Kaum Yam Tseem Ceeb Tshaj Plaws Cov Lus Qhia thiab cov lus qhia: 9 Kauj Ruam (nrog Duab)

2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:31

Muaj 6 ntiv tes los daus hauv av, thiab koj tau koom nrog hauv tsev. Koj tau poob ib ntus koj qhov kev mob siab rau ua haujlwm ntawm koj li GPS-coj ua hlau txiav laser. Tsis tau muaj ib qhov haujlwm tshiab ntawm koj qhov chaw koj nyiam uas tau ua rau koj nyiam. Yuav ua li cas nrog koj tus kheej?

Zoo, yuav ua li cas pimping li koj lub khob cij thiab tig nws mus rau hauv kev ntshuam, txhais tau tias, kev tsim kho tshuab digital? Nov yog cov npe luv ntawm cov txiaj ntsig tau txiaj ntsig tshaj plaws uas kuv tau khaws ntau xyoo. Vam tias muaj qee yam nyob ntawm no uas koj yuav pom muaj txiaj ntsig uas koj tsis tau xav txog. Ok, kuv tsis tshua muaj 10 lub tswv yim los qhia; nws tsuas yog ua rau lub npe zoo dua.: P

Kauj Ruam 1: Txuas Hluav Taws Xob

Zoo, thawj qhov uas lub khob cij xav tau yog lub zog. Muaj ntau daim ntawv qhia zaub mov tuaj nrog kab ntawv sib dhos. Qhov no zoo yog tias koj mob siab siv lawv. Tab sis koj tseem yuav tsum ntsaws cov xov hlau rau hauv lub rooj tsavxwm. Kuv tau cuam tshuam qhov no qee zaum, sib xyaw lub zog thiab cov xov hlau hauv av. Txawm hais tias tsis tshua muaj, qhov no feem ntau ua rau muaj kev thab plaub thiab/lossis raug txim kim. Kev daws kuv tuaj nrog yog ib txwm siv 3-tus pin txuas. Saib daim duab hauv qab no. Nws tau tsim los ntawm SIP header pins thiab protoboard. Tom qab taw tes-rau-taw tes thaiv, nws tau npog nrog cov duab puab epoxy.

Kauj Ruam 2: Fais Fab thiab Tsheb Npav

Muaj qee lub sijhawm nws yuav muaj txiaj ntsig zoo rau kev txiav txim siab qee lub zog thiab cov tsheb hauv av rau qhov sib txawv ntawm qhov hluav taws xob. Rau kuv, lub sijhawm no tseem tsis tau tshwm sim. Kuv txiav txim siab txuas lawv mus tas li txhawm rau txo qee qhov kev sib tsoo. Koj txhua yam koj yuav tsum ua yog ntswj lub khob cij los ntawm sab nraub qaum, yog tias nws muaj. Tom qab ntawd txiav tawm ib txoj hlua ntawm ua npuas ncauj thaub qab nrog rab riam Exacto. Tom ntej no, muab lub zog hluav taws xob thiab tsheb npav hauv av nrog qee cov xaim zoo. Tom qab ntawd npog nrog kab xev thiab ntsia hlau rov qab mus rau tom qab.

Kauj ruam 3: LED

LEDs feem ntau siv hauv kev debugging/kev txhim kho ntawm feem ntau ntawm cov khoom siv hluav taws xob.

Zoo, cov khoom noj khoom haus-phooj ywg LED's tsis yooj yim los ua raws li khoov ib ncig ntawm ib qho, tab sis lawv siv tsis tau tas mus li thiab yuav txuag koj ntau qhov chaw ntawm koj lub khob cij. Vim tias lawv muaj tus tiv thaiv tam sim no txwv tsis pub sib txuas thiab cov hlau lead sib nrug yog 0.4 ", lawv ntsaws ncaj qha nruab nrab ntawm koj lub zog/tsheb nqaj hlau hauv av thiab ntu tseem ceeb ntawm daim ntawv qhia zaub mov. Thiab txawm tias zoo dua, lawv tuaj yeem muab sib dhos ib sab. siv 0.03 "tuab ib sab pcb, 3mm LED's, 240R nto mount resistors, thiab SIP header pins los ua cov no. Qhov ua kom yuam kev tsuas yog tso cov pins hauv lub taub hau kom txog thaum tom qab koj tau muab lawv pov tseg, txhawm rau khaws cia qhov sib nrug. Thiab kom lawv tau teeb tsa ib sab-sab-ib sab, Kuv tsau ob sab ntawm LED me ntsis nrog Dremel. Nov yog daim vis dis aus qhia seb kuv ua lawv li cas: https://s18.photobucket.com/albums/b103/klee27x/Published/? Action = view & current = LED_BreadOut.mp4

Kauj ruam 4: Nyees khawm

Cov nyees khawm, cov nyees khawm, nyob txhua qhov chaw. Ntawm qhov 6mm tactile hloov yog lwm daim ntawv qhia zaub mov. Thaum koj xav tau tsuas yog 1 lossis 2, koj tsuas tuaj yeem lo lawv rau hauv daim ntawv lo. Tab sis sim siv ntau dua qhov ntawd, thiab koj yuav sai sai no muaj cov nyees khawm tawm ntawm lawv tus kheej thoob plaws qhov chaw, ntxiv rau kev loj hlob cov phaj zoo ntawm spaghetti. nkag tus pin rau hauv av tsheb nqaj hlau lossis tsheb nqaj hlau fais fab. Los ntawm kev ua lub pob khawm, koj tuaj yeem ntsaws hauv av/lub tsheb ciav hlau ib zaug xwb, thiab tseem yuav muaj qhov ntom ntom ntau dua ntawm cov nyees khawm uas yuav tsis poob tawm. Koj tuaj yeem ua rau koj lub pob khawm nce mus txog 3 khawm sib sib zog nqus thiab tseem siv tib tus lej ntawm lub qhov rooj hauv lub khob cij … tab sis kuv pom 2 kab ntawv kom yooj yim dua.

Kauj ruam 5: Hloov

Qee zaum nws muaj txiaj ntsig kom muaj qhov hloov pauv me me es tsis yog khawm-rau-ua khawm. Feem ntau cov hloov pauv yuav tsis haum rau hauv daim ntawv qhia zaub mov. DIP hloov kab sib dhos haum zoo thiab tseem tshwm sim kom muaj 0.3 "los ntawm 0.1" sib nrug. Zoo heev!

Kauj Ruam 6: Pullup Resistors

Txhua tus neeg cuam tshuam nrog cov khoom siv hluav taws xob yuav paub zoo nrog rub tawm/nqis resistors. Nws tsis yog qhov phem nyob rau hauv cov hnub qub zoo thaum 1/4 watt resistors muaj cov khoom khov kho zoo rau lawv. Vim yog qhov xav tau ntau ntxiv rau tooj liab, cov khoom no tam sim no tau ua nrog cov yuag yuag uas tsis tuav kom rov siv tau zoo ib yam li lawv tau siv rau. Qhov kev tiv thaiv rub tawm no tau ua tib yam li cov LED thiab yuav kav mus ib txhis. zoo kom muaj qee qhov 10k bussed network resistors ntawm tes, rau thaum koj xav tau rub tag nrho kab ntawm IC pins lossis cov nyees khawm!

Kauj Ruam 7: Rau Kuv Cov Phooj Ywg PIC-hau: Breadboard Nrog Ua Hauv ICSP

Microcontrollers tau koom nrog hauv kev loj hlob ntawm DIY cov haujlwm. Thaum lub sijhawm txheej txheem txhim kho, nti yuav tsum tau rov tsim dua ntau zaus.

Kuv tsis paub yog tias tib yam siv rau AVR's, tab sis feem ntau txhua 8 thiab 14-pin PIC (ntxiv rau ntau ntawm 20 tus pin) sib koom tib lub pinout rau cov kab lus programming. Yog li kuv tau mob siab rau lub khob cij rau kev txhim kho ntawm PIC's no. Cov txheej txheem ntawm no yog tib yam uas tau siv los txuas lub tsheb npav fais fab/hauv av. Tom qab tev tawm qee qhov ntawm nraub qaum, koj tuaj yeem txuas xov tooj mus rau koj qhov kev sib txuas ua ke thiab xa lawv tawm mus rau tus qauv lub taub hau. Koj kuj tseem tuaj yeem txuas koj lub hwj chim thiab cov pins hauv av rau txoj kab uas tsim nyog thiab ntxiv cov nti nti thaum koj nyob ntawd. Koj tseem yuav pom qee qhov txuas ntxiv ntawm ib sab ntawm lub caj dab lub cajmeem. Zoo, tib tus pin uas tau siv rau ICSP kuj tseem tuaj yeem siv los ntawm micro raws li ib txwm siv/tso tawm pins lossis lwm yam haujlwm. Yog tias koj siv cov pins hauv koj txoj haujlwm, tom qab ntawd koj yuav tsum tau txuas/txuas koj lub xov tooj cua txuas txhua lub sijhawm koj hloov thiab hloov kho koj cov cai. Kuv tau pom, piv txwv li, tias tus PICKit2 programmer tuav cov kab lus kab lus qis thaum tus programmer tsis ua haujlwm. Ntau dua li tso nrog qhov no, Kuv tau txuas cov ntaub ntawv thiab kab kab dhau los ntawm cov teeb liab xa tawm uas tsuas yog kaw thaum tus programmer muab lub zog rau Vdd tsheb nqaj hlau. Lub hwj chim dhau los ntawm lub rectifier diode kom thaum tsuas yog siv lub zog sab nraud siv qhov txuas txuas qhib. Kab HVP tsis tau txais kev xa mus rau nws tus kheej. Hloov chaw nws tsuas yog kho qhov diode yooj yim, yog li thaum nws tsis ua haujlwm nws tsis rub MCLR kab qis. Kuj tseem muaj lub program programming khawm nyob rau sab laug sab laug ntawm lub rooj tsavxwm. Cov lus qhia yooj yooj yim no qhia kuv yuav ua li cas: https://www.instructables.com/id/PICKIT2-programming-button-mod/ *Kho kom raug: Txij li thaum tshaj tawm qhov no, Kuv tau raug ceeb toom thiab tseem tau lees paub tus kheej tias Vpp kab ntawm PICKit2 dhau los ua qhov tsis muaj kev tiv thaiv siab thaum tsis ua haujlwm, yog li nws tsis tas yuav tsum tau hloov kho diode rau kev sib cais hauv Circuit Court; txhua yam kuv tau ua tiav yog tshem tawm lub peev xwm ntawm tus programmer los kho lub khoos phis tawj ntawm MCLR kab (uas tsis tau cuam tshuam kuv txog tam sim no). Huag, zoo.. Kuv xav tau jumper rau kuv lub pcb, ib qho twg, thiab cov diode yog qhov loj me me.: P ** hloov tshiab: wow, tus txheej txheem ntawm moos/cais cov ntaub ntawv yog sooo xyoo tas los. Txheeb tawm daim duab tshiab kawg.

Kauj Ruam 8: ICSP Hat

Rau qhov tsis yog tus qauv pinouts, kev daws teeb meem yooj yim dua tuaj yeem xav tau ntau dua. Nov yog qhov yooj yim programming "lub kaus mom." Nws muaj 0.5 "kev sib nrug, yog li nws swb hla tus qauv nqaim DIP IC. Nws yog taw tes-rau-taw tes txuas, tom qab ntawd npog nrog cov duab puab epoxy. Tom qab ntawd tsuas yog ntsaws lub program cable thaum tsim nyog.

Kauj Ruam 9: Qhov Kawg

Zoo, yog nws Yog tias koj muaj lus qhia koj tuaj yeem qhia tawm, Kuv xav pom lawv!
