Cov lus qhia no yuav qhia koj yuav ua li cas thiaj tsim tau ntau lub platform nrog tus pas ntsuas kub, chronograph (suav txog timer), suav timer, thiab teeb pom kev. Nws kuj tseem npaj ua lub platform rau lwm cov khoom siv sib piv lossis lwm yam haujlwm uas koj tuaj yeem xav txog.

Txhawm rau tsim lub ntsuas cua digital koj yuav xav tau:

- Hlau - Altoids tin - Breadboard - Hloov pauv Resistor - Dual -digit Common Anode 7 Segment Display - 4 2N2222 Transistors - 2 220 k ohm Resistors - Thermistor (nyiam dua tso tawm tawm) - 2 Momentary Push Buttons - 2 2.2 k ohm Resistors - 5 volt Regulator - 2 Leveling Capacitors rau Cov Khoom Siv Hluav Taws Xob (Kuv siv 220 uF) - Hloov Lub Hwj Huam - ATMEGA168 Microcontroller - 16 MHz Crystal - 1 k ohm Resistor - Luam Luam Ntawv (Loj dua tom ntej ntawm Altoids tin) - Qhov (txhua yam koj xav tias koj xav tau) tej zaum yuav xav tau) Cov cuab yeej xav tau: - Soldering hlau - Desoldering Pump (yeem) - Wire Stripper (xaiv tau) - Hlau Cutters

Rau cov kauj ruam no, siv cov kab lus txuas (lo lus lossis AutoCAD) los tsim lub Circuit Court. Kuv ib txwm pom tias nws muaj txiaj ntsig zoo ua ntej tsim nws ntawm lub lauj kaub tais diav uas tsis txhuam. Qhov no ua rau nws yooj yim los kho txhua yam teeb meem uas tshwm sim ua ntej koj xav rub koj cov plaub hau tawm:)

Ua ntej koj pib soldering nws yog qhov zoo tshaj plaws ua ntej txiav lub khob cij rau qhov loj me thiab npaj txhua qhov loj ntawm lub rooj tsavxwm (raws li pom hauv daim duab thib ob hauv qab no). Tsis txhob hnov qab tso cai rau chav rau cov nyees khawm saum lub rooj tsavxwm thiab khawm lub zog tawm mus rau sab. Nws yuav tsum raug sau tseg tias hauv qhov txheej txheem uas R5 yog qhov sib piv tiv thaiv rau cov thermistor, thiab nws yuav suav nrog hauv koj lub thermistor, yog li koj yuav tsum txheeb xyuas koj cov ntawv ntawv seb yuav siv koj li thermistor tshwj xeeb li cas.

Txhawm rau ntsuas lub ntsuas cua, koj yuav tsum tau nyeem los ntawm lub microcontroller ntawm qhov kub sib txawv (ntau qhov zoo dua).

Kuv tau txuas cov ntawv hex kom thauj mus rau lub microcontroller's flash kom pom cov lus sib piv los ntawm cov thermistor. Yog tias nws nyeem nrog kab hauv qhov tso tawm, nws yog vim lub thermistor cov tswv yim siab dhau los ua kom pom ntawm ob tus lej (piv txwv li cov zis -5 tuaj yeem yog 155 txog 105). Cov ntsiab lus yuav tsum tau npaj ua ntej hauv Excel raws li cov phiaj xwm tawg, tsis txuas nrog kab (piv txwv li pom kuv qhov ntsuas kub tau nyeem hauv qab no). Tom qab ntawd koj yuav tsum nyem txoj cai cov ntsiab lus ntawm kab ntawv thiab nyem "Ntxiv Trendline". Tom ntej no xaiv hom kev ua zauv uas ze tshaj plaws rau kab pom uas tsim los ntawm cov qauv piv txwv (Kuv siv kab zauv tawm vim tias kuv lub thermistor tau ua kom muaj cov kab tawm). Tom ntej no nyem rau qhov "xaiv" tab thiab xaiv "zaub sib npaug ntawm daim duab" thiab nyem OK. Qhov sib npaug no yuav tsum tau nkag rau hauv qhov chaw ntawm cov mis hauv qhov chaws, qhov twg x yog "analogRead (tempPin)". Qhov chaw ua qhov no tau qhia hauv qhov chaws (pom hauv cov lus qhia). Tus kws kho kuv siv rau qhov chaws yog Arduino 0007. Qhov kev zov me nyuam kuj tseem tsim cov hex cov ntaub ntawv hauv applet sub nplaub tshev ntawm txoj haujlwm thaum koj nyem lub pob sau ua ke hauv qhov program. Cov ntawv hex no tuaj yeem thauj mus rau hauv lub flash ntawm lub microcontroller siv txhua txoj hauv kev (xws li AVRIsp mkII).

Txhawm rau Npaj rooj plaub los tuav cov khoom siv hluav taws xob, ob yam yuav tsum tau ua.

Thawj yog txiav lub qhov rau LED zaub, sib txawv resistor, ob lub sijhawm thawb lub khawm thiab lub zog hloov. Kuv tau ua qhov no los ntawm thawj zaug tso cov khoom siv hluav taws xob ua tiav rau hauv cov tin. Tom ntej no, khaws cov tin hauv qhov chaw zoo ib yam, Kuv tau siv lub laser ua cov lus qhia txhawm rau kos cov npoo ntawm ib sab, tom qab ntawd kaw lub hau, khawb raws txoj kab laser cim rau qhov txiav. Tom qab ntawd kuv tau laum tawm ib lub ces kaum (xws li lub qhov tso saib). Thaum kawg, Kuv siv rab riam ntse los txiav ua kab. Tsis txhob txhawj xeeb txog kev hloov cov hlau ib puag ncig ntau dhau, nws tuaj yeem ua kom yooj yim tom qab los ntawm kev muab cov ntoo thaiv hauv qab ib sab, thiab tsoo lub ntug me ntsis nrog rauj. Qhov thib ob uas yuav tsum tau ua yog kab hauv qab nrog cov duab los qhia (nyiam dua nyias) txhawm rau tiv thaiv cov khoom siv hluav taws xob los ntawm luv luv ntawm cov hlau hauv qab. Qhov no ua tau yooj yim los ntawm nias Altoids rooj plaub ntawm daim duab los ces nws tawm qhov kev nyuaj siab raws ntug. Tam sim no tsuas yog txiav raws qhov kev nyuaj siab thiab ntxig rau hauv qab ntawm cov tin (saib daim duab lo).

Kuv tsim daim ntawv lo los ntawm rub tus qauv rau cov ntawv luam tawm uas kuv yuav. Ntxiv mus yog ib qho nyuaj tshaj plaws rau kuv, ua qhov tsim nyog saib. Kuv siv cov duab kos thiab cov duab yooj yim los tsim nws. Kuv tau txuas cov qauv tsim kom koj tuaj yeem siv lossis hloov kho nws. Ntawm no, luam tawm nws thiab txiav raws cov kab sab nrauv (nco ntsoov tias koj txiav cov kab ntawv dub tawm ntawm txoj cai). Tam sim no muab daim ntawv lo. Kuv pom nws muaj txiaj ntsig los tuav nws mus rau lub teeb thaum ua qhov no, nws pab pom qhov twg yog qhov rau kab nws. Thaum kawg, txiav kab kab pheeb ces kaum hla lub qhov thiab quav cov flaps hauv qab (saib daim duab hauv qab no) thiab ua tiav txhim kho cov nyees khawm.)
