Nco ntsoov ib txwm hnav tsom iav kev nyab xeeb!

Qhov no tsis yog txoj haujlwm kuv tau ua nrog kuv tus kheej.

nov yog cov khoom siv:

Kauj Ruam 1: Lub Hom Phiaj

Lub hom phiaj ntawm txoj haujlwm no yog kom cov tub ntxhais kawm kawm paub txog cov khoom siv hluav taws xob uas nws/nws yuav ua haujlwm nrog. Nrog rau kev coj ua kom zoo los txhim kho cov txuj ci tsim nyog.

Kauj Ruam 2: Txheeb Xyuas Qhov Chaw

Nco ntsoov tias koj muaj tag nrho koj cov khoom. (lub cim yuav pab koj nrhiav qhov chaw uas koj yuav muab koj cov khoom tso rau hauv daim ntawv luam tawm Circuit board)

- 100 ohm Resistor (1 / 4w) *kom muaj nuj nqis 4 / cim; R6 rau R9

- 1 K ohm Resistor (1/4) *kom muaj nuj nqis 1 / cim R5

- 74LS107 Integrated Circuit *kom muaj nuj nqis / cim IC1, IC2

- 8 Pin Qhov (Socket)

- Roj teeb Snap

- PC Board

Kauj ruam 3: Sib dhos

Txhua qhov kev sib txuas yuav ua tiav ntawm sab ntsuab ntawm PC Board. Solder ONE AT TIME, koj tuaj yeem siv daim kab xev xiav ntawm sab dawb ntawm PC Board los tiv thaiv koj cov khoom los ntawm kev ntog tawm.

Kauj Ruam 4: Kauj Ruam 1 - Resistors

TSWV YIM: Kuv pom zoo kom koj txiav cov xaim hluav taws xob ntau dhau tom qab txhua lub lauj kaub kom nws yooj yim dua rau cov laug.

1. ntxig thiab txhuam ib zaug, plaub 100 ohm, 1/4 W resistor hauv qhov chaw cim R6, R7, R8, R9

2. Ntxig thiab txhuam 10K, 1/4w resistor hauv qhov chaw cim R4

3. ntxig thiab solder 2.2K, 1/2w resistor hauv qhov chaw cim R1

4. ntxig thiab txhuam 330K, 1/4w resistor hauv qhov chaw cim R2

5. ntxig thiab txuas 1K, 1/4w resistor hauv qhov chaw cim R5

6. ntxig thiab solder 100, 1/2w resistor hauv qhov chaw cim R3

Kauj Ruam 5: Kauj Ruam 2 - Capacitors, Diodes thiab Transistor

TSWV YIM: Cov + txhuas mus rau hauv lub qhov cim " +" (sab ntev dua yog qhov zoo)

1. ntxig thiab txuas 1 uF capacitor hauv qhov chaw cim C1

2. ntxig thiab sib dhos.01 uF capacitor hauv qhov chaw cim C2

3. ntxig thiab txhuam PN2222 transistor hauv qhov chaw cim Q1

4. ntxig thiab txuas 1N4001 diode hauv qhov chaw cim D2. Nco ntsoov tias cathode nkag mus rau hauv lub qhov tsim nyog.

5. ntxig thiab txuas 1N4735 Zener diode hauv qhov chaw cim D1. Nco ntsoov tias cathode nkag mus rau hauv lub qhov tsim nyog.

Kauj Ruam 6: Kauj Ruam 6 - LEDs

1. Ntxig thiab txuas ob lub LED liab nyob hauv qhov chaw cim LED2, LED4. Nco ntsoov tias cov hlau lead ntev mus rau hauv lub qhov cim (+).

2. Ntxig thiab txuas ob lub LED ntsuab nyob hauv qhov chaw cim LED1, LED3. Nco ntsoov tias cov hlau lead ntev mus rau hauv lub qhov cim (+).

3. Yog tias koj tsis tau ua li ntawd, txiav tawm qhov ntev ntawm cov hlau lead ntau dhau.

Kauj Ruam 7: Kauj Ruam Kawg

1, ntxig thiab txuas ob lub 14-Pin IC qhov nyob hauv qhov chaw cim IC1 thiab IC2

2. ntxig thiab txuas ib qho 8-Pin IC qhov (socket) hauv qhov chaw cim IC3

3. ntxig thiab xaum dub cov hmoov lead ntawm lub roj teeb ntsaws rau hauv lub qhov cim "GND" thiab cov hlau lead liab rau hauv lub qhov cim "+9v"

4. ntxig ua tib zoo ob lub IC cim "74LS107" hauv cov cim cim IC1 thiab IC2. Qhov no yuav muab tso rau saum ob lub 14-Pin IC qhov (socket).

5. ntxig IC cim 555 hauv qhov (socket) "IC3" nrog kev qhia kom raug. Qhov no yuav yog qhov chaw nyob saum 8-Pin IC qhov (socket).

Kauj Ruam 8: Xeem

Siv daim duab los coj koj los ntawm cov txheej txheem ntsuas ua ntej txuas rau 9V Roj Teeb.
