Yog tias koj xav tau kev ywj pheej txhim kho koj lub khoos phis tawm nrog qee qhov "zoo nkauj", qhov yooj yim tshaj yog siv cov LEDs rau qhov no - lawv yooj yim siv, pheej yig thiab tsis tas yuav muaj kev txawj tshwj xeeb thiab tweaks. LED muaj peev xwm los kho koj qhov chaw ua haujlwm, muab teeb pom kev ntxiv, thiab tsuas yog zoo siab rau koj. Txhawm rau txuas LED, ua raws li peb qhia los ntawm kauj ruam cov lus qhia.
Tsim nyog
- 1. Qhov chaw ua haujlwm
- 2.qhov hlau thiab txhua yam koj xav tau ua haujlwm nrog nws
- 3.resistors uas yuav txo qhov voltage thiab tam sim no los ntawm lub zog fais fab
- 4. Txuas txuas nrog rau yuav tsum txuas LEDs rau lub khoos phis tawm
- 5.voltage tester
- 6.nippers kom cov hlua hlau
- 7. zom cov tubing
Cov Lus Qhia
Kauj ruam 1
Ua ntej pib ua haujlwm, nco ntsoov tias koj muaj tag nrho cov cuab yeej tsim nyog thiab cov khoom siv ntxiv rau txoj haujlwm.
Kauj ruam 2
Txuas mus rau 4-pin molex txuas Ua ntej saib peb yuav ua li cas txuas LED mus rau 4-pin molex txuas. Qhov no nws yog tus tsim kev ncaj ncees rau hauv lub khoos phis tawm, yog li nws muaj peev xwm ua tau tias koj lub khoos phis tawm muaj. Cov khoom txuas no muaj plaub pins: 1. +12 V (xaim daj)
2. + 5V (xaim liab)
3. Ob Tug Pins Hauv Pem Teb (Dub) Xaiv seb koj xav txuas cov diodes rau 12 lossis 5 volts. Yuav cov ntawv txuas lossis tshem tawm ntawm cov khoom qub tsis tsim nyog. Siv lub tshuab ntsuas kom kuaj xyuas yog tias cov neeg xaiv tau sib phim, txiav txim siab qhov twg lub diode muaj qhov zoo thiab qhov twg tiv tauj tsis zoo.
Kauj ruam 3
Sawb lub xov hlau nrog cov xaim txiav tawm, solder lub resistor mus rau qhov zoo hu ntawm lub txuas. Npog qhov txuas nrog cua kub ntsws. Muag qhov zoo tus lej ntawm LED mus rau lub koob thib ob ntawm lub resistor. Npog cheeb tsam soldering nrog tshav kub ntsws tubing. Siv lub koob tsis zoo ntawm LED thiab cam nws mus rau hauv av tus pin ntawm qhov txuas.
Kauj ruam 4
Txuas lub LED rau lub hwj chim thiab tshawb xyuas yog tias nws ua haujlwm.
Kauj ruam 5
Txuas mus rau USB cable Koj tuaj yeem txuas cov LED rau USB cable. Muaj ob hom ntawm cov cable no, tab sis lawv tsis muaj qhov sib txawv hauv chav ua haujlwm, yog li nrhiav cov cable tsis tsim nyog thiab tau pib. Muaj plaub tus neeg nyob hauv USB cable, ob ntawm cov ntaub ntawv xa mus, ib qho kev sib cuag yog " hauv av ", thiab lwm qhov hloov mus rau qhov hloov voltage … Nws yog rau nws tias koj yuav tsum txuas cov LED. Siv lub tshuab ntsuas ntsuas los ntsuas qhov ntsuas qhov ntsuas thiab txiav txim siab qhov zoo thiab qhov tsis zoo ntawm lub diode. Muag lub resistor mus rau qhov zoo hu, npog lub ham nrog tshav kub ntsws. Txuas tus pin zoo ntawm LED mus rau lub koob thib ob ntawm lub resistor thiab kaw qhov muag. Solder qhov tsis zoo ntawm cov diode rau hauv av sib cuag, npog xov tooj nrog cov kub kom sov. Txuas lub USB cable rau koj lub khoos phis tawm thiab xyuas seb nws puas ua haujlwm.
