Qhov laj thawj tseem ceeb rau qhov kev qhia no yog rau kev hloov kho lub teeb pom kev hauv qhov tsaus ntuj thiab teeb pom kev zoo. Qhov teeb meem tshwm sim rau kuv cov phooj ywg Srk thiab gaajar uas hnav tsom iav rau pom, tias lub teeb tsis txaus rau kev nyeem ntawv. Hauv cov lus qhia no peb yuav npaj iav thav duab uas yuav tsum tau hloov/tawm LEDs nyob ntawm qhov pom kev siv.
Khoom siv
Cov Khoom Siv thiab Khoom Siv: 1. Iav thav duab 2. Soldering pas nrig, Flux thiab Lead3. Cov hluavtaws hluavtaws 4. Micro LEDs 5. Cov tooj liab tooj liab thaiv los ntawm kev hloov pauv me me winding6. Tooj liab tooj liab 7. Transistor 2N2222 (NPN) 8. LDR (Lub teeb nyob ntawm tus tiv thaiv) 9. resistor (100k ohm) 10. Ferric chloride 11. Roj teeb (3.7V) Li - Ion
Kauj Ruam 1: Sau Micro LEDs:
1. Ua ntej tshaj plaws siv lub xov tooj ntawm tes qub thiab nrhiav cov LEDs sawb uas yog nyob rau sab qis ntawm cov zaub. 2. tshem tawm cov LEDs cais thiab muab cov kab txuas txuas rau cov LEDs. 3. Thiab siv cov pos hniav hluavtaws ntawm ob lub davhlau ya nyob twg ntawm LED.
Kauj Ruam 2: Tsim Circuit Court:
1. Sketch lub Circuit Court siv tus cim ruaj khov raws li daim duab qhia chaw. 2. Tam sim no siv cov pos hniav hluavtaws rau ntawm txoj kev kos duab ntawm tooj liab. 3. Thiab cia nws qhuav rau ib teev (1 teev).4. Thiab muab cov tooj liab tso rau hauv cov tshuaj ferric chloride. 5. Tom qab ntawd khaws nws qee lub sijhawm kom txog thaum cov tooj liab tsis xav tau yaj rau hauv cov tshuaj ferric chloride. 6. rov ua dua cov kauj ruam no rau ob sab Circuit Court rau lwm sab.
Kauj Ruam 3: Sib dhos:
1. Tom qab ntawd ntxiv cov kab hluav taws xob rau ob sab ntawm cov iav thav duab. 2. Txuas lub roj teeb mus rau cov kab hluav taws xob ua ke. 3. Tom qab ntawd xyuas lub tsom iav thaum muaj qhov pom kev thiab qhov tsaus ntuj
