Video: Me me LED ntsais daim duab: 6 Cov kauj ruam
2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:24
Koj tuaj yeem ntsais muag LED yooj yim nrog arduino lossis 555 lub sijhawm. Tab sis Koj tuaj yeem ua qhov txuas ntsais muag yam tsis muaj ICs. Nov yog qhov yooj yim ntsais muag daim duab ua los ntawm qhov tsis sib xws.
Khoom siv
NPE transistor
2sc1815 x 2 lossis ib qho me me NPN transistor
Capasitor
47f2x wb
Resistor
4.7KΩ x 2, 1KΩ x 1, 100 Ω x 1, 0 Ω x 1
Roj teeb
CR2032x 1
LED
Liab, Ntsuab lossis Daj x 1
- Tooj phaj
- Cov hlau xaim
Kauj ruam 1:
Nov yog daim duab qhia chaw. Nws hu ua "astable multivibrator". Yog tias koj txaus siab, google nrog lo lus no.
Kauj ruam 2:
Muab cov seem tso rau hauv ntawv yuav txo qhov ua yuam kev.
Kauj ruam 3:
Transistors, LED, thiab cov khoom siv hluav taws xob muaj qhov taw qhia ruaj khov. Tshwj xeeb tshaj yog rau transistors, tus pin teeb sib txawv nyob ntawm seb hom, yog li nws tau pom zoo kom txheeb xyuas cov ntawv teev npe.
Kauj ruam 4:
Xa mus rau daim duab seb yuav npaj cov khoom li cas. Kuv pom zoo kom siv breadboard ua jig. Ntxig E tus pin ntawm tus transistor rau hauv lub khob cij, thiab muab tus pin B txuas rau sab tsis zoo ntawm lub capacitor, tus pin C rau sab zoo, LED, thiab tus tiv thaiv hauv qhov kev txiav txim no. 0Ω resistor tau siv ua tus pas uas daim duab tuav hauv nws txhais tes. Tej zaum nws tsuas yog xaim tooj liab.
Kauj ruam 5:
Nco ntsoov tias koj tsis tau hnov qab tus laug thiab nws tsis tau luv. Cia peb tig lub zog. Muab CR2032 sab tsis zoo rau phaj tooj liab, sawv ntawm daim phaj tooj liab thiab lo tias daim duab tuav rau saum lub roj teeb.
Kauj Ruam 6:
Daim duab uas kuv tau ua yog ntsais muag txog 4Hz nrawm. Yog koj xav hloov ceev. Sim hloov hom ib feem. Piv txwv
- 4.7KΩ Resistor rau 10kΩ lossis 47kΩ, ntsais ntsais nrawm yuav qeeb
- 47μF Capasitor rau 100μF, ntsais nrawm yuav qeeb
