Tsim qhov me me oscilloscope. Zaus ntau yog txog 40KHz (25uS puv npo) Hauv 4 qib xaiv tau. Cov tswv yim hluav taws xob nyob nruab nrab ntawm 50mVpp thiab 50Vpp hauv 2 qhov kev xaiv xaiv. Kev nce tau yog kho tau ntawm 1 txog 100. Txais AC lossis DC cov tswv yim. Nws pib-ua haujlwm cheb kom "khov" cov duab yoj. Kev cheb dawb tau los ntawm kev teeb tsa lub hwj chim ntawm ob qho teeb meem. Y-axis hloov kho rau nruab nrab nthwv dej. Khiav los ntawm roj teeb 9V.
Kauj ruam 1: Saib Video
Kauj ruam 2: Schematic
Txuas mus rau: High-res schematic
Kauj Ruam 3: Txheeb Sijhawm
Lub sijhawm cheb tau hloov kho hauv 4 qib qis txog 25uS (40KHz voj voog puv npo).
Kauj Ruam 4: Y-axis Kho
Siv nws los nruab nrab cov yoj zaub.
Kauj Ruam 5: Tswv Yim Tau Txais Kev Kho
Cov tswv yim ntau yog 50mVpp txog 50Vpp hauv 2 qhov xaiv tau. Cov tswv yim nce tau sib txawv los ntawm 1 txog 100.
Kauj Ruam 6: Pib Pib / Pub Dawb
Nws pib ua haujlwm cheb kom "khov" cov duab yoj. Kev cheb dawb tau los ntawm kev tso lub hwj chim ntawm ob qho chaw teeb tsa.
Kauj Ruam 7: Cov Thaiv Tseem Ceeb (5 Duab)
Kauj Ruam 8: Ua Ntej Ua Haujlwm Hauv Circuit (13 Duab)
Kauj Ruam 9: Daim duab (5 Duab)
Sau daim ntawv sweep lub sij hawm potentiometer los ntawm 0 txog 10, thiab siv cov kab ntawv no los nyeem lub sijhawm cheb (lossis zaus) hauv 4 thaj tsam. Ua tib yam rau qhov nce potentiometer.
Kauj Ruam 10: Daim Ntawv Teev Npe
Kauj Ruam 11: Pinouts (5 Duab)
Cov no yog cov pinouts rau IC's thiab LED matrix. Yog tias koj hloov LED matrix, txheeb xyuas qhov pinout. 7X5 coj matrix yuav tsum yog ib qho anode.
Kauj Ruam 12: Cov Lus Qhia Tshwj Xeeb
Thaum nyob rau hauv hom pib-ua haujlwm koj tau txais cov lus qhia no cheb lub sijhawm yog siab dhau lossis qis dhau nrog kev hwm ntawm cov tswv yim yoj, kho ntau yam/lub zog.
