9. Tambayoyin da Ake Yi Akai-akai (FAQ)

Q: Shin zan iya tuƙa wannan nunin tare da microcontroller 5V kai tsaye?

A: A'a. Dole ne ku yi amfani da resistors masu iyakancewa ƙarfin wutar lantarki ko, zai fi dacewa, direbobin ƙarfin wutar lantarki na ci gaba. Ƙarfin wutar lantarki na gaba yana ~2.05V, don haka ana buƙatar resistor don sauke sauran ƙarfin wutar lantarki (misali, 5V - 2.05V = 2.95V) da saita ƙarfin wutar lantarki. A 20mA, R = 2.95V / 0.02A = 147.5Ω (yi amfani da 150Ω).

Q: Menene manufar anodes daban-daban don lambobi da maki goma?

A: Yana ba da damar sarrafa kai. Kuna iya haskaka Lamba 1, Lamba 2, da Lamba 3 a jere (haɗawa) ta amfani da anodes ɗin su, yayin da cathodes sashe suke gama-gari. Anode maki goma shima ya banbanta, yana ba ku damar kunna/kashe maki goma don kowane lamba da kansa a lokacin lokacin haɗawa.

Q: Ta yaya zan sami daidaitaccen haske lokacin haɗawa?

A: Tunda kowane lamba yana kan ɗan lokaci kaɗan (misali, 1/3 aikin aiki na lambobi 3), dole ne matsakaicin ƙarfin wutar lantarki a lokacin \"kan\" lokacinsa ya zama mafi girma don cimma matsakaicin haske iri ɗaya kamar lambar da aka tuƙa a tsaye. Idan matsakaicin ƙarfin wutar lantarki da ake nufi shine 5mA, matsakaicin ƙarfin wutar lantarki yayin bugun jini na haɗawa yakamata ya zama kusan 5mA * (Lambar Lambobi) = 15mA (don aikin aiki na 1/3).

Q: Takardar bayanin ta ambaci \"Kunshin Ba Mai Gubar.\" Menene tasirin solder?

A: Solder mara gubar yawanci yana da mafi girman ma'anar narkewa fiye da solder na gargajiya na tin-lead. Ƙayyadaddun yanayin solder na 260°C na dakika 3 yayi daidai da sifofin sake dawowa na gama-gari marasa gubar. Tabbatar da tsarin haɗawar ku ya cika wannan buƙatar don guje wa lalacewar zafi.
