Agogon dijital AT89C2051 Kayan aikin lantarki na DIY mataki-mataki haɗawa

Wannan jagorar aikin ta yi bayani dalla-dalla kan yadda ake haɗa kayan aikin agogon dijital bisa ga microcontroller AT89C2051 (wanda aka fi sani da C51). Wannan microcontroller mai ƙanƙanta kuma mai amfani da yawa ya dace da ayyukan DIY iri-iri. Gina wannan agogon yana ba da ƙwarewar koyo ta hannu a haɗin kayan lantarki da kuma shirye-shiryen microcontroller na asali. Agogon da aka gama yana ba da amfani a aikace kamar:

• Na'urar kiyaye lokaci mai sauƙi kuma abin dogaro ga wuraren aiki ko ɗakunan kwana.
• Kayan koyarwa ga lantarki da shirye-shiryen microcontroller.
• Tushe don ayyuka masu rikitarwa da suka shafi sarrafa lokaci.

Kayan Masu Amfani/Abubuwan Haɗi

Kayan aikin ya ƙunshi waɗannan abubuwa masu zuwa (a cikin bidiyo a 01:21):

• AT89C2051 Microcontroller
• Resistors guda biyu na 10kΩ
• Capacitors guda biyu na 30pF
• Capacitor guda ɗaya na 100nF
• Capacitor electrolytic guda ɗaya na 10µF
• Tsarin resistors guda ɗaya na 1kΩ (resistors 8 + fil ɗaya na gama-gari)
• Crystal oscillator na 12MHz
• Transistor 8550
• Maɓallan turawa guda biyu
• Soket IC mai fil 20
• Buzzer/magana na 5V
• Na'urar nuni mai kashi bakwai
• Toshe fil biyu
• PCB mai girman 52x42mm

Ana iya saukar da zanen tsarin dalla-dalla a robojax.com (a cikin bidiyo a 00:43).

Jagorar Haɗin Waya

An kwatanta tsarin haɗin waya sosai a cikin bidiyon. Zanen tsarin (a cikin bidiyo a 04:38) yana nuna haɗin kai tsakanin abubuwan. Ba a yi amfani da mai raba wutar lantarki a fili a wannan aikin ba; ana amfani da resistors da farko don iyakance wutar lantarki zuwa na'urar nuni mai kashi bakwai. Ana amfani da dabarar multiplexing don rage yawan wayoyin da ake buƙata don kunna na'urar nuni mai kashi bakwai (a cikin bidiyo a 05:56). Crystal na 12MHz yana ba da siginar agogo, wanda sai microcontroller ya raba shi zuwa 1Hz (a cikin bidiyo a 06:53).

Aikin Kai Tsaye/Nunawa

Bidiyon yana nuna tsarin haɗawa (a cikin bidiyo a 07:28) da kuma yadda agogon da aka gama yake aiki (a cikin bidiyo a 21:08). Ana kunna agogon da wutar lantarki ta 5V (a cikin bidiyo a 21:08). Ana amfani da maɓallai biyu don saita lokaci da kunna ayyukan ƙararrawa (a cikin bidiyo a 22:47). Bidiyon kuma yana nuna yadda ake saita ƙararrawa biyu (a cikin bidiyo a 23:14).
