Qhov haujlwm no yog tsim kom muaj kev sib hloov ntawm lub sijhawm ua haujlwm. Hauv qhov haujlwm no tus neeg siv tuaj yeem teeb tsa ON timer thiab Off time siv cov yuam sij thiab 7 ntu tso saib. Kev xa tawm tau muab los ua qhov tso tawm, qhov chaw txuas yuav txuas rau ON rau ON lub sijhawm thiab nws yuav ploj mus tom qab ON lub sijhawm dhau mus. Thiab Relay yuav nyob twj ywm kom txog thaum Lub Sijhawm Ncua Sijhawm.
Peb Xav Tau 4 tus yuam sij rau kev ua haujlwm xws li Hloov tus lej, hloov tus lej thiab pib thiab nres lub sijhawm.
Kauj Ruam 1: Yuav Tsum Tau Muaj
Cov khoom siv xav tau yog raws li hauv qab no rau txoj haujlwm raws li hauv qab no
1 x PIC16F876A1 x PIC Dev Board
4x Keys
4 x 7 Segment Common Cathod lossis Common Anode
+5v Fais Fab Khoom
4 x BC547 Transistor
Kuv tau siv Common cathode 7 ntu nrog rau NPN transistor.
Kauj ruam 2: Kev ua haujlwm
Teem lub teeb timer siv cov yuam sij thiab tso tawm. Siv cov ntawv qhia zaub mov nkag mus rau hauv cov kev xaiv thiab teeb tsa ON lub sijhawm thiab Sijhawm Tawm.
Tom qab ntawd Pib lub timer, Timer yuav khiav txuas ntxiv mus.
Nov yog cov vis dis aus me me ntawm kev ua haujlwm ntawm qhov haujlwm:
