Tiv thaiv ntoo

Thaum koj txaus siab rau lub moos nws yog lub sijhawm los xuab zeb nws thiab tiv thaiv nws nrog cov kua roj vanish. Kuv siv cov ntawv mos muag heev (tus nqi 500) los ua kom cov npoo muag muag. Kuv qhia koj kom siv cov kua roj vanish pob tshab, yog li cov xim ntoo tsis hloov pauv. Muab cov kua roj voos me me tso rau ntawm tus txhuam thiab rub nws mus rau qhov kev coj ua txhua xyoo hauv ntoo. Ua nws tsawg kawg 2 zaug.

Kauj ruam 10: Assamble

Firs muab cov nyees khawm thiab lub zog ntsuas ntawm lawv txoj haujlwm - yog tias koj lub qhov loj dhau, koj tuaj yeem siv qee cov kua nplaum kub los kho lawv hauv qhov chaw. Tom qab ntawd muab lub nplhaib khi rau hauv nws lub qhov thiab txuas nws cov xov hlau mus rau Arduino. Ua ntej koj lo lub nplhaib LED rau hauv nws qhov chaw nws yog qhov zoo kom paub tseeb, tias LED pixels nyob hauv qhov chaw raug - nyob nruab nrab thiab ua ke nrog daim duab. Txog lub hom phiaj ntawd kuv tau ntxiv thiaj li hu ua Kev Kho Mob uas yuav tso tawm txhua qhov tseem ceeb (0, 5, 10, 15,… ntawm feeb ntiv nplhaib thiab 3, 6, 9 thiab 12 ntawm lub nplhaib teev). Koj tuaj yeem nkag mus rau hom no los ntawm kev nias thiab tuav ob lub khawm, ua ntej ntsaws lub hwj chim rau lub txuas. Koj tuaj yeem tawm ntawm hom no los ntawm nias ib lub pob.

Thaum koj muaj koj lub nplhaib LED sib dhos, siv qee cov kua nplaum kub thiab tuav lawv thaum cov kua nplaum khov kho. Tom qab ntawd nqa koj lub PVC ib ncig thiab rov ua dua: siv qee cov kua nplaum kub rau LEDs, tso lawv sai thiab tuav lawv li ob peb feeb. Thaum kawg, thaum koj paub tseeb tias txhua yam ua haujlwm koj tuaj yeem kub kua nplaum rau ntawm ib lub rooj tsavxwm (lossis Arduino) rau ntoo. Tswv yim: tsis txhob siv cov kua nplaum ntau. Tsuas yog tus nqi me me thiaj li tuav hauv ib qho tab sis koj tuaj yeem tshem nws tau yooj yim yog tias koj xav hloov qee yam tom qab.

Thaum kawg, ntxig cov roj teeb ntawm tes rau nws tus tuav.

Kauj Ruam 11: Txhim Kho - Photoresistor

Lub moos cuam tshuam tshwj xeeb tshaj yog nyob hauv qhov tsaus ntuj. Tab sis qhov no tuaj yeem cuam tshuam nws cov neeg siv thaum hmo ntuj, thaum nws lossis nws pw. Tias yog vim li cas kuv thiaj txiav txim siab hloov kho lub moos nrog cov yam ntxwv ntawm kev kho qhov ci tsis siv neeg - thaum chav tsaus ntuj; lub moos hloov nws cov LEDs.

Rau lub hom phiaj ntawd, Kuv tau siv lub teeb pom kev zoo - cov duab tiv thaiv. Nws qhov kev tiv thaiv yuav nce siab ntxiv; txog li ob peb mega ohms thaum tsaus ntuj thiab nws yuav muaj tsuas yog ob peb puas ohms thaum muaj lub teeb ci rau nws. Ua ke nrog tus tiv thaiv ib txwm lawv tsim qhov faib hluav taws xob. Yog li thaum qhov tsis kam ntawm lub teeb pom kev hloov pauv, yog li qhov hluav taws xob ntawm Arduino analog pin (uas peb tuaj yeem ntsuas tau).

Ua ntej yuav siv cov tooj liab thiab sib sau ua ke ib qho Circuit Court, nws yog qhov zoo los sim nws ua ntej, yog li koj tuaj yeem pom tus cwj pwm thiab kho qhov raug.
