Thawj qhov kuv tau ua yog txuas kuv Grove Heart rate sensor rau kuv Arduino ntawm qhov yooj yim heev los ua raws kev qhia hauv YouTube.

Qhov txuas YouTube tau muab hauv qhov swb yav dhau los kuj hais txog tsab ntawv koj tuaj yeem luam tawm hauv koj tsab ntawv Arduino.

Tam sim no koj tuaj yeem hloov kho tus lej xws li ntau npaum li cas ib pliag nws rov los tus nqi ntawm koj lub plawv tam sim no.

Kauj Ruam 2: Txuas Koj Cov LED Sawb

Tom qab koj muaj koj lub plawv ntsuas lub ntsuas thiab ua haujlwm nws yog lub sijhawm ntxiv koj lub teeb LED rau hauv koj qhov project.

Txhawm rau kom tau txais cov ntawv xeem rau koj LED (ws2812) koj xav mus rau sab saum toj thiab mus rau Cov Cuab Yeej> Tswj Cov Tsev Qiv Ntawv, thiab tshawb "Adafruit NeoPixel" thiab rub nws. Los ntawm qhov ntawd koj tuaj yeem mus rau Cov Ntaub Ntawv> Xeem> Adafruit NeoPixel thiab xaiv cov ntawv xeem uas koj nyiam.

Tam sim no txhawm rau txuas koj cov xov tooj liab thiab dub rau GRN thiab 5V hauv koj lub rooj tsav xwm dub. Tom qab ntawd koj txuas koj lub tsho daj hauv qhov uas koj tsab ntawv xav kom koj muab tso rau hauv uas yog 6 hauv cov ntawv xeem los ntawm lub neej ntawd.

Tam sim no koj muaj ob qho ntawm koj cov khoom ua haujlwm tib lub sijhawm, nws yog lub sijhawm kom lawv ua haujlwm ua ke.

Ua ntej koj yuav tsum coj tus lej uas Lub Plawv ntsuas lub ntsuas pa tso tawm (c) thiab ua kom cov kab hluav taws xob LED tuaj yeem nyeem nws ntawm ib qho yog lwm nqe lus suav nrog hauv cov duab.

Tam sim no thaum lub plawv dhia ntsuas ntsuas muab qhov sib txawv <60 lub teeb yog xiav. Thaum nws yog 85 nws hloov liab.

Kuv sim nws tawm ntawm kuv cov phooj ywg hauv chav kawm kuv tus kheej thiab pom tias ntau ntawm lawv muaj lub plawv tsis tu ncua tsuas yog siab dua 80 yog li kuv txiav txim siab tso qhov pib ntawm 85. Qhov no yuav txawv ntawm ib tus neeg rau ib tus neeg thiab tseem nyob ntawm seb hnub nyoog koj cov neeg tuaj saib mus los siv nws, Kuv pom zoo kom koj sim nws rau tib neeg koj tus kheej yog li koj tseem tuaj yeem ntes lawv cov lus teb rau cov khoom no.

Thaum koj ua tiav nrog kev hloov kho koj yuav xav tau txuas qee cov xov hlau vim tias koj tsis xav kom koj cov xov hlau tsis xoob thaum tib neeg siv nws. Qhov kev sib txuas no tau ua tiav tau yooj yim heev thiab tseem siv qhov chaw me me uas los tau yooj yim rau cov vaj tsev.

Koj yuav xav siv cov xov hlau uas koj tau siv tag nrho lub sijhawm vim tias lawv muaj zog ntau dua li lwm tus. Muab cov xov hlau uas koj muaj tso rau hauv koj lub khob cij thiab muab tso rau hauv tooj liab, muaj tag nrho cov kab liab thiab dub nyob hauv kab sib cais. Tam sim no txiav qhov tsis kam thiab cov xov hluav taws xob los ntawm spool thiab muab lawv tso rau hauv lawv cov kab kev hwm (liab hauv kab liab thiab txho hauv kab dub). Tam sim no txuas ob kab hauv kab sib cais, txuas tag nrho cov xov hlau hauv txhua kab thiab tam sim no lawv txhua tus txuas nrog ib leeg. Tam sim no tso qhov xoob xoob xaim liab hauv 5v qhov thiab xaim xaim hauv GND qhov.

Thiab thaum kawg koj tuaj yeem lo koj cov hlua LED sab nraub qaum ntawm lub plawv kom tau txais qhov txias txias no los ntawm sab nraum qab ntawm lub plawv.
