Waveshare E-ink дисплейі дәл вольтметр (0-90v DC) Arduino Nano көмегімен: 3 қадам

2024 Автор: John Day | [email protected]. Соңғы өзгертілген: 2024-01-30 10:22

Бұл нұсқаулықта мен электронды қағаз дисплейінде тұрақты токтың 90 вольтіне дейінгі дәл кернеулерді көрсету үшін Arduino Nano, кернеу бөлгіш және ADS1115 бар 2.9 дюймдік Waveshare электронды қағаз дисплейін қолданамын.

Бұл нұсқаулық алдыңғы екі жобаны біріктіреді:

-Arduino Volt Meter (0-100V DC)-2-нұсқа-https://www.instructables.com/Arduino-Volt-Meter-0…

-Электронды қағазды көрсету Arduino көмегімен ішінара жаңартылады-https://www.instructables.com/E-Paper-Display-Part…

1 -қадам: Компоненттерді қосамыз

Мен компоненттерді келесідей жалғадым:

Waveshare дисплейі:

Arduino дисплейі

BUSY D7

RST D8

DC D9

CS D10

DIN D11

CL13 D13

GND GND

VCC 3.3V

ADS1115:

ADS1115 Arduino

VCC 5V

GND GND

ADDR GND

SCL A5

SDA A4

AIN0 кернеу бөлгіш

Кернеуді бөлу үшін мен бұл жолы 680Км және 10Км резисторды қолдандым. Мен әрқашан дәлдік үшін қарсылық мәндерін өлшеймін.

Кернеуді бөлуге арналған есептеулер резистордың әр түрлі мәндерін қолданғыңыз келсе, есептеулерді автоматтандыратын осы кестеде бар: Google парағына сілтеме. Назар аударыңыз, бұл файлды өңдеу мүмкін емес, оны өзгерту үшін оны жүктеу немесе дискіге көшіру қажет.

2 -қадам: код

Дисплей мен ADC үшін код өте үлкен және егер мен экранда үлкен таңбаларды қолдансам, arduino -да жад жеткіліксіз болар еді.

Мұны шешу үшін мен мәтінді суретті жасау арқылы мәтінді кодқа айналдырдым, содан кейін суретті arduino оқитын кодқа түрлендіру үшін:

Мен әлі де кейбір қаріптер мен таңбаларды қолдандым, бірақ мен жадты үнемдеу үшін аккумулятордың кернеуін және зарядтау пайызын көрсету үшін сандары бар қаріпті ғана қолданамын.

Бұл код аккумулятордың кернеуін көрсетеді және зарядтау пайызын көрсетеді, егер 90в кезінде батарея зарядталған болса және 0в кезінде батарея толығымен бітеді. Бұл сіздің қажеттіліктеріңізге сәйкес өзгертілуі мүмкін.

3 -қадам: Оны тексерейік:)

Мен нәтижелерге өте қуаныштымын.

Мен нақты кернеуден минималды ауытқумен (0,2 вольттен аз) шамамен 9 в -тан 85 в -қа дейінгі бірқатар кернеулерді тексере алдым.

Жақсы корпусқа оралғаннан кейін бұл өте жарқын ортада оқуға болатын жақсы кішкене вольт өлшегіш болуы керек:).
