Waveshare elektron siyoh displeyi aniq voltmetr (0-90v DC) Arduino Nano bilan: 3 qadam

2024 Muallif: John Day | [email protected]. Oxirgi o'zgartirilgan: 2024-01-30 13:23

Ushbu yo'riqnomada men Arduino Nano, kuchlanish bo'luvchi va ADS1115 bilan jihozlangan 2,9 dyuymli elektron qog'oz displeyidan foydalanaman.

Bu ko'rsatma oldingi ikkita loyihani birlashtiradi:

1 -qadam: Keling, komponentlarni ulaymiz

Men komponentlarni quyidagicha uladim:

Waveshare displeyi:

Arduino -ni ko'rsatish

BUSY D7

RST D8

DC D9

CS D10

Din D11

CLK D13

GND GND

VCC 3.3V

ADS1115:

ADS1115 Arduino

VCC 5V

GND GND

ADDR GND

SCL A5

SDA A4

AIN0 kuchlanish bo'luvchi

Voltaj bo'linishi uchun men bu safar 680Kohm va 10Kohm rezistorlardan foydalandim. Men har doim aniqlik uchun qarshilik qiymatlarini o'lchayman.

Voltaj bo'linishi uchun hisob -kitoblar turli xil qarshilik qiymatlaridan foydalanmoqchi bo'lsangiz, hisob -kitoblarni avtomatlashtiradigan ushbu jadvalda mavjud: Google Sheet -ga havola. E'tibor bering, faylni tahrirlash mumkin emas, uni o'zgartirish uchun uni yuklab olish yoki diskdan nusxa ko'chirish kerak.

2 -qadam: kod

Displey va ADC kodi juda katta va agar men ekranda katta belgilar ishlatsam, arduino -da xotira etarli bo'lmaydi.

Buni hal qilish uchun men matnni o'z ichiga olgan tasvirni yaratish orqali matnni kodga aylantirdim, so'ngra ushbu onlayn asbob yordamida tasvirni arduino tomonidan o'qiladigan kodga aylantirdim:

Men hali ham ba'zi shriftlar va belgilarni ishlatardim, lekin xotirani saqlash uchun batareya quvvati va zaryadlanish foizini ko'rsatish uchun faqat raqamlardan iborat shriftdan foydalanaman.

Bu kod batareya zo'riqishini ko'rsatadi va zaryadlanish foizini ko'rsatadi, agar 90vda batareya zaryadlangan bo'lsa va 0vda batareya to'liq bo'sh bo'lsa. Bu sizning ehtiyojlaringizga mos ravishda o'zgartirilishi mumkin.

3 -qadam: Sinab ko'raylik:)

Men natijalardan juda xursandman.

Haqiqiy kuchlanishdan minimal og'ish (0,2 voltdan kam) bilan taxminan 9v dan 85v gacha bo'lgan bir qator kuchlanishni sinab ko'rdim.

Yaxshi korpusga o'ralganidan so'ng, bu juda yaxshi muhitda o'qilishi mumkin bo'lgan kichik voltli o'lchagichni yaratishi kerak:).
