描述

這就是讓我進(jìn)入 Arduino 的原因。我遇到了尼克的 LED 字時(shí)鐘，我想我想做那個。

自從下載了他的代碼后，我對其進(jìn)行了修改，加入了額外的傳感器和按鈕，并添加了一個 ESP01。

BH1750 用于根據(jù)光線條件自動調(diào)暗顯示屏，并且可以在夜間關(guān)閉顯示屏。BME280 顯示溫度、濕度和壓力。ESP01 用于從 pool.ntp.org 獲取時(shí)間。

額外的按鈕可以輕松調(diào)整設(shè)置。您可以使用按鈕調(diào)整光傳感器設(shè)置，以及更改字體和 NTP/DST/UTC 設(shè)置。

我對字時(shí)鐘做了相當(dāng)多的改變，它現(xiàn)在有更多的字，并且已經(jīng)移動了很多到 PROGMEM 以節(jié)省 RAM。

代碼現(xiàn)在已經(jīng)完成，除了一些未知的錯誤和這里和那里的調(diào)整之外，我會為它做一個案例。

您將需要調(diào)整光傳感器代碼以匹配您的光照條件，我在明亮的陽光下坐在窗戶旁邊進(jìn)行了編碼。

ESP01 用于通過 NTP 獲取時(shí)間，ESP01 在不需要時(shí)被編碼為睡眠（wifi 關(guān)閉），并通過串行喚醒以獲取 UNIX 格式的時(shí)間。為了方便起見，SSID 名稱和密碼通過 Arduino 代碼傳遞。

此版本還具有 DST/UTC 和 BST 計(jì)算。可以通過菜單調(diào)整或禁用這些設(shè)置。

設(shè)置保存到 EEPROM，這意味著如果您關(guān)閉電源并重新打開，您通過菜單所做的更改將被保存。

這些是 Github 上的代碼文件：

Code on Github [https://github.com/Ratti3/miniclock]:

    ProgmemData.h
Arduino
    ESP-01_NTP.ino
    LEDClock32x8_ESP01-NTP.ino
    ProgmemData.h

當(dāng) ESP01 運(yùn)行時(shí)，Arduino Serial 將顯示：

ESP01 版本，ESP01 需要一個 3.3v 穩(wěn)壓器，可以提供足夠的電流

僅 Arduino 版本

1 / 4

1 / 2

1 / 3

把它們放在一起：

1 / 10

1 / 8

接線：

DS3231, BH1750 and BME280:
 SCL PINS = A5
 SDA PINS = A4
 VCC = 3.3v
LED Matrix:
 CLK = D11
 CS  = D10
 DIN = D12
 VCC = 5v
Switches:
 D2 - Menu
 D3 - Date / +
 D4 - Temp / -
 D5 - Display options
ESP01 - Optional
 D7 - TX pin of ESP01
 D6 - RX pin of ESP01

這些是您可以更改的全局變量：
