我正在为圣诞节的朋友创建 METAR 地图，并正在考虑为他创建一种更简单的方法来更改其 WiFi 密码，而无需操纵代码。做了一些研究，我发现了这个链接https://www. Circuitschools.com/change-wifi-credentials-of-esp8266-without-uploading-code-again/，但无法将其放在哪里以及我需要什么改变原来的代码。 https://github.com/WKHarmon/led-section/blob/master/led-section.ino是我用来启动的代码的链接。我能够让它工作得很好，但我只是想让它更容易设置。
