esp01s Internet of Things desktop ornaments

I just have a 1.3-inch OLED and esp01s that have been idle for half a year. I made an Internet of Things desktop ornament that can display the weather temperature conditions for three days and the number of fans of station B. It supports ssd1306 and sh1106 OLED screens, and supports fixed WiFi account password or web Web WiFi connection; powered by 3.7v lithium battery, added tp4506 charging and indication circuit and 431 low battery indication circuit, the interface uses micro usb, don't say why not use tpc, mainly because I only have this on hand, clear materials, want to use tpc Just change the interface yourself. I don’t know how to put the demonstration video in the description, but put the code and video in the attachment below. If you need it, please mention it yourself. You can also use the code of Invention Control, but I use io0 to drive the oled. If it is set to 0, it will affect the oled screen display, let alone scanning the QR code to connect to WiFi. It is best to use tx and rx to drive the oled to run. Invention control routine of scanning code to connect to WiFi
