ESP8266选型参考:(NodeMCU,WeMos及其它) ESP8266=arduino+wifi+flash,然而,它的价格比arduino还便宜。所以是不是arduino已经完败了呢?不不不,analog pin还是没有人家多的,再然后还是有些开源固件是针对arduino平台的,比如3d打印机的marlin,传统飞控等,这些都不好直接替代,不过关于IOT的大多数应用,ESP8266必须赢。 ES...

**Robust and Reliable Performance** The Nodemcu ESP8266 development board is built to last, with a robust design that can withstand a wide range of temperatures from -30°C to 70°C. The board's 16 digital I/O pins and 1 analog input pin allow for a variety of sensors and actuators ...
Best Pins to Use – ESP8266 One important thing to notice about ESP8266 is that the GPIO number doesn’t match the label on the board silkscreen. For example, D0 corresponds to GPIO16 and D1 corresponds to GPIO5. The following table shows the correspondence between the labels on the silk...

This is advance tutorial it uses knowledge for JavaScripts, ESP8266, CSS and HTML. In this example we are reading analog value of ADC and display it..
The ESPs with more pins often also have an analog pin with which we can measure voltages up to 3.3V. The problem, however, is that the Li-Ion battery can output up to 3.7V (some sources even speak of up to 4.2V). This voltage can damage the ESP, so we need to get the voltage...
are these pin S2 and S3 that represent GPIO9 and GPIO10. I want to use these pin but it does not behave like the other GPIO pin. I need help to understand what is pin S2 and S3. Please explain to me why it behave differently with the other GPIO. How can I use these two pins?
