On the board of NODEMCU, there is the other LEDs what can be tested. 1. First LED Through the PCB file of NODEMCU (see Figure-1 or Https://github.com/nodemcu/nodemcu-devkit-v1.0/blob/master/NODEMCU_DEV Kit_v1.0.pdf), we can find the first led which connected by GPIO16 and vdd3v3. The index of PIN is 0. (see another ar

This is the use of this paragraphBecause this default is the firmware that supports the AT command, so we're going to brush Nodemcu'sFirst look at the wiringGPIO0 default is operating mode (no wiring). If the next low level is the download mode (to the module brush firmware!!) ) So the low level is connected. CH_PD high level, the rest can not be wired except TX,RX.The rest is actually almost the same as my article NODEMCU preliminary studyThe first i

The NODEMCU is a compact development board with integrated WiFi and MCU, based on the ESP8266 chip. Forum in http://bbs.nodemcu.com/, source code in HTTPS://GITHUB.COM/NODEMCU.Using the Openscad to make a shell, you can use the 3D printer output, and no longer "bare-Ben".OPENSCAD's original model file is as follows, which can be modified and output on the 3D printer itself.NODEMCU Smart Device, box, Rainproof (vertical mount)//author:[emailprotected],

NODEMCU's documentation finally found that ESP8266 's GPIO 2 is indeed a PIN 4,gpio 0 is pin 3. Https://github.com/nodemcu/nodemcu-firmware/wiki/nodemcu_api_cn In other words, this API is not for the Earth people to see. According to the instructions, Net.createserver returns the Server, in fact, if using UDP, according to the code inside you do not work out. Finally found the answer in the Www.esp8266.com

steps as follows: Esp8266 terminal callWiFi.beginSmartConfig()The user name and password that will be sent by the mobile phone. Enter the current network password and send it to the UDP port.

JavaScript Development gesture Control Basics"HardwareEarlier I saw that Arduino encapsulated the API in a DSL when it was compiled. The NODEMCU is built with the support of the Lua language, allowing the beginning to start with Lua. And Tessel was born to provide JavaScript runtime environment, we write need to write good JavaScript can be run on it.Tessel 2 is a relatively high-configuration hardware, but low-matching it?Samsung designed the Jerrys

Due to the widespread use of the COM protocol, many devices, although the interface changed to USB, but the internal data communication protocol is still using COM (that is, the traditional RS232 serial port protocol, the new use of TTL). Many devices use PL2302/CH340/FTDI and other chips to simulate the serial port protocol via USB, such as ARDUINO/NODEMCU, etc., using a similar mechanism.Under Windows, after you install the driver, you can find the
