ESP8266 Wifi Nodemcu
- 2. NODEMCU | Overview The NodeMcu is an open-source firmware and development kit that helps you to Prototype your IOT product within a few Lua script lines. Power: Input Voltage : 3.3V DC Current : 250mA Memory: RAM 32Kb DRAM 80Kb Flash 200Kb
- 3. NODEMCU | What is it? An Arduino-like device Main component: ESP8266 With programmable pins And built-in wifi Power via USB Low cost The NodeMCU (Node MicroController Unit) is an open source software and hardware development environment that is built around a very inexpensive System-on-a-Chip (SoC) called the ESP8266.
- 4. NODEMCU | What you can do with it? Program it via C or LUA Access it via wifi (ex. HTTP) Connect pins to any device (in or out)

It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor. ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors specific devices through its GPIOs with minimal development up-front and minimal loading during runtime.

Sample code led blink void setup() { pin Mode(13, OUTPUT); // initialize digital pin 13 as an output. } void loop() // the loop function runs over and over again forever. { digital Write(13, HIGH); // turn the LED on (HIGH is the voltage level) delay(1000); // wait for a second digitalWrite(13, LOW); // turn the LED off by making the voltage LOW delay(1000); // wait for a second }
