There are various important factors for choosing the type of board for an IOT system, such as the number of GPIO pins, communicating protocols, including an antenna, and etc.Īlso, there are different boards and platforms, each has its specific features. What other boards can I use instead of NodeMCU?
#ESP8266 FIRMWARE ARDUINO IDE SERIAL#
Serial.println ( "HTTP server started" ) Īfter opening the Serial Monitor, if the Internet connection is established, you will be given the IP address of the page you have created (for example 192.168.1.18).copy and paste it in your browser to open the HTTP page. Serial.print("Configuring access point.") */Ĭonst char *ssid = "*****" //Enter your WIFI ssidĬonst char *password = "*****" //Enter your WIFI password * Set these to your desired credentials. Once you upload an Arduino sketch, the NodeMCU firmware gets erased. It can be either AT Commands Firmware, NodeMCU Firmware or Arduino based code. IMPORTANT NOTE: Only one firmware can exist on the ESP8266. In this example, you can control an LED by pressing the ON and OFF key.Įnter your modems SSID and password in the provided part and upload it on your NodeMCU board using Arduino IDE. So, many of us are actually using the board called NodeMCU and programming it with Arduino IDE and not the Lua Scripts. You can connect the internet through Wi-Fi using NodeMCU, and apply your desired commands by creating an HTTP page. Also, you can use pin D2(GPIO4) as SDA and pin D1(GPIO5) as SCLĬontrolling LED through an HTTP page Using NodeMCU So you should set up the pin number 13 whenever you want to use D7 in your program. For example, the D7 pin is defined as GPIO13. In order to use digital pins, you should select GPIO numbers. Containing 13 GPIO pins, 10 PWM channels, I2C, SPI, ADC, UART, and 1-Wire.practicable in Event-driven API applications.Available as an access point or station.Programmability with Arduino IDE or IUA languages.The general features of this board are as follows: In addition, by providing some of the most important features of microcontrollers such as GPIO, PWM, ADC, and etc, it can solve many of the project’s needs alone. NodeMCU is an open source platform based on ESP8266 which can connect objects and let data transfer using the Wi-Fi protocol. There are several ways to connect objects such as Wi-Fi protocol. Today, IOT applications are on the rise, and connecting objects are getting more and more important. Introducing boards that can be used instead of NodeMCU.
