If you have more information on required libraries, please make a comment. IRremoteESP8266 version 2.6.3, for infrared.PubSubClient version 2.7.0, by Nick O'Leary, for MQTT messaging. ![]() Note regarding libraries, I have installed to following for ESP8266 projects: Once you have confirmed that your IDE can be used to program your NodeMCU, move to the next step. + Initialized the on board LED digital pin for output. Also, messages are posted which can be viewed in the Arduino IDE Tools/Serial Monitor. While running the program, the onboard LED light will turn on for 1 second, turn off for 1 second, and continuously cycle. The LED lights will alternate on and off.ĭownload and run the basic Arduino test program: nodeMcuTest.ino. When the sample program is run, the on board LED will turn on, the external LED off, then the on board LED will turn off, the external LED on. The positive side of the LED is connected through a resister (500 to 5K ohm) to the NodeMCU pin D4. I plug the negative side of an LED into the ground (G or GND) pin on the NodeMCU. In my sample, I plug the NodeMCU into the Breadboard. ![]() Without the breadboard the onboard light will blink on and off which is effective for the test. You can test with or without a breadboard. ![]()
