Red pin is connected to pin D5 of the NodeMCU board Blue pin is connected to pin D6 of the NodeMCU board Green pin is connected to pin D7 of the NodeMCU board Yellow pin is connected to pin D8 of the NodeMCU board Photoresistor is connected to Analog pin A0 via a 10K-Ohm resistor. Connect: VCC to 3. It became popular because it is a WiFi-ready microcontroller by itself – no need for an Arduino. The Adafruit Feather HUZZAH ESP8266 is an Arduino-compatible Wi-Fi development board powered by Ai-Thinker's ESP-12S, clocked at 80 MHz at 3. ESP8266 is a highly integrated chip designed for the needs of a new connected world. To solve this, we must type the Digital pin of Arduino which corresponds with the NodeMCU. USB cable to connect NODEMCU with laptop which have Arduino IDE. NodeMCU + PIR sensor HC-SR501 + ThingSpeak = Motion Detection alert Via Twitter. It allows you to control inputs and outputs as you would do with an Arduino, but it has Wi-Fi. Let’s write an Arduino sketch to set rising edge interrupt on 2nd GPIO pin of NodeMCU. 3 Inch OLED Board White $18.
