My slide at the Milan Codemotion 2015, a session called "An Adventure with ESP8266 and IOT" about using the esp8266 with NodeMCU, mosquitto, nodejs and an accelerometer. the pin labelled "IN" reads "This module is low-level trigger, the voltage value between 0-1. Greatly speed up your IOT application developing process. The RX pin is the input into the module and is 5V compliant (there is a level shifter on this pin). In this tutorial we’ll show you how to use analog reading with the ESP8266 using Arduino IDE, MicroPython or Lua firmware. 1B 1 I Channel 1 through 7 Darlington base input 2B 2 3B 3 4B 4 5B 5 6B 6 7B 7 1C 16 O Channel 1 through 7 Darlington collector output 2C 15 3C 14 4C 13 5C 12 6C 11 7C 10.
