Hi I have a version of the esp8266 with 1 analog pin, TX and RX pins. I'm looking to attach a temperature sensor (Grove - I2C High Accuracy Temperature Sensor - MCP9808), humidity, and a few others in addition to controlling a logic-level MOSFET for LED control.
What would I use for this? Would a multiplexer like the CD74HC4067 or the MCP23017 - i2c 16 Input/Output Port Expander work?
Basically, I need to both expand serial/digital input and still have at least 1 output control.
