I want to use two MPU6050 as movement sensors to analyse movements of a human.
Originally I wanted to use a normal ESP8266 + MPU6050 + Arduino Uno. It all worked out quite well, but I want to make the whole setup a bit smaller because I want to place one sensor on each wrist, and that would be an Arduino Uno on each wrist.
So I want to read Sensor Data from a MPU6050, transfer it to a NodeMCU and send it to my PC.
Before I order the NodeMCU and start working I want to ask some things:
Is there something special I should consider before I buy the NodeMCU?
I was considering this one:

I know that I can use Arduino IDE to programm the NodeMCU, but is it convenient? Is it easier with Lua? Is there a better way to do it than Lua and Arduino?
Right now my MPU6050 SCA and SCL are going into the Arduino Uno Pin A4 and A5. The NodeMCU only has one analog Input, how do I overcome this problem?
