Realtime control of NodeMCU (arduino) board through Node.js server


Create a near real time connection between a node.js express server and a NodeMCU Board (e.g. using [url removed, login to view]). This is for motor control use as a telepresence pet minding device/robot. (It will use a completely separate mobile system (Skype) for camera which is not part of this project.).

1. Requirements:

Authentication is required (can be a client with SSL of server number written in the code for the arduino sketch)

NodeMcu Esp8266 Dev board connects to an internet webserver using wifi

When a user presses a key e.g. 'W', 'A', 'S, ''D' the server must be able to send numbers to the size of 0 to 999 (or other method) to the NodeMCu board. (I will then program the board to use this data to control motors/sensors/etc on the device.)

Lag time from keypress in browser to motor output should be small enough to allow remote control driving

Code language: C/C++/Arduino or javascript uploadable through arduino sketch software onto the NodeMCU Board, Board must not need to be tethered or have to connect with a computer on a local network to run.

Code language: node.js with standard express framework for the web server

Code must be able to be legally used for a commercial product (must not be copywrited or patented code or otherwise unusable due to reserved intellectual property rights)

I, the Buyer on [url removed, login to view] gain the copyrights to any new software created during hired hours.

Board details: NodeMCU1.0 (ESP12E Module), [url removed, login to view]

2. constraints:

-communication should be as close to real time as possible

-Minimise using up of storage on chip so motor control, sensors etc code can be added

-Host compatability: the web server must be able to be hosted on Heroku (I can buy a SSL certificate)

Other boards:

There is the possibility of considering the use of another board/WIFI, if this board will not work or a better board/WIFI setup can be found. It must have/be:

-well stocked (there must be lots of them for sale (many suppliers or one supplier with over 2000 units)), ongoing production)

-priced under $16 AUD including WIFI excluding delivery

-programmed in C/C++/Arduino or javascript/node.js

-has 9+ GPIO pins pre-soldered

-no soldering required

-does not require serial connection to computer to run

-similar or less power consumption

-3.3, 4.8, 5, 6 or 12 volts

-WIFI FCC compliant

-good enough storage/speed
