ESP8266 w/ Espruino runtime sending GET requests to Express server.

Button Press sends GET request to Express Server

This project will connect your controller to wifi, and connect to an Express server running on your computer,

Prerequisites

1. You will need a supported ESP8266 microcontroller. Preconfigured boards, thus far, are:

• Adafruit's Feather Huzzah
• NodeMCU

1. Your hardware should be flashed with ThingsSDK Flasher.js using the latest Espruino JS runtime.
2. You should have ThingsSDK-cli installed.

board setup

On a breadboard, connect 3v and ground to the rails, then wire ground to button to pin (except pin 15 on Feather Huzzah, which has a built-in pulldown resistor and needs to be wired to 3v rail).

deploy

clone this repo, edit the skeleton.config.js to add your local environment information, then run the following:

npm i
npm run projectInit
thingssdk devices
npm run push

In another terminal, run node api to start the Express Server.

Now, press a button!

known issues

• if you add debounce to the options object passed to setWatch, the e object passed to the handler function no longer contains the pin property.

known bugs

• debouncing issues with pins other than 15 on Feather Huzzah. One press can get you multiple API calls.
