• Install the USB driver on your laptop (see "Install driver")
• Download the IDE (see "Integrated development environment")

Need wifi to download the driver and IDE? We've got you covered. At least in the hangar, that is. You can use the SoftwareCircus2017 hotspot, with password cloudbusting.

If want to learn more about the Internet of Things you could decide to buy my book. Greatly appreciated.

The files in this repository are part of the workshop Build your own Internet of Things appliance, on Software Circus 2017 Cloudbusting. Attendees of the workshop create their own real-life IoT appliance using a microcontroller called NodeMCU and some clever software that connects to the internet.

In order to program the NodeMCU, a computer with USB is required (modern laptops with USB-C require a USB 2.0/3.0 hub, for instance the MacBook Pro). Drivers and an IDE need to be installed before programming can take off. Attendees are encouraged to do install the appropriate driver and download the IDE (and if nessecary, Java) beforehand, to prevent wifi bandwidth degradation during the workshop.

In order to communicate with a NodeMCU via USB, a driver is needed. Drivers here are for Windows (CP210x_Windows_Drivers.zip) and OS X (SiLabsUSBDriverDisk.dmg). Install on your favorite platform and you're good to go.

A complete IDE is available, in the form of ESPlorer.jar, a Java program. Java needs to be already installed on your computer though. If nothing happens when you doubleclick ESPlorer.jar, you need to install Java as well.

In order to give you a running start, I've written a small introductory leaflet for Lua, called LUA-INTRO.md.

• blink.lua
  Flashes the D0 led on the NodeMCU with a 1 Hz frequency.
• wifi.lua
  Sets the wifi credentials and tests the connectivity by calling a webhook.
• testpir.lua
  Prints a message onscreen if a PIR sensor fires.
• pirtoifttt.lua
  Calls a webhook on IFTTT.com once a connected PIR sensor fires. Name of the IFTTT applet and the corresponding API KEY need to be filled in.
• testanalog.lua
  Print the current value of the analog port on screen.
• resistancetothingspeak.lua
  Calls a webhook on ThingSpeak.com with the current value of the analog port. The API KEY of the ThingSpeak channels needs to be filled in.
