## Intro
Workshop materials for the IoT hand-on training. The training is based on the [ESP8266](http://espressif.com/en/products/hardware/esp8266ex/overview) chip and [Arduino](https://github.com/esp8266/Arduino) framework.
The training was first done at the [TWF 2016 Conference](http://twf.community).
The idea behind the workshop is to have a step-by-step tutorial on building *Internet of Things (IoT)* solutions.
The initial exercises are simple and evolve over time.
If any questions please email me.

## Prerequisites
#### Software
Ensure you have installed:
* [PlatformIO](http://platformio.org/) IDE (for the IoT device)
* Download from: http://platformio.org/platformio-ide
* Also follow the [installation guide](http://docs.platformio.org/en/stable/ide/atom.html#installation)
* Ensure you install *clang* to have code completion.
* Ensure you install Python.
* [Visual Studio 2015 Community](https://www.visualstudio.com/en-us/products/visual-studio-community-vs.aspx) IDE (for the control app)
Windows PC is required.
#### Hardware Checklist

* Adapter board ESP8266 ESP-12 / 12E / 12F / 07
* USB-UART (flasher)
* Converter USB-UART PL2303 - microUSB slot
* MicroUSB cable B-A
* Sensors
* Motion detector PIR HC-SR501
* Transmitter IR 5mm 940nm (TSAL6400)
* Infrared Receiver 38 kHz (TSOP4838)
* Humidity detector DHT22 AM2302
* Module with 2 relays (photo-optic isolation)
* Power

## Essentials
### PlatformIO
Most important commands in PlatformIO:
* **Serial Monitor**
* PlatformIO > Serial Monitor
* Shortcut: **Alt+Shift+M**
* **Build**
* PlatformIO > Build
* Shortcut: **Alt+Ctrl+B**
* **Upload**
* PlatformIO > Upload
* Shortcut: **Alt+Ctrl+U**
### ESP8266
#### Boot Modes
Whenever the ESP is reset or powered on it checks the state of three GPIO pins to enter one of the boot modes:
GPIO15|GPIO0|GPIO2|Mode
------|-----|-----|----
LOW| LOW| HIGH|UART Bootloader
LOW| HIGH| HIGH|Boot sketch
HIGH| x| x|SDIO mode (not used for Arduino)
* LOW = connected to GND
* HIGH = connected to 3.3V
The *UART Bootloader* mode is used to upload our program.
The *Boot sketch* mode is used to execute our program (normal mode).
At startup ESP prints out the current boot mode:
```
rst cause:2, boot mode:(3,6)
```
More details are provided on the [ESP Arduino wiki](https://github.com/esp8266/Arduino/blob/master/doc/boards.md#boot-messages-and-modes).
#### Layout
The ESP8266 12E looks like this:
During the workshop we are sing a breadboard adapter:
