PRODINo WIFI-ESP WROOM-02 Examples

It's an example shows how to use a PRODINo WiFi-ESP WROOM-2 device with http://www.blynk.cc/ (Blynk is designed for the Internet of Things. It can control hardware remotely, it can display sensor data, it can store data, visualise it and do many other cool things.).

Prerequisites: Before start this an example you need to install

1
Install Blynk library: SketchInclude libraryMenage Libraries... find Blynk and click Install
2
DHT library: https://github.com/adafruit/DHT-sensor-library
3
Connect DHT22 sensor to GROVE connector. Use pins:
- first sensor EXT_GROVE_D0, Vcc+, Gnd(-)
- second sensor (if you need) EXT_GROVE_D1, Vcc+, Gnd(-)

Pin maps PRODINo WiFi-ESP -> Blynk:

OptoIn and DHT data -> V0 {Type: "LCD", Mode: "Advanced", Input: "V0", Color: "Green" }
Relay1 -> V1 {Type: "Button", Name: "Relay 1", Color: "Green", Output: "V1", Mode: "Switch" }
Relay2 -> V2 {Type: "Button", Name: "Relay 2", Color: "Blue", Output: "V2", Mode: "Switch" }
Relay3 -> V3 {Type: "Button", Name: "Relay 3", Color: "LightBlue", Output: "V3", Mode: "Switch" }
Relay4 -> V4 {Type: "Button", Name: "Relay 4", Color: "Orange", Output: "V4", Mode: "Switch" }

1. Download

your a mobile application from http://www.blynk.cc/.

2. You should register in Blynk

3. Create a new project

4. Adding the project name

5. Copy your project token

It should fill in the example code on a row:

char AUTH_TOKEN[] = "1234567890abcdef1234567890abcde";

6. Showing the widgets

7. Adding four Button with fallows names: Relay 1, Relay 2, Relay 3 and Relay 4. Set button Mode to Switch

8. The result is followed

9. Adding LCD widget. Set LCD widget to Advanced mode

10. This is the application

11. After you start the ProDino WiFi-ESP WROOM-2 device, on your mobile device you see:

The sketch code

Prerequisites: see example above

Pin maps PRODINo WiFi-ESP -> Blynk:

Relay1 -> V1 {Type: "Button", Name: "Relay 1", Color: "Green", Output: "V1", Mode: "Switch" }
Relay2 -> V2 {Type: "Button", Name: "Relay 2", Color: "Blue", Output: "V2", Mode: "Switch" }
Relay3 -> V3 {Type: "Button", Name: "Relay 3", Color: "LightBlue", Output: "V3", Mode: "Switch" }
Relay4 -> V4 {Type: "Button", Name: "Relay 4", Color: "Orange", Output: "V4", Mode: "Switch" }
OptoIn1 -> V5 {Type: "LED", Name: "In 1", Color: "Green", Input: "V5" }
OptoIn2 -> V6 {Type: "LED", Name: "In 2", Color: "Green", Input: "V6" }
OptoIn3 -> V7 {Type: "LED", Name: "In 3", Color: "Green", Input: "V7" }
OptoIn4 -> V8 {Type: "LED", Name: "In 4", Color: "Green", Input: "V8" }
DHT1T -> V9 {Type: "Value Display", Name: "Temperature", Color: "Green", Input: "V9", Min:"-40", Max:"80", ReadingFrecuency: "5sec" }
DHT1H -> V10 {Type: "Value Display", Name: "Humidity", Color: "Green", Input: "V10", Min:"0", Max:"100", ReadingFrecuency: "5sec" }

1. Create a new project

2. Adding the project name

3. Copy your project token

4. Start the project

5. Showing the widgets

6. Adding four Button with fallows names: Relay 1, Relay 2, Relay 3 and Relay 4 (see example above)

7. Add four LED widgets with names: In 1, In 2, In 3 and In 4

8. Adding two Value display widgets for a Temperature (set input Min from -40 and Max to 80) and a Humidity (set input Min from 0 and Max to 100).

9. This is the application

10. After you start the ProDino WiFi-ESP WROOM-2 device, on your mobile device you see:
