Introduction: Control Raspberry 2 GPIOs by a Beautiful WebApp Within 10 Minutes
This simple Tutorial shows you how to control the GPIOs of your Raspberry 2 through a beautiful WebApp, using the guhIO IoT software.
You only need your Raspberry set (SD card + power cable + network cable).
Step 1: Download Required Software
Take an SD card of minimum 4GB you can overwrite. Consider your data is going to be erased!
- Download the operating system for your Raspberry. Everything you need is preinstalled.
- Download the SD Formatter for your Windows or Mac computer.
- Download and install this great SD Flash tool etcher for your computer.
If you prefer to continue on an existing Raspberry installation, head on to this tutorial (valid for Debian/Raspbian Jessie 8.0 and higher).
Step 2: Format SD Card
- Insert SD card into your computer.
- Make sure you don't have important files on the SD!
- Install and open the SDFormatter tool from Downloads.
- Just keep standard settings and click Format.
Step 3: Flash SD Card
- Install and open the Etcher SD Flasher tool from your Downloads folder.
- Klick Select image and choose the xxxx-xx-xx-guh-ubuntu-xx.xx-armhf-raspberry-pi-2.zip file from your Downloads folder.

- Have a tea.
Step 4: Boot
- Insert the SD into the Raspberry.
- Connect it to your LAN with an Ethernet cable.
- Connect the power cable.
- Watch the LEDs if they blink - you did a perfect job!
Wait for two minutes.
Step 5: Open the Interface
And now comes the big moment!
