Just a few steps before you start tinkering with your smartphone and Arduino or Raspberry Pi:
1. DOWNLOAD Blynk APP:
2. INSTALL BLYNK LIBRARY
Connect LED to digital pin 7 on your Arduino.
Open the example sketch based on what type of Internet shield you use. If you don't have any shield, try connecting over USB, but please keep in mind, that it can be hard for newbie makers. Check the USB example – all the instructions are inside.
There is a bunch of great examples to get you started. Think of them as LEGO bricks and combine them as you wish. For example, take the Ethernet Shield sketch and combine it with the Servo example, or choose a USB sketch and add a code from GetData example.
3. BUILD YOUR FIRST PROJECT
Open Blynk app. Add Button widget. You can hold and drag it to reposition. Tap once to get to Widget Settings. The main thing you need to set is PIN number you want to control (e.g. if your LED is connected to pin 7 – choose pin D7)
• Paste Auth Token to your sketch and upload it to hardware.
• Press ► in the Blynk App. You are all set!
