Now that you have created a new account with Blynk Cloud and logged in to your Blynk app builder running on your smartphone or tablet, you can follow the following steps to create a new project with the Blynk app builder:
- To start building a project, tap New Project. This will bring you to the create New Project wizard:
Creating a new project
- Type in demo in the Project Name textbox:
Creating new project—project name
- Tap the CHOOSE DEVICE dropdown box to see the available hardware models (the default is ESP8266). Then, tap Raspberry Pi3 B from the Select your hardware list. You may find other versions of the Raspberry Pi as well. Following are the available options for Raspberry Pi versions:
- Raspberry Pi 2/A+/B+
- Raspberry Pi 3 B
- Raspberry Pi A/B (Rev2)
- Raspberry Pi B (Rev 1)
- After choosing the hardware model, tap OK:
Creating new project—Selecting hardware
- Tap on the CONNECTION TYPE dropdown list to see the available connection types. Then select WiFi from the CONNECTION TYPE list, followed by OK.
- Tap the Create button to create the project workspace:
Creating new project
- After successfully creating the project, the app builder will send an auth
token to confirm your project. Every new project you create will have its
own auth token. The auth token is a unique identifier that consists of alphanumeric characters, and authorizes you to access the Blynk Cloud,
located at https://www.blynk.cc/:
Notification about the auth token
- At the same time, you'll have an auth token automatically sent to the email address you provided.
If you have lost your auth token, you can still find it with your project in Project Settings (the nut icon).
- Tap the nut icon in the toolbar to get to the Project Settings page. Then, scroll down to find the DEVICES section. Tap demo Raspberry Pi 3 B (WiFi).
- Alternatively, you can tap Email all under AUTH TOKENS to get all the Auth tokens on your email provided for each project in your Blynk account. You can also tap Copy all to copy all the Auth tokens to your mobile device's clipboard:

You will learn how to use the Auth token with your C++ code later in this chapter.
