How to control the Raspberry Pi with your smartphone?

A Raspberry Pi is versatile and can be used to control lights or open locks, among other things. But if you don't want to do this via NFC, but prefer to do it via your smartphone, it's easy.

1. Install the app Blynk on your phone, with this you can control the input-output pins on your Raspberry Pi.
2. In order for the app to control the Pi, the first thing you need to do is enable VNC. To do this, simply go to the "Raspberry Pi Configuration" and there to the "Interfaces" tab. Here you activate VNC.
3. Click on the VNC logo at the bottom right of the taskbar and log in with an account or create a new account.
4. Now you can also log in to the VNC server via your smartphone and control the interface of the Raspberry Pi with your phone.
5. Blynk offers you ready-made functions for this, which you can use to control certain pins individually. Richten Sie sich einen eigenen Button ein, der den Output am Pin 0 an- oder ausschaltet, um etwas zu öffnen oder zu schließen.
