Servo Motor Control Using Raspberry Pi and BLYNK APP

In this tutorial, we will learn how to interface Servo motor with the Raspberry pi module and operate it with the Blynk app. and  This project I will try to show you very easy and beautiful step-by-step. If you start this project with me then I believe you can complete it too. It is a very simple process. Below is a list of all the components you need to complete this project

I will try to give you a brief idea about the components required for this project. If you want to know more about this vibration, you can find out by searching on Google.

Raspberry pi

The Raspberry Pi is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. It is a capable little device that enables people of all ages to explore computing and to learn how to program in languages like Scratch and Python. It’s capable of doing everything you’d expect a desktop computer to do, from browsing the internet and playing high-definition video, to making spreadsheets, word-processing, and playing games. What’s more, the Raspberry Pi has the ability to interact with the outside world and has been used in a wide array of digital maker projects, from music machines and parent detectors to weather stations and tweeting birdhouses with infra-red cameras. We want to see the Raspberry Pi being used by kids all over the world to learn to program and understand how computers work. Source: What is a Raspberry Pi?

Servo Motor:

BLYNK account

First, you need to download Blink Apa from Google Play Store and open it and create an account with an email and password. Here you need to create an account with an email address and password. What else is an account? When you log in, you will see an interface like this flow in this video. [caption id="attachment_385" align="alignnone" width="136"] how to create blynk account[/caption] Now an email has been sent to your email account This is very important because you need to interface the Blink app with Raspberry Pi.  using this key while programming. so you need to save the key, otherwise, the program will not work.

    while True:
        blynk.run()

except KeyboardInterrupt:
    print("Quit")

# Reset GPIO settings
