65. Controlling VLC Media Player with Blynk - Using Arduino and Python

Hello Everyone!
I have explained you about controlling the VLC media player by your hands and IR remote. In this version, I will be using my Blynk app to control my VLC Media Player over long distance. Unlike the previous two versions, this will be an IoT project but the coding will be similar to the previous project.
  • Version 01 - Using Hands: 
https://arduinoprojectsbyr.blogspot.com/2020/02/61-controlling-vlc-media-player-with.html
  • Version 02 - IR remote: 
https://arduinoprojectsbyr.blogspot.com/2020/02/62-controlling-vlc-media-player-with-ir.html

Hardware components used in this project

  • NodeMCU devkit V1.0
  • USB Type A to micro B cable 
  • Solderless Breadboard - Half+ (Optional)

Apps used in this project

  • Arduino IDE
  • Blynk

Setup


Coding

Arduino

The coding will be similar to that of the previous project.
You will need to install the Blynk app and its library; if you are new, please feel free to visit this website:
After you have installed the Blynk app, you will need an account to log in. You can log in using either your Google or Facebook account. Create a new project and name it as 'VLC Media Player'. Select board type as NodeMCU and connection type as WiFi. The auth token will be sent to your email address.
Initially you will be given an Energy Balance of 2000 credits. You have to add 10 button widgets to your project and name them like the following:
  • Play/ Pause
  • Stop
  • Toggle/ Untoggle
  • Volume Up
  • Mute/ Unmute
  • Volume Down
  • Next
  • Previous
  • Fast forward
  • Rewind
Assign each button to the digital pins of your NodeMCU microcontroller board. Open the Example code builder and select the Board and connection type as NodeMCU and ESP8266 WiFi respectively. Select Blynk Blink from the Examples drop down menu. 
Copy the code from the Example code builder and paste it into your Arduino IDE sketch. Add your WiFi credentials and include the auth token that was sent to your email address.
Within your void loop( ), below Blynk.run( ) function you must include these lines of codes:
if (digitalRead(16)==HIGH){
    Serial.println("Play/Pause");
    delay(500);
  }
You can find this pinout diagram useful to prepare the codes. You should use GPIO numbers in order to use the digital pins of the NodeMCU. For example, in the code snippet above, the Play/ Pause button is assigned to D0 but in the coding we have used 16 instead of 0, because 16 is the GPIO number for D0.
Repeat this for the other buttons as well.

Python

Follow the guide in my previous version coding section for this:
If anyone has any questions with the coding, please feel free to send me an email at arduinoprojectsbyr@gmail.com.

51. Buzz wire game using Arduino

Hello everyone! This is my first Arduino project in 2020 and it is going to be a fun and simple project. You would have heard of the Buzz Wire, a steady hand game, and today you will be learning to make one using Arduino. Hardware components used in this project Arduino Nano USB Type A to mini B cable (for Arduino Nano) Solderless Breadboard - Mini and Full-size LEDs (x2) - Green and Red Resistors (x2) - 220 Ω  Active Buzzer module (KY-012) LCD display module with I2C interface - 16x2 Male-to-Male Jumper wires (x4) - 10cm Female-to-Male Jumper wires (x5) - 20 cm Jumpers (x5) - to reduce the usage of wires Copper wire  Tape (or any form of insulation)  Setup Your hardware setup must look somewhat similar to the ones in the images above. The beginning and end of the copper wire maze must be taped to prevent conductivity between the wire loop and maze. Connections LCD display module with I2C interface GND - Ground VCC - 5V SDA -...
