49. IoT - First step towards Home automation

Hey everyone!
Today I am going to teach you about Internet of Things (IoT). This is my first IoT project and the first step towards home automation. Using IoT, interrelated computing devices are able to transfer data over a network without requiring human-to-human or human-to-computer interaction. In this page, you will see how I controlled my pedestal fan and soldering station with my smartphone.

Hardware components used in this project

  • Arduino Uno
  • Ethernet Shield W5100
  • Relay module (x2) - 5V single channel
  • Female-to-Male Jumper wires (x3) - 20cm
  • Male-to-Male Jumper wires (x3) - 70cm
  • Male header pins - 3 pins
  • Female header pins - 3 pins
  • Plug extension
  • Wire (x2) - 10 cm
  • Ethernet cable
  • Wifi router
  • Smartphone/ Tablet

Software apps

  • Arduino IDE
  • Blynk app 

Setup


Your setup must look somewhat similar to those in the pictures above.

Connections

Relay module 01 (Soldering station) - 5V single channel

  • S - D2
  • (+) - 5V
  • (-) - Ground (GND)

Relay module 02 (Fan) - 5V single channel

  • S - D3
  • (+) - 5V
  • (-) - Ground (GND)

Coding

You will be needing Blynk app for this IoT project. If you are new to Blynk, please feel free to follow the hyperlink. If your smartphone or tablet uses the Android OS, you can install Blynk app in playstore. Blynk app only works in iOS and android.  Follow the steps given in this page (https://blynk.io/en/getting-started) to successfully work with Blynk.
Open Example Code Builder, choose your hardware model and connection type. Within Examples, choose Blynk Blink option and copy the whole code to buffer. Add your Auth Token in the codes. The Auth token will be sent to your email address. Upload the code to your Arduino Uno.
Open Blynk App and tap PLAY. Wait till you see the message that your device is connected and online.
Now, you can control the electronic devices which you connect to the plug extension.
Happy Blynking!
If anyone has any questions with the coding, please feel free to comment below or send me an email at arduinoprojectsbyr@gmail.com.

Final Look

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 - A4 SCL - A5
