2) Line Follower Robot using Raspberry Pi

With the use of an IR sensor, the Line Follower Robot can track a line. An IR transmitter and receiver are included in this sensor. The light is transmitted by the IR transmitter (IR LED), and the light is received by the receiver (Photodiode). Only if an IR light is reflected by a surface will it return. Whereas all surfaces cannot reflect infrared light, only white surfaces can entirely reflect them, while black surfaces can completely observe them.

Components Required

  • Raspberry Pi (any model)
  • IR Sensor (2Nos)
  • DC Gear Motor (2Nos)
  • L293D Motor Driver
  • Chaises (You can also make one by using cardboards)
  • Power bank (Any available power source)

3) Music Streaming

To begin, you can use the Raspberry Pi to build your own music streaming device. You’ll be able to play Spotify songs after you’ve set it up! This is made possible through Raspotify Connect, a Raspberry Pi OS client that works right out of the box.

After that, you’ll need a speaker to house it once it’s up and running. You can make your own bespoke speaker using 3D printing, but any speaker will do. There are additional software options, such as Pi MusicBox, which has Spotify Connect support. It also has AirPlay and OpenHome capabilities.

Components Required

  • Raspberry Pi Zero W
  • 3” 4-Ω (5-W) speaker

7) Security System

With a Raspberry Pi 4 and camera module, you can keep an eye on your home or business. This project demonstrates how to make a security camera inspired by Portal 2 with 6-mm wide-angle lenses.

This project does not require any programming, according to the creator. Using motionEyeOS, you can make this security camera without writing a single line of code. All you have to do now is write the motionEyeOS image to a microSD card. Then, into the Raspberry Pi, insert the microSD card! There’s also a construction that houses the Raspberry Pi Zero, which is significantly more portable.

Components Required

  • Raspberry Pi 4
  • Raspberry Pi HQ Camera
  • Raspberry Pi 6-mm wide-angle lenses
  • Red LED

8) Optical Character Recognition System

This is another one of the most fascinating projects I’ve ever worked on.

Pi will be used to read the information on boards and recognize characters. This would be extremely beneficial in upcoming projects involving automation and robots.

The Robot might be programmed to read and process data.

To identify characters from images, you’ll use the Google Tesseract-OCR engine in conjunction with OpenCV and Python. You can eliminate noise from images by using the OpenCV library.

Following that, you will be able to decode information from the image using Google Tesseract-OCR and a Python script.

9) Create an IVR System to make Automated Phone calls and send Messages using Raspberry Pi and SIM800L

The Raspberry Pi, as we all know, is a powerful development board that packs a lot of computational power into a little package. This, along with Python’s flexibility, could enable us to create a slew of little devices to solve everyday problems. I recently wanted to develop an IVR system using Raspberry Pi; basically, I needed to use Raspberry Pi to make phone calls and deliver messages, and when the receiver picked up the call, I needed to play a pre-recorded audio and get DTMF inputs as a response. If you’re interested, we’ve also constructed a Raspberry Pi-based Call and Text project, as well as an Automatic Call Answering Machine.

After reviewing the pricing plans for all API-based phone call services, it became evident that using a GSM module like the SIM800L with the Pi and making calls with network service providers like Airtel or Jio is the most cost-effective option.

Components Required

  • Raspberry Pi with the latest version of Buster
  • SIM800L GSM Module
  • 2G SIM Card (Airtel)

  • Perf Board
  • Berg Sticks
  • Connecting wires
  • Soldering Kit

10) Air Quality Monitoring System

The Air Quality Index, or AQI, is used to measure the quality of the air. The thermometer is an instrument that measures temperatures between 0- and 500-degrees Fahrenheit. The AQI, on the other hand, instead of indicating changes in temperature, shows changes in the amount of pollution in the air.

With rising air pollution, we may use Raspberry Pi to create an Advanced Air Quality Monitoring System. The system includes characteristics such as suspended particle matter (SPM), carbon dioxide, ozone, carbon monoxide, smoke, temperature, and humidity to monitor air quality.

Components Required

  • Raspberry pi
  • Bread Board
  • Jumper Wires

11) Arcade Machine

You could buy an arcade machine off the shelf, but a DIY arcade box can be created at home for a fraction of the price with RetroPie and a Raspberry Pi. A Raspberry Pi 3, RetroPie, and a 3D printable housing were used by this builder. On the maker’s Github website, the code and wiring diagram is also available. The instructions also illustrate how to hang the project on the wall.

You may alter the RetroPie theme and even utilize a Scraper to obtain a thumbnail of each game on your build in addition to customizing the hardware. With being stated, it should be noted that Retropie is now fully functional on the Raspberry Pi 4.

Components Required

  • Raspberry Pi 3
  • Jumper Wires
  • Arcade Buttons
