Raspberry Pi is a powerful palm-sized pocket computer based on the ARM Cortex architecture. With its high operating speed, memory, and wireless capabilities, electronics engineers and makers use it for a variety of applications, including home automation, the Internet of Things (IoT), Artificial Intelligence, Machine learning, and computer vision. If you are new and looking for interesting Raspberry Pi projects for beginners, this collection is a great place to start with basic components such as LEDs, sensors, buzzers, relays, and push buttons. Our hub also consists of good Raspberry Pi projects using Raspberry Pi 2, Raspberry Pi 3 and Raspberry Pi 4, ranging from basic projects to advanced industrial projects. Whether you are a student, hobbyist, electronics enthusiast, or a beginner, CircuitDigest's collection brings together innovative Raspberry Pi-based projects that match your interests and technical skills.
If you are looking for projects from other development boards of Raspberry Pi, you can check out our Raspberry Pi Zero Projects and Raspberry Pi Pico Projects.
Getting started with Raspberry Pi is a great way to learn programming. Here are some interesting ideas for Raspberry Pi projects that demonstrate how this small computer can be used in practical applications.
Today, in this project we are going to build a Smart Shopping cart by interfacing a thermal receipt printer, LCD, and a USB barcode scanner with Raspberry Pi. This Smart Shopping cart will scan an item’s Barcode, display its information on 20x4 LCD, create the invoice, and print it using a Point of Service (POS) Thermal Printer. We will be using a Google…
Self-driving cars are one of the modern world's newest fads. These self-driving cars rely on highly advanced control systems, sensors, actuators, complex algorithms, machine learning systems, and powerful processors. Road lane detection is one of the important things in a self-driving car as it helps the car to keep driving in between the lines. As we all know,…
When we talk about interfacing displays with microcontrollers for an embedded project, alpha numeric Liquid Crystal Displays (LCD) are the most commonly used displays which are usually based on Hitachi HD44780 Driver. They are low powered, robust LCDs that are capable of displaying various characters in 5X8 or 8X10 pixel matrix. In this article, we will be interfacing an…
Barcode Scanner has the capability of scanning various types of linear barcodes. Mostly barcode scanners are used in shopping centers, food supply chains, restaurants, Clothing Stores, etc. Nowadays barcode scanners are being used in smart shopping carts as they provide fast and failsafe item recognition. In this article we will be learning how the output of the Barcode…
In this project, we are going to build a Lane Detection Car using Raspberry Pi and OpenCV. Before proceeding with this project, make sure that you have a basic idea of how to use OpenCV using python in Raspberry Pi. The lane detection problem is typically framed as a semantic or instance segmentation problem to identify the pixels that belong to the lane class. We need…
Alexa is the language assistant launched by Amazon in 2014 and used, for example, in smart speakers such as the Amazon Echo or the Echo Mark. Alexa serves as a central control unit in these devices which respond to the user's voice commands. For example, you can download songs from Amazon Music or Spotify, play audiobooks from Audible, and get news and weather updates. Even the program can…
Ever wondered why do you need Node-RED with Home Assistant? It looks like that both Home Assistant and Node-RED do the same things but they excel in different areas. Home Assistant’s main power is its ability to interface and control any smart device existing at the moment. The main method of creating automation in Home Assistant is by using…
Human pose estimation technology is becoming increasingly popular due to the recent growth and popularity of Virtual and Augmented Reality. In our previous tutorial, we used Media pipe Hand Tracking module to control Raspberry Pi media player using hand gestures. In this project, we are going to use the MediaPipe Pose estimation package to build a push up counter. We will be…
With the Internet of Things taking over the lives, home automation is becoming more and more common. Home automation can include the scheduling and automatic operation of lighting, heating, cooling, window blinds, security systems, and other devices. There are many home automations platforms available that allow vital home functions to be controlled remotely from anywhere in…
Security has always been a major concern for mankind. Today we have video surveillance cameras in schools, hospitals and every other public place to make us feel secured. According to a survey by HIS it is estimated that there were around 245 million security cameras installed and functioning back on 2014, which is like having one security camera for every 30 people on this…
OpenCV is a powerful tool and that combined with Raspberry Pi can open doors to many portable smart devices. In our previous Raspberry Pi CCTV monitoring article, we learned how to get live CCTV video from a DVR using RTSP and display on a Raspberry Pi, do check that out before proceeding. In this article, we will learn how to leverage the power of OpenCV and build a…
Hand gesture recognition technology is becoming increasingly popular due to the recent growth and popularity of Virtual and Augmented Reality technologies. In our previous tutorial, we trained a Hand Gesture recognition model to play Rock Paper and Scissors with Raspberry Pi using Tensorflow and Keras. In this tutorial, we are going to use the MediaPipe Python library to…
