Raspberry Pi 4

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…

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…

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…

In this tutorial, we are going to implement an Emotion Recognition System or a Facial Expression Recognition System on a Raspberry Pi 4. We are going to apply a pre-trained model to recognize the facial expression of a person from a real-time video stream. The “FER2013” dataset is used to train the model with the help of a VGG-like Convolutional Neural Network (CNN).

In the time of Covid-19, Social-distancing is an effective way to slow down the transmission of infectious virus. People are advised to minimize their contact with each other to minimize the risk of the disease being transmitted through direct contact. Maintaining a safe distance is a challenge for many places like factories, banks, buses or railway stations, etc.

The Raspberry Pi Foundation has announced the immediate availability of the  Raspberry Pi 8GB version of its new Raspberry Pi 4 Boards. Almost a year back when the Raspberry Pi 4 was introduced, the official website mentioned an 8GB version initially, but later removed it citing it as a typo for 4GB. But as Eben Upton, CEO of Raspberry Pi Foundation says it became the “…

Energy Monitors, whether covering the entire apartment or deployed to monitor just one appliance, provide a way for you to keep track of your consumption and make necessary adjustments. While they are increasingly becoming available on the market, the maker in me still feels it will be a great idea to build a DIY version that could be tailored to meet specific personal…
