This article is programming in Python to drive a robot moving with wheels. VisionRobo car is a robot kit that is equipped with a DC motor that is attached to a wheels gear set. It uses a circuit to drive a DC motor connected to Raspberry Pi Board and connect a USB WebCamera Module and Ultrasonic Sensor Module for image processing and calculate the distance of the robot to the surrounding objects.
This article discusses how to use an ultrasonic module with a Raspberry Pi board (the previous article applies to the ESP8266) in Python to show the distance from the sensor to the closest object found.
This article describes how to use OpenCV to find QRCode from an image from a Web Camera connected to the Raspberry Pi via a USB port. The example contains an example of reading the results from a web camera. And exit the program by pressing the ESC key, the QRCode search example and decoding the text within the image and storing the result in the image file.
This article is an example of python implementation to call a speech-to-text service, then send a message to Google’s text-to-speech service to generate and return an mp3 audio file, and finally, use pygame to play the speech out of the speaker. It runs on the Windows operating system.
This article is an implementation of Python’s Pandas library using the Raspberry Pi 3 B+ board. It can be applied to Python of Windows, macOS or Linux operating systems. The article will be divided into several episodes like the previous ulab library. The article EP 1 discusses Pandas features, installation and data structure of Pandas.
This article is an example of a Python program to calculate the percentage of the occurrences of heads or tails in n flips of a coin.
This article is an application of the ESP32CAM board to perform continuous photo shooting with a fixed interval between shots, known as time-lapse, in Python. By installing the firmware with the integrated camera library for connection to the camera module on the ESP32CAM, programming is simple and easy code configurable.
This article outlines the steps for compiling MicroPython with an ESP32 board with Linux operating systems running on Windows 10 or WSL version 1 or 2 to write the resulting binary files onto the ESP32 board.
This article is a memoir about setting up the Raspberry Pi 3 B+ board as a LAMP-based web service or Linux + Apache + MySQL + PHP. We chose MariaDB instead of MySQL. We have discussed how to install and it was already set up in the previous article.
This article is a quick note of installing MariaDB database management system on the Raspberry Pi board to store and manage data. It creates a unique database for users who can log into the Raspberry Pi’s system.
