Building and Programming Your PiCar-X: A guide to getting started with your robot car using EzBlock programming language. Learn how to assemble the parts, program your PiCar-X using drag-and-drop blocks, 3D print a simple LED holder to add lights to your car, and create a blink example. Also, learn how to use a button to turn the LEDs on and off, as well as control the camera.
This latest article in the series explores how to use the BNO055 sensor with ESP32, ESP8266, and Arduino to achieve gyroscope high rate and any motion interrupt. The BNO055 sensor combines an accelerometer, magnetometer, and gyroscope in one module, making it ideal for accurate orientation tracking.
Continue the series of article about the Bosch sensor BNO055. In this part of the tutorial, we will learn how to enable the INT pin of the BNO055 and configure the accelerometer High G Interrupt. The High G Interrupt is triggered when the accelerometer detects a sudden acceleration event that exceeds a specified threshold and duration. This can be useful for detecting impacts, falls, or other sudden movements in a variety of applications.
This article discusses how the ESP32 can perform self-OTA updates of its firmware from a server, allowing you to remotely update the firmware of an ESP32-based device without having to physically access the device. To do this, you need to set up a server that hosts the new firmware image and add OTA support to your ESP32 firmware. By implementing self-OTA updates, you can ensure your devices are running the latest firmware without having to physically access them.
This tutorial explores how to implement OTA updates on an ESP32 using a web browser as a custom interface. We will create a custom web interface using HTML and JavaScript to upload firmware files to the ESP32, and then use the ESP32’s OTA update feature to install the new firmware. By the end of this tutorial, you should have a solid understanding of how to use OTA updates to keep your ESP32 devices up-to-date with the latest firmware.
In this article, we will explore how to perform OTA updates on the ESP32 using a web browser and HTTPS protocol with a self-signed certificate. HTTPS provides a secure way to transfer data over the internet and is essential for any OTA update process that involves sensitive information. A self-signed certificate can be used to provide encryption and authentication without the need for a third-party certificate authority, making it a cost-effective solution for small-scale projects. By the end of this article, you will have a working OTA update process for your ESP32 project that uses HTTPS protocol and a self-signed certificate.
