Required components S.No COMPONENTS Qty 1 TMS320F280025C microcontroller 1 Buy F280025C From Mouser 2 Connection hardware(JTAG,USB) …
The project aims to design an “Exam Room Guide” by which students can be guided for exams based on the confusion system. Radio Frequency Identification (RFID) card readers provide a low-cost solution for reading passive RFID transponder tags up to 2 inches away. RFID card readers can be used in a wide variety of hobby and commercial applications, including access control, automatic identification, robotic navigation, inventory tracking, payment systems, and car immobilization.
Overview In this tutorial, I will let you know how to make your wireless video streaming device in which you can stream that live video on the internet using the ESP32 CAM board and blink IoT platform. Hence, today’s topic is all about making IoT-based Surveillance CCTV Cameras using ESP32 CAM & Blynk cloud. Introduction…
Overview In this tutorial, we will see how to use IWDG (Independent Monitor) and WWDG (Window Monitor) in STM32. Both monitors are used for a similar purpose, but the difference is in their implementation. The main difference between the two is that a standalone watcher can be reset at any time before it times out,…
Real-time clock A real-time clock (RTC) is an electronic device (most often in the form of an integrated circuit) that measures the passage of time. Although the term often refers to the devices in the personal computer, servers and embedded system, RTCs are present in almost any electronic device which needs to keep accurate time. Components Required: STM32F303CB/STM32 blue pill boards –…
Introduction: This article will explore how to establish a Controller Area Network (CAN) communication interface between an Arduino and an MSP432 microcontroller. CAN is a robust and widely used communication protocol in automotive and industrial applications, known for its reliability and real-time capabilities. By implementing CAN communication, we can facilitate data exchange between different microcontrollers…
