Data Acquisition System With a CSMA/CD Based Collision Doman Network Using a 32 -bit RISC Core

-
  Introduction Project Overview This LAN-based Data Acquisition System integrates an LPC2126 microcontroller , an LM35 temperature sensor , and various communication protocols to create a system capable of measuring temperature and transmitting the data over a network. The LPC2126 is an ARM7-based microcontroller with several communication peripherals, including UART for serial communication and SPI for high-speed data transfer. The system includes an analog-to-digital converter (ADC) that converts the analog output from the LM35 temperature sensor into a digital signal, which the microcontroller processes. The temperature data is then transmitted to a Linux-based server via UART communication, where it can be displayed and analyzed by clients connected to the network. The system provides real-time data logging and monitoring over a local area network (LAN), which can be used in various domains like industrial automation, environmental monitoring, and smart home applica...

Smart Bluetooth Car with Obstacle Detection

Introduction      The Smart Bluetooth Car is an innovative project that combines the functionalities of Bluetooth communication and sensor-based automation to create a highly responsive and interactive vehicle system. Designed using two Arduino Nano boards, an HC-05 Bluetooth module, four DC motors, and an ultrasonic sensor, this project aims to showcase the potential of embedded systems and robotics in developing autonomous and remotely controlled systems.      The core feature of this smart car is its ability to detect obstacles and take predefined actions without user intervention. When the ultrasonic sensor detects an object, the first Arduino generates a digital signal and transmits it via a serial communication link (TX/RX) to the second Arduino. The second Arduino, upon receiving the signal, activates an interrupt pin to stop the car immediately. The car then reverses slightly to avoid the obstacle and waits for further instructions via Bluet...
