8052 BASIC Project circuit | Next Electronics

The Skeyeball project is an ongoing initiative within the Indiana University System Design Methods Laboratory, aimed at providing graduate and undergraduate students with opportunities to engage in embedded system design and implement various projects. The downlink segment of the project...

Low Resource Microcontroller 3 Phase BLDC Motor Speed Controller

This article discusses a minimal resource microcontroller implementation for a three-phase Brushless DC (BLDC) motor, focusing on a closed-loop speed motor controller application based on a Microchip PIC12 device. It demonstrates how minimization techniques can reduce the number of I/O...

MICROCONTROLLER BASED AUTOMATIC ROOM LIGHT CONTROLLER

This project involves an automatic room light controller with a bidirectional visitor counter using a microcontroller. It is designed to manage room lighting and accurately count the number of individuals present. When a person enters the room, the counter increments...

measurement conductance cell constant

A small transmitter board interfaces with a microcontroller and conductivity probe to measure liquid conductance and conductivity. Precise equations and measurements are provided for this microcontroller-controlled conductivity meter. The described circuit consists of a compact transmitter board that serves as an...

knight Rider

A light computer has been developed that simulates the scanning effect seen in the KITT car from the TV series Knight Rider. The design utilizes a microcontroller, specifically the PIC16F84A, instead of the commonly used CD4017 counter IC. This choice...

synchronizing fireflies ng

This is a remake of the fireflies project that was created a year ago. The concept revolves around the emergence of patterns, particularly the synchronization of hundreds or thousands of fireflies. Initially, they flash randomly, but over time, influenced by...

Automatic Switch Project

Model railroad turnouts, often referred to as switches, can be controlled in various ways. The simplest method is manual control, operated by hand. Remote activation is typically achieved through pneumatic (air) or electrical means. The project discussed in these articles...

Interface a uC to PC RS232 with MAX232A

This document outlines the standard configuration for interfacing a microcontroller, such as the 8051, with a PC using RS232 through the MAX232A. The UART or serial port was absent in the 8049 and 8749 microcontrollers, which were predecessors to the...

Flashflex Microcontroller Control Of Character Lcd Module

The FM497 is an integrated electronic ignition controller designed for breakerless ignition systems that utilize Hall effect sensors. This device operates an external NPN Darlington transistor to manage the coil current, thereby delivering the necessary stored energy while maintaining low...
