Interface a uC to PC RS232 with MAX232A circuit

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...

interafce 16x2 lcd with avr

LCDs are available in various configurations, with the 16x2 matrix display being the most popular. This article demonstrates the interfacing of an ATmega16 microcontroller with an LCD by displaying a simple character. In this project, the LCD operates in 8-bit...

Interfacing seven segment to microcontroller

The Tutorial shows how to interface 7-segment display to a microcontroller. Also explains how do display more than one 7-segment on same data lines using scanning method. 7 Seg displays are are basically 7 LED's. It will be much easier...

Microcontroller Voltmeter / Ammeter with LCD

The rectifier bridge voltage is determined by the U2 element; refer to its datasheet for the maximum voltage specifications. The minimum voltage at this pin should not fall below approximately 9V, or 6.5V if low-dropout type U2 and U3 voltage...

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...

TV remote controlled computer mouse (an avr VUSB project)

While lying in bed and watching movies on a laptop, the idea arose that having a remote control would simplify the tasks of pausing, playing, fast forwarding, rewinding, adjusting volume, and playing the next track without needing to approach the...

USB Fuse

Life in the 21st century would be almost unbearable without some of the computer peripherals that PC users now look upon as essentials, such as keyboards, mice, and printers. Computer peripherals play a crucial role in enhancing the functionality and usability...

Water Level controller

The microcontroller-based water level controller and motor protector manages the on and off states of the motor based on the water level in the overhead tank (OHT). It regulates the tank's water level through a microcontroller, thereby providing automatic protection...

FT232 USB to Serial Module

This project utilizes the FT232XX chip series, which functions as a USB to serial converter. These chips are capable of converting USB protocol into asynchronous serial protocol, effectively allowing the transformation of a USB1 port into a corresponding serial port....
