Here is a simple circuitry which will help you to understand how will you interface and LED with a micro-controller. The code is written to turn on and off the LED after some short delay, this is one of the beginning circuit when one tries to gain some hands on …

Sample and Hold Sample and hold circuit is the first step in the process of analog to digital conversion. It actually takes samples of the analog signal at specific time intervals depending on the clock frequency. Clock frequency is the frequency at which we are taking samples of the analog …

Introduction Here we are designing and implementing the four way traffic control system using  TTL logic. There are different variations of traffic control. The most common ones that are seen are signs (board), road lines, islands (division between opposite lanes of vehicles), and traffic lights. The first one mentioned is …

Overview Abstract: To develop  DIGITAL CLOCK using 7 segment display. It show hours and  minutes. Make it by using discrete components. Introduction: A digital clock is a type of clock that displays the time digitally. Digital clocks are often associated with electronic drives, but the “digital” description refers only to …

Summary: With this circuit we interface the serial port to the Microcontroller through which we display up to 32 characters which are input through serial port of the computer. The data we send through the serial port is displayed on the LCD. The data to the RS232 connector is through …

Abstract: This is a simple project of making a digital clock using microcontroller AT89S51. The clock is in 12 hour format with am and pm function. The time is displayed on 2*16 character LCD. Datasheets: AT89S51 Working Video: The link for project files is given below Download attachment

Abstract: The purpose of this project is to implement a simplified version of a robotic arm. This arm uses three motors: one to control the horizontal rotation (about z-axis) of the arm, second and third to control the vertical rotation (up & down movement). Servo motors are used in robotics …

A simple project of digital code lock system. The basic user lock is of 5 Digits and Master Lock is of 10 digits so its not easy for an intruder to break the lock unless you keep the code simple. The input is taken from a 4×3 Keypad (please see …
