The HEF4543B is a BCD to 7-segment latch/decoder/driver for liquid crystal and LED displays. It has four address inputs (D0 to D3), an active LOW latch enable input (LE), an active HIGH blanking input ...

In this project, time is calculated in minutes and seconds and displayed on the 7-segment display. The ATmega32 generates BCD values for each digit, which are then sent to the BCD to 7-Segment Decoder ...

Abstract: Now-a-days majority of practical applications such as valet car parking, larger temples necessitate, seven segment displays to give a visual token of the numbers. Digital counters are the ...

This project demonstrates how to interface a keypad and a 7-segment display with a PIC16F887 microcontroller. The circuit is designed using Proteus ISIS, and the code is written in mikroC. A visual ...

[spencerhamblin] is starting his explorations into digital electronics the hard way: reproducing a “simple” IC’s functionality by wiring up a board full of discrete transistors. In this case, the end ...

Even if you are designing a microcontroller-based LED display system, often it may calls for a manual option to control brightness of the LED display unit. On the otherhand, if it is based on discrete ...
