This project is a Digital Clock that displays time in minutes and seconds on a 4-digit 7-segment display. It uses the ATmega32 microcontroller, a BCD to 7-Segment Decoder (IC 7447), and the ...

Security. Find and fix vulnerabilities ...

In engineering circles, this circuit is better known as a 7447 BCD to seven-segment decoder/driver, but just using a single chip has little pedagogical value.

This study presents the design and development of a virtual laboratory for the Logic design course. A novel implementation of a BCD to seven-segment decoder is shown, which allows student to connect ...

Logic 0 will turn on a segment, and logic 1 will turn it off. A lookup table in the MCU code is used to generate the desired display. U4 can be two sections of a 74HC14 or one 74LVC2G14/NC7WZ14.
