One of the most commonly used display modules - seven segment displays are important part of many embedded projects. They are used to display numbers and few alphabets. Basically 7 segment displays are combination of 7 different LEDs and we display various numbers and alphabets by glowing LEDs in different combinations. You can read more about 7 segment display units here.
Here we have interfaced a 7 segment display module with AT89S52, a popular 8051 series microcontroller, and created a 0-9 decimal counter. Check out the circuit diagram and code here.
Below is a demonstration video of this decimal counter.
