Here we design a simple display decoder circuit using logic gates. Even though commercial BCD to 7 segment decoders are available, designing a display decoder using logic gates may prove to be ...

The main objective of this report is to understand and design circuits with designing steps. Additionally, research about the seven-segment display and counters. Each of the decimal numbers (from 0 to ...

In this post, two LED blinking circuits are given below. First one is dancing bi-color LEDs (two different color LEDs) where the two color LED will run in sequence. In the second circuit, we will ...

parts list, circuit diagram & testing or you can continue reading the post for further details. A simple LED chaser hobby circuit can be made using 555 timer and CD4017 counter IC. You can use this ...

This circuit make an LED blink for every half second, and the square wave output of 555 IC is connected to a BINARY counter of 8bit (74HC4040). Each time when a pulse is generated by timer, binary ...
