The LED-based running display creates an eye-catching running display effect using LEDs. It can be used to light up borders of animations, pictures, etc, and also for short word displays. In this project, we have used some simple components like 555 timing IC, Decade Counter IC CD4017, and transistors.
The kit-led-based running display uses IC NE555 and a popular decade counter IC CD4017. This display consists of 16 LEDs of four layers. The NE555 is wired as an astable multivibrator whose output triggers the CD4017 counter. On powering up the circuit, the timer starts to oscillate to produce triggering pulses. These pulses trigger counters IC 4017 and it counts from 0 to 5. These outputs are fed to general purpose NPN transistors BC547 which are used as current drivers for each led layer. As each of the counter outputs goes high, the corresponding led layer glows sequentially. After it counts up to 4 values it resets to zero and the process repeats.
