Roulette (Tracer) LED Project
Using the 555 timer chip and the 4017 Decade Counter chip, we needed created to a sketch or a design of how our LEDs will flash and in what sequence. We also needed to calculate the second resistor, to control the frequency of the 555 timer chip. The way the LEDs are wired to the 4017 Decade Counter Chip determines the sequence of the LEDs flashing and it resets form the beginning continuously.
