this is a cool mudkip themed led chaser built using a ne555 timer and cd4017 decade counter. the 555 is configured in astable mode to generate clock pulses, and the 4017 drives 10 leds one by one to create a smooth chasing effect. the pcb outline is shaped like mudkip, and the leds are placed along the body to make the animation flow across the board. the design uses through hole components and a 2 layer pcb with a ground plane for clean routing and stability.
