A 10-LED chaser that sequentially illuminates LEDs using a CD74HC4017E decade counter with adjustable speed control.
- 10-LED sequential display - Uses a decade counter (CD74HC4017E) to drive 10 LEDs in a sequence
- Adjustable chase speed - Variable timing control via potentiometer for LED sequence speed
- Auto-reset function - Automatically cycles through all 10 outputs continuously
- Single direction chase - LEDs illuminate sequentially from output 1 to 10
- Low-power - CMOS logic for efficient power consumption
- Supply Voltage - 3V to 15V
- Logic Family - CMOS
- Power Consumption - <50mA typical
- Propagation Delay - <100ms typical
- Board Dimensions - 70 x 70 mm

This version had an issue with tracing and my inexperience with using Altium Designer. This led to the LEDs not lighting up sequentially in a clockwise fashion.
