How To Make 3 Channel LED Chaser With Speed Controller || Using NE555 Timer And 4017 Decade Counter

I showed the detailed steps for making an upgradeable high current 3-channel LED chaser light. The design can be upgraded to about 10-channels by simply adding extra transistors (BD139). For higher current output, higher transistor should be used. The enclosure was made using perspex sheet.
