Roulette wheel
The main assignment I have done in this unit was called "Roulette Wheel". It was done on a breadboard with 10 LED'S, with a 555 Timer and a 4017 counter chip. The 555 timer chip had 8 pins where as 4017 had 16 pins.The LEDs were connected to 4017 which generated the output so the LEDs would light up in the certain way you wanted. My design was a question bubble, the LEDs would light up in a circular format. In conclusion this assignment was fairly fun, and gave me some great experiences with electrical work.
