Here is my friend's project about traffic light.
The 5-bit counter using 74LS163 worked well since we can see the 5 LED indicated.
BUt when deal with 3 types of light (RED: 25s, Yellow: 2s, Green: 5s), the problem comes since the RED light suddenly blink.
I helped him to check the K-map n circuit but still can find the problem.
So, I post it here n would like to ask from your suggestions.
Thank you.
