Hey Guys I already Have This Project Simulated. How Can I Add A Counter Describe Below:
1. Yellow light Should Be 10 Seconds.
2. Green Light Should Be 30 seconds on the "Solo"
3. Green Light Should Be 45 seconds on secondary avenue.
4. Green light Should be 1 minute on principal avenue.
5. When the Yellow light finish their period, all the lights turn to red for 2 seconds.
Attached the multisim file!
I already try a counter and I failed... I am using a 74LS190N
Here is the equations:
(Principal Green)(PV): A' * C' * D'
(All Yellow)Ay): B * C' * D' + B * C * D + A * C'* D' + A' * B' * C' * D
(Seconday Green)(SG): B * C * D'
(All Red)(TR): B * C' * D + A * C' * D' + A * C * D + A' * B' * C * D'
(Only Way Green) (SoloV): A * C' * D + A' * B' * C * D
Attached the simulation...
Help and example would be veeeery appreciated.
