Hi I need some help on building a traffic light circuit. Below I have drawn a schematic diagram and I am unsure if it's correct or not. I have builded this on a breadboard using three AND gates (74LS08), 1 OR GATE (74LS32P), a INVERTER (74LS14N) 555 timer chip and a counter chip (74LS193N). This is runned by volts, by having a regulator already setup and working. The 555 timer chip is included with two 470K resistor and one 100 uF capictor. The objective of this circuit is the opposite of the traffic lights will turn on, for example if red north south is on then east west green will turn on etc. The A2, B3, C6 and D7 on the diagram is the counter chip. Please let me know if I had drawn this diagram correct! Thank you!
