i need help with the design of a traffic controller light, the project has to be configured using discrete logic, as micro-controllers cannot be used. the only integrated circuit to be used are op-amps. the circuit must be operated from a supply that converts 240V ac to 5V dc @ 200mA. the switching of the lights is controlled by a digital logic circuit at 5V dc voltage.
any correspondance regarding the above question will be greatly appreciated. [/url]
