Information about project are searching again and the circuit that had been use for this project are searching. For the first the information about the project where the main components for this project is light emitting diode (LED) and from here the details about the LED need be searches for examples the brightness of LED, the lifespan and etc. For the second components are sensor and infrared sensor will used in this project and the function of sensor is to detect the vehicles. Information for circuits not much that can been search because there has no project about street lighting system had been done before this.
