2 The circuit shows working model of two way traffic light system . The project or model prepared with 4 light bulbs, 2red and 2green.The source is a battery of 3volts.The items required to make the model are :-1.Ply Board (30 cm sq.)2. 2 small pole like woodcylindrical in shape.3. Two-way switch.4. 2 green bulbs.5. 2 red bulbs.6. Tools.
3 The bulbs will be connected in such a way that one Red and one Green can work together as shown in the diagram.
4 Four of the bulbs will be connected at a joint like this.
5 From the other end of the bulbs a two way switch will be connected like this.
6 A wire from the joint , and a from the two way switch will join at the supply source i.e. the battery.
7 When all things are done one of the pairs of the bulbs will glow.
8 This circuit can be used on a two side traffic pole This circuit can be used on a two side traffic pole. To switch the circuit completely off from another switch would be required.THIS PROJECT PREPARED BY ME UNDER ELECTRO SCIENCE CLUB ACTIVITY.
