3 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.) 1.Ply Board (30 cm sq.) 2. 2 small pole like wood 2. 2 small pole like wood cylindrical in shape. cylindrical in shape. 3. Two-way switch. 3. Two-way switch green bulbs green bulbs red bulbs red bulbs. 6. Tools. 6. Tools.

4 The bulbs will be connected in such a way that one Red and one Green can work together as shown in the diagram.

5 Four of the bulbs will be connected at a joint like this.

6 From the other end of the bulbs a two way switch will be connected like this.

7 A wire from the joint, and a from the two way switch will join at the supply source i.e. the battery.

8 When all things are done one of the pairs of the bulbs will glow.

9 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.
