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.
The bulbs will be connected in such a way that one Red and one Green can work together as shown in the diagram.
Four of the bulbs will be connected at a joint like this.
From the other end of the bulbs a two way switch will be connected like this.
A wire from the joint, and a from the two way switch will join at the supply source i.e. the battery.
When all things are done one of the pairs of the bulbs will glow.
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.
