Components required :
1.5 sensors(LDR )2.Wooden stick
3.Connecting wires
4.Adapter
5.Black tape
6.Screws
7.DC jack
8.In case of 9v battery snap is required
9. buzzers
10.Batteries (5/9 V)
Procedure
1.Take a wooden stick of 80-90 cm and fix 3 sensors at the end of the stick .
2. Fix the remaining 2 sensors on the body stick for left and right detection.
3. Connect all the positive terminal of sensors together( same for negative terminal ) so that only two wires can connect to battery.
4.Output terminals of 3 sensors which are fixed at top are connected altogether to the positive terminal of buzzer 1 and the negative terminals should be connected to the negative terminal of battery.
5. Same connection is repeated for the remaining two sensors to buzzer 2.
5. Supply can be given using battery or adapter. You can vary your sensor's potentiometer according to your requirement.
Now your detector is ready.
