We all know how important communication is between individuals. Without proper communication, mishaps and misunderstandings will certainly occur.
The continuous innovation on the methods of communication has led us towards computers and mobile phones these days. These are greatly helpful to ensure that we may be able to reach people no matter how far they may be.
So for experiment, we are going to create simple electric messenger.
Materials:
Wooden Base
Small LED light
Small LED light holder or a lamp holder
D Size Battery
D Size Battery Holder
Knife Switch
Glue Gun
Glue Stick
3 Connection Wires
Electrical Tape
Procedure:
- Get your wooden base and attach the knife switch, battery holder and lamp holder on the sides, following the image above.
- Attach the LED light on the lamp holder.
- Attach the battery on the holder.
- Get one connection wire and cut both rubber tips so that the copper will come out. Attach one end of the wire on the battery’s one end and secure it using an electrical tape. The other end must be attached on one of the knife switch’s terminal, preferably the one nearest to your battery.
- Get your second connection wire and again cut both rubber tips so that the copper will come out. Attach one end of the wire on the battery’s other end and secure it once again using an electrical tape. The other end of your connection wire must be connected on the lamp holder’s first terminal, preferably the one nearest to your battery.
- Now, get your third connection wire, cut the rubber tip and attach one end on the remaining lamp holder’s terminal and attach it on the remaining knife switch’s terminal.
- Try to turn the knife switch on and see if the LED light is working.
So basically, this will serve as your electric messenger. We are going to use the Morse code that was invented by Samuel F. B. Morse in 1830s. The initial Morse codes were just numbers so it had to go through a lot of alterations and come up with letters and punctuations so that the messages will be easier to decode and understand. The new technology patented in 1849.
During the World War II, Morse code has been widely used to send a message to people. The message is being sent through sound and light signals. Although much harder to decode compared to an actual message being sent through voice, it has been very helpful during the earlier days when communication methods were very crucial.
So for your electric messenger, we are going to associate it on the Morse code. Kindly check the above image and see the codes parallel to the numbers, letters and punctuations.
So for the dot, you have to turn on and off the switch quickly. For the line, the light must be turned on three times longer compared to the dot. For every letter, a short pause must be done. A longer pause, about three times longer than each letter’s pause, must be done if it will be a new word.
