Introduction: This featured Morse Code Practice Oscillator construction project electronically simulates the sound of a Morse code telegraph yet it comes in very cheap single kit pack. In addition, it is equip with a Light Emitting Diode (LED) to simultaneously duplicate the Morse code visually.
Materials: Semi Conductors IC1 – LM555 (Dual-In-Line package) LED1- Light Emitting Diode, Red, Jumbo type Resistors R1 – 560 ohms R2 – 100 ohms

Steps: 1. Check the components required with refer - Once to the part list. Schematic diagram and Parts Placement Guide. 2. Insert and solder the two carbon composition resistors. 3. Insert and solder the 8-pin IC socket into the PCB. 4. Insert and solder the two electrolytic capacitors. 5. Insert and solder the trimmer resistor into the PCB. 6. Insert and solder the Light Emitting Diode (LED). 7. Insert the 9-volt battery clip connecting wires into the 3/16-inch hole located between the loud speaker and battery locations as seen in the Parts Placement Guide. 8. Insert and solder into the PCB one end each of the two insulted connecting wires for the loud speaker. 9. Solder the two loudspeaker connecting wires in to the loudspeaker terminals. 10. With the 9-volt battery removed from the clip insert the 555 Timer IC into its socket. 11. Check all the connection made with xxxx to the schematic diagram. 12. give the rubber footing or the xxxx side of the PCB. With all the connections and mounting procedures carried out correctly, the project is now ready for testing & adjustment!!
Conclusion: Learning Morse Code is not simple study of dots and dashes, Morse Code is a language sound. The characters (letters, figures, and function marks). Must not be learned as a combination of dots and dashes. The sound of the characters should be learned using a Morse Electromagnetic Telegraph that actually sends the characters.
