555 Timer Morse Keyer

So what does the Morse Keyer do? It takes your input from the switch and makes sounds on the speaker like you would be able to hear on the other end. What is this useful for? The short answer is nothing, it makes funny noise. The speaker is inches away form the switch and any practicing you could do with it can also just be done with your figure and literally any surface. The only way to make it useful at all is if you wanted to extend the speaker to somewhere else, and even then phones exist.

Morse Keyer components: (Wire, Resisters 3.3k and 15k, capacitors 10uF and 47nF, battery, speaker, switch (single tap))

after the trigger has been hit you complete the circuit causing the capacitors to charge and discharge sending the current through the 555 timer to where the Flip Flop, and the amplifiers and make an alternating current that allows the speaker to give off a frequency though the speaker that is then audible.

As stated before, the Morse code keyer does not hove much practical use so a question someone might wonder is why I would choose this project. For the most part it is just because I thought it was cool. I always thought it would be cool to learn morse code but never got around to doing it. I also am a big fan of old war films and a lot of them that are about the civil war era and even world war 1 use morse code.

1. start by attaching your positive power supply to your button.

2. attach your button to plot 4 (Reset)

3. attach 4 to 8 (Vcc Supply)

4. attach 8 to 7 (Discharge) using a 3.3K Ohm resistor

5. attach 7 to 6 (threshold) using 15K Ohm resistor

6. attach 6 to 2 (Trigger)

7. attach 2 to 1 (ground) using 47nf capacitor

8. attach 1 to 3 (output) using speaker and then 10uf capacitor

9. finally attach 1 to your negative power supply / ground

10. Press button and annoy everyone
