Morse Decoding and Transmission Machine

In this tutorial we see how we can make a morse code decoding machine with wireless transmission of characters.

1.2xArduino Nano boards

2.2x NRF24L01 wireless module

3.2xoled 64x128 I2C display

4.Buzzer module

5.switch button

5 led green and red

6.breadboard and jumper wires

7.Visuino software

Make the connections of the components according to the diagram below

In this stage, we make the connections from the diagram, both for the receiver and the transmitter part. As I stated in the connection diagram, some components are optional. The scheme of the receiver is identical to that of the transmitter, the switch button, the buzzer module and the LEDs are optional for the receiver part.

In this stage we start the Visuino software and run the code. We do this operation for the transmitter as well as for the receiver. Find the attached codes in Visuino format as well as in INO (''C'') format. In Visuino you can see the 28 'CHAR' values, one value for each letter of the alphabet. If you look closely, you can also see the decoding algorithm through logical AND gates. You can try adding the morse code digits, it's worth a try.

In this stage we power up the receiver and type letters on the pushbutton. The device must recognize the line and the point. We also feed the transmitter. and what appears on the receiver's screen must also appear on its screen. I hope you liked my project, if you have any questions you can put them in the comments section. Good luck everyone!
