Hello everyone, I made a simple morses decoder with Arduino Pro Mini that displays decoded letters on a 7-segment display. It is a very easy project for beginner like me. It is a mix of "Arduino Morse Code Machine" and "Alphabetic Character display on 7 Segment LED using Arduino".
Step 1: Parts
- 1x Arduino Pro Mini
- 1x Programmer (I used Arduino USB-2-Serial)
- 1x Breadboard
- 8x 150 ohm resistors
- 1x 7-segment indicator SC08-11EWA
- 1x Button
- 2x LEDs
Step 2: Schema
I did not know how to draw other pins, so you need to connect:
Dot LED = 10pin,
Dash LED = 11pin,
Buzzer = 14pin
Step 3: Code
As always, on the top are defined pins, pause_value.
When you press the button for a short time, dot LED lights up. When you press and wait a bit, dash LED lights up.
After you combine dots and dashes the according letter or number lights up on the 7-segment display
