Equipment: Power supply set to 5V (or use Arduino voltage output) racterspaca-9 Cremen space wordr- Oscilloscope to read your SOS pulse timing DMM to check voltages The basic element of Morse code is the dot and all other elements can be defined in terms of multiples of the dot length The word PARIS is used because this is the length of a typical word in English plain text, it has a total length of 60 dot lengths. If the word PARIS can be sent ten times in minute using normal Morse code timing then the code speed is 10 WPM The character speed is related to dot length in seconds by the following formula Speed (WPM)-24 (Dots per second) Reference docs: AVR datasheet AVR instruction manual UNO or NANO schematic. Here are the ratios for the other code elements Dash length Oot length x3 Dot length Dot length x3 Dot lengthx7 Pause between elements Pause between characters Pause between words (see note) Starting program Previous Blink Sketch from Lab 2. Note: For learning the code this ratio is often increased so that overal lext speed is lower than in standard Morse code. This stretched code is caled Famsworth code. . Flow chart program on-line used from previous lab. www.draw.io Morse code specs See the document defining the timing relationships and follow these rules when designing your program for the SOS Morse Code Program operation: 1) When the switch is held the LED will blink Sos sos SOs etc. until the switch is released. The switch can be a jumper wire since we do not have any switches besides DIP switches. There will be a register assigned for each of the timing values for dot, dash, pause between elements, pause between characters, and pause between words (treat SOS as a word). The registers that you setup will be moved to R16 before you call the subroutine 2) Equipment: Power supply set to 5V (or use Arduino voltage output) racterspaca-9 Cremen space wordr- Oscilloscope to read your SOS pulse timing DMM to check voltages The basic element of Morse code is the dot and all other elements can be defined in terms of multiples of the dot length The word PARIS is used because this is the length of a typical word in English plain text, it has a total length of 60 dot lengths.
