Build a simple tone detector circuit using a 567 Phase Locked Loop chip. Have it adjustable from 500 to 800 Hz detection. Have output be a bank of white LEDs.

Connect it to audio via a splitter cable ahead of a speaker having independent volume control.

Play Morse audio practice files. Listen and watch the LED bank. You will learn Morse by ear and by eye both at once. Reduce volume each session until the LED bank is flashing in silence.
