Take to another level by attaching a speaker to a PWM peripheral, now you can debug by ear, whilst driving your colleagues barmy with the beeps. The only tricky bit is working out if it was three beeps and a boop, or two beeps then a beep-boop.
More fun to vary the pitch and length of the beep rather than the number of beeps.
