555 tone generator
555 tone generator, a basic 555 squarewave oscillator used to produce a 1 Khz
tone from an 8 ohm speaker. In the circuit on the left, the speaker is isolated
from the oscillator by the NPN medium power transistor which also provides more
current than can be obtained directly from the 555,
