Step 11Step 2g: lead bending & soldering - speaker
Connect the speaker's leads to the emitter of transistor Q1 and to the ground at pin 14 of the DIP socket. The speaker probably came with insulated leads but if it did not then use some of the 22 AWG solid core insulated wire. Attach the magnet of the speaker to the (front side of the) perf board using double-stick foam tape.
