Amplifying Signals Breadboarding: from a diagram to an actual working amplifier. Breadboard connections? Each block of 5 sockets or “holes” have The power common wires rails are underneath connected all the way across the row Breadboard connections: These are now connected These are now connected How about these sets of wires? NOT ? NOT ? These are connected Common wires underneath means… Yes ? This is a diagram of an amplifier circuit. We could just connect these wires, but using a breadboard is easier… +9 V Power supply audio input Variable Resistor GROUND 8 7 6 5 1 2 3 4 output to speaker - Terminal + Terminal Power –9 V supply
