Building the RTTTL circuit

In this section, we will be building a circuit to drive a passive buzzer. This circuit, shown in Figure 8.8 is very similar to the MOSFET circuit that we covered in Chapter 7, Turning Things On and Off, only this time with a buzzer connected as the load:

Figure 8.8 – Buzzer driver circuit Schematic

We will start our circuit build by placing the components onto our breadboard:

Figure 8.9 – Buzzer driver circuit (part 1 of 2)

The following step numbers match the numbered black circles in Figure 8.9:

1. Place the MOSFET onto the breadboard, paying attention to the orientation of the component with regards to the legs. Please see Figure 7.7 in Chapter 7, Turning Things On and Off, if you need help to identify the MOSFET's legs.
2. Place the 100kΩ resistor (R2) into your breadboard. One end of this resistor shares the same row as the MOSFET's Gate (G) leg.
3. Place the 1kΩ resistor (R1) into your breadboard....
