Building the MOSFET circuit

We will build our circuit in two parts, starting with the placement of the components on our breadboard:

Figure 7.9 – MOSFET transistor circuit (part 1 of 2)

Following are the steps for the first part of our build. The step numbers match the numbered black circles in Figure 7.9:

1. Place the MOSFET into your breadboard, taking care to orientate the component the correct way around regarding the Source, Gate, and Drain legs. Our example layout assumes a 2N7000 MOSFET. Please see Figure 7.8 if you need help to identify the legs.
2. Place a 100kΩ resistor into your breadboard. One end of this resistor connects to the Gate leg of the MOSFET.
3. Place a 1kΩ resistor into the breadboard. One end of this resistor also connects to the Gate leg of the MOSFET.

4. Place the LED into the breadboard, taking care to orientate the component as shown regarding its cathode leg.
5. Place a 1kΩ resistor into the breadboard. One...
