Voltage Sensors,e 5V supply inside the NXT or some part of it divided through an external resistor. It probably doesn’t come as a big surprise that you can connect an external voltage to the input and have the NXT convert that instead.

4.3V Powered Sensors, of sensors powered this way.) It’s defined as the 4.3V power supply, but the voltage actually varies about 7% with load. The plot in Figure 8-1 shows the voltage ranging from 4.6V, when the power supply is lightly loaded, to 4.0V when it’s fully loaded. It is important to note that this plot is for the total current of all the ports put together.

Susanne Mingers,Philipp Wildburgtact sensors use the same NXT-G Touch Sensor block shown in Figure 4-1 as the LEGO ones. You probably already have everything you need to homebrew one. Even if you don’t, the parts are readily available from electronic stores such as Radio Shack, and even from hardware stores.

You probably figured out that passive sensors were the type that didn’t. The contact sensors you learned about in Chapter 4 were also passive sensors.

Rotating the shaft changes the resistance between the center and outer two terminals. It’s a kind of self-contained voltage divider. Usually t
