A thermistor changes its resistance with temperature.
A thermistor is a type of variable resistor whose resistance changes with temperature. Let's take a closer look at the thermistor module.
3.3V : 'VCC' stands for Voltage Common Collector. We'll connect the VCC pin to 3.3V on the micro:bit
GND: In electronics, we define a point in a circuit to be a kind of zero volts or 0V reference point, on which to base all other voltage measurements. This point is called ground or GND.
DO: Digital Output
AO: Analog Output
Voltage is the difference in potential between two points. As it is difficult to talk about voltage without a reference point, we need another point to compare it to.
Jargon buster
Plain-language definitions for the technical terms used above.
- GND
- GND is the ground or reference connection (0 V) for a circuit. When connecting two devices together, their grounds must be joined so both agree on what counts as a low or high signal.
- VCC
- VCC is the positive power-supply connection on a chip or module. Connecting it to the correct supply voltage is needed for the part to power on and helps avoid damaging the electronics.
