Inertial Measurement Units (IMUs)

Inertial Measurement Units (IMUs) are devices that combine accelerometers, gyroscopes and sometimes magnetometers together as a single device. These days they are usually made with MEMS technology and are housed in tiny SMD packages.

Light-Dependent Resistors (LDRs)

LDRs are simple electrical components whose resistance changes with light intensity. They are useful as a cheap solution for basic light detection.

Magnetic Rotary Position Sensors

Magnetic rotary position sensors (a.k.a. encoders) use magnetism to measure the angle of a sensor. This page covers Hall-effect and GMR sensors.

Phototransistors

Phototransistors are transistors which can be used to detect light. They are similar to photodiodes, but are more sensitive (i.e. have a higher output current for a given amount of light) at the expense of a slower response time. This page covers how they work, schematic symbols, important parameters, circuits, applications, suppliers,and more.
