Rotary encoders can be used similarly to potentiometers. The difference being that an encoder has full rotation without limits (It just goes round and round). This is a quadrature encoder and outputs similar to 2-bit gray code so that you can tell how much and in which direction the encoder has been turned. They're great for navigating menu screens and things like that.
This encoder is especially cool because it has a common anode RGB LED built in, as well as a push-button. Look below for the clear knob that goes with this potentiometer.
Klassischer MiFare Tag. Kann für beliebige Projekte im Bereich elektronische Schlößer, Identifizierung oder überall wo kleine und leichte Tags benötigt werden, genutzt werden. Der Tag hat einen NXP S50 Chip und eine Antenne und wird passiv geladen, wenn er nahe genug am Leser/Schreiber ist.
This is a blank MiFare Classic \'laundry\' tag - often used for laundry or identification but also found in other systems where a small proximity card is desired. This one is clear! The tag contains a NXP S50 chip and an antenna, and is passively powered by the reader/writer when placed a couple inches away.
This adapter allows you to connect a barrel jack connector to bare wires. One end has screw terminals and the other has a 5.5x2.1mm, center-positive female barrel jack. If you have a power supply with a barrel jack and want to plug it into a breadboard, this might be the simple solution.

This sensor uses an infrared emitted diode combined with an infrared phototransistor to detect the reflected infrared signal. Ideal for sensing black-to-white transitions or can be used to detect nearby objects (.5-1cm).
The Hall Sensor measures the Hall Effect, which is a production of a voltage difference across an electrical conductor, transverse to an electric current in the conductor as well as a magnetic field perpendicular to the current. The output of the Hall sensor switches low and turns on when a magnetic field perpendicular to the Hall sensor exceeds the BOP...
