    Simple breakout board for the 3.5mm audio jack. Use this breakout (shipped bare) to allow breadboard or SIP access to the super-common 3.5mm audio jack. All five pins are broken out.

  7. Exc. VAT: £0.58 Inc. VAT: £0.70
    This is a 3.5mm TRRS SMD audio jack. TRRS connectors are the audio-style connectors that you see on some phones, MP3 players and development boards. TRRS stands for "tip, ring, ring, sleeve," which reflects the fact that, unlike a standard stereo connector, this actually has three conductors and a ground. Some devices use the extra conductor for a microphone (like hands-free headsets) or to carry a video signal (like in some MP3/MP4 players).

  8. Exc. VAT: £0.58 Inc. VAT: £0.70
    This is the kind of 1/4" stereo jack you might find in home stereos and PA systems. Switched contacts allow you to detect whether or not there is something plugged in to the jack. The jack can be panel mounted in an 11mm diameter hole.

  9. Mini Photocell Sale
    Exc. VAT: £0.65 Inc. VAT: £0.78 £1.00

    This is a very small light sensor. A photocell changes (also called a photodetector, photo resistor, CdS or photoconductive cell) resistance depending on the amount of light it is exposed to. These little sensors make great ambient light triggers (when light in the room turns on, do something).

    The US1881 is an integrated Hall-Effect latched sensor. That's nice but what does it do? Holding a magnet near the sensor will cause the output pin to toggle. This makes for a robust presence sensor. A reed sensor also works nicely, but can be limited by the glass encapsulation and size. A Hall-Effect sensor is much smaller, but can handle less current than a reed switch.
