If you want to get some sound out of your project but have a tight space budget, this is a good way to do it. This 2.5W, 4 Ohm speaker is only 28mm...

These ultra-fine wired LEDs are designed for model-makers and crafters but they could also come in handy for folks who want to add tiny points of l...

Push once to turn on, push again to turn off, push again to turn the other side on, one last push and it's off again! It's basically a push-button ...

Little clicky switches are standard input "buttons" on electronic projects. These work best in a PCB but can be used on a solderless breadboard ...

Schottky diodes are known for their low forward voltage drop and a very fast switching action. This 1A 40V Schottky diode is ideal for use with ...

For storing small parts (especially SMT/SMD components), these little modular boxes are ideal. They have individual clear pop-open covers so you ca...

This is a small 15mm round speaker that operates around the audible 2kHz range. You can use these speakers to create simple music or user interface...

If you want to do more with the BBC micro:bit, getting those pins from the card-edge connector is going to be your first hurdle. Unlike many dev-bo...
