STEM skills for kids include knowing about fundamental engineering concepts.  Check out our articles on how electronics components work.  Read about important principles and how to apply them.

How do I know what level of resistance my resistor has?

How do I know what level resistance my resistor has? Through hole resistors like the ones in your projects have a series of bands on them that indicate how much resistance they provide. A resistor chart like the one below helps to decode the bands: For example, let’s...

How does a resistor work?

How does a resistor work? Many of your MakeCrate projects call for resistors of various strengths in the circuits, so you may be wondering what a resistor does, how they work, and what happens if you leave them out. Our article “How does an LED Work?”  introduced the...

How does an LED work?

Light-emitting diodes – commonly called LEDs– are found in several your MakeCrate projects. They come in a range of colors, sizes, and intensities. Our directions and videos emphasize that the LEDs must always be connected in the correct direction, and if you reverse...
