It is time to learn the Essentials with Karen and Ben this week, Karen has a project that requires a bit of intelligence and discrete electronics can provide just that. To make the laser cut Star Wars BB8 art light reactive, Ben helps to explain and design a circuit using active and passive components, from resistors, capacitors and inductors to diodes and transistors. These components make the basis of smart electronics we experience today, from video cameras to smart phones. Watch now to find out how you can make your project light reactive with a photoresistor and discrete logic! Let us know what art work you have been creating, or how you would want add that bit more control on the element14 Community.
