If you are a student or educator of electronics, element14 is currently running a competition that's built for you.

If you know something about capacitors, how they work, and how to build basic circuits, this competition will increase your knowledge and give you a chance to win a NEW Digital Oscilloscope by Keysight.

We call this our "Experimenting with Polymer Capacitors" competition. Polymer capacitors are a special type of capacitor that uses solid electrolyte of a conductive polymer. It has special properties that make it great for all kinds of circuits.

All you need to do is experiment with the capacitors and tell us about your experiments in a 2 blogs. The best experiments will win a new oscilloscope!

We are giving away 5 capacitor kits along with a cap tester: https://www.element14.com/community/docs/DOC-92091/l/experimenting-with-polymer-capacitors-about-the-competition?ICID=ex…

The grand prize is

A Capacitive Touch Tutorial

Prepare to drink from the firehose! James opens this video with:

"Push buttons do not work without pull-up or pull-down resistors."

But what if you what a button without a physical button?

If you need a brush-up on Pull-up resistors,

check out this AddOhms Tutorial (also done by James).

In this video you'll learn about capacitors.

Capacitors are, at their most basic, two conductive electrode plates separated by a non-conductive dielectric.

An electric field forms between the plates. Different dielectric materials change how much charge can be stored in that field.

A dielectric (or dielectric material) is an electrical insulator that can be polarized by an applied electric field.

In this video you'll learn about:

the variables to consider in defining capacitance
the equation for defining capacitance
how to measure capacitance in a circuit
and what is different about capacitance when designing with capacitive touch.

James rounds out the video with a review of the TI CapTIvate Dev KitTI CapTIvate Dev Kit - which TI sent him to review.

Learn. Build. Share.

This kit has been created in partnership with Hackster.io. It includes parts that will allow you to build several fun projects and help you follow along with Hackster's learning tracks. Start learning how to build today and share your ideas and projects here on the element14 Community.

What can I build with this kit?

Make LEDs blink (the “hello world” of hardware projects)

Control a hobby motor

Compare sensor values from two very different light sensors

Experiment with switches and push buttons

Learn how a digital clock works using a seven segment display

Build basic prototypes with the breadboard and jumper wires
