Electronics explained in a simple way
I put together this Voltage Unit (VU) meter using LEDs on a breadboard the other day. It only has 4 LEDs, but can easily be expanded to more:
It’s basically a simple display for showing a value. It’s originally for showing signal level in audio circuits, but there’s no reason you can’t use it to show temperature, rain intensity, light level, or whatever other value you are measuring.

Do you want to give the gift of learning this year?
Below you can gift a one-year membership for Ohmify, including a starter’s component kit, to a loved one.
Ohmify consists of more than 20 electronics courses, with access to a community forum to get help with any topic or project.
It is made for people with little or no electronics understanding who want to be able to confidently create electronic gadgets and tools – and who are prepared to take action to make it happen.

The circuit uses standard basic electronic components and you can build it even if you have never built anything before. Check out the full build instructions in the video below:
Scroll down to find the complete circuit diagram, component list, and step-by-step instructions (in text-form) on how to build this circuit.

A breadboard is a really simple way to put together a circuit. You don’t have to solder, just plug in the components.
I love to use breadboards for testing out new circuits quickly.
You can build really cool things on the breadboard. For example, check out this color-changing lamp or this radar that detects my breath.
If you don’t know how to use a breadboard, don’t worry. It’s very easy.
Just check out my video:
I went to Berlin with Elias Bakken. It’s such a cool city.
We met up with Helen Leigh and Drew Fustini to eat kebabs, see homemade instruments, play artsy video games and learn about sewable circuits:
The RC delay element is a way to create a time delay in your circuit by connecting a resistor and a capacitor. It’s super simple. And very useful.
The ‘R’ is a resistor, and the ‘C’ is a capacitor. That’s where the ‘RC’ comes from. And here’s how you connect the two:
