Do you want to build a circuit that blinks a light? This inverter-based circuit is simple, and it’s small enough to fit on a breadboard.

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:

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.

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:

Thomas was right. It was impossible to get anyone to do anything in December in Medellin. So I continued on my own.

There was one challenge left before I could assemble it all and program the robot: The ultrasonic sensor.

I hadn’t tested it yet, so I had no idea how well it would work.

This week we got a new member. So we revised what we’ve done so far with our new member:

The first week we looked at different robot platforms. We wanted to be able to go forward, backward, and make turns. And we wanted it as cheap as possible. We looked at different platforms at the local store, then settled for one with three wheels, three levels and two motors.
