I was sitting in the armchair in the living room and I was maybe 13-14 years old. It was something that me and my dad was talking about that got me thinking.
I had heard somewhere that 1’s and 0’s was the foundation of computers, cell phones, TV’s, remote controls, digital watches… And I had accepted that.

A couple of years ago, I bought a robot vacuum cleaner.
It would run around our office and clean the floor.
It was not very efficient – but it was really cool!
Robots are just cool. And I have noticed that a lot of people want to build one. But how do you do that?
How can you make a device that measures the distance to the wall for example?
This can be done [Read more…] about How to measure distance?
As you know, when you are building something with electronics, you need a schematic to follow. It’s like your blueprint for making the circuit work.
You can either design this schematic diagram yourself, or you can find one that someone else has made.

…and I totally understand that. I was also very confused about it.
Does it mean you have to put a wire into the ground outside your house to make the circuit work?
Ground is confusing because it means different things in different situations.
But let me simplify it…
