How to make a video game controller with a sweet potato and a Makey Makey electronic board
Welcome back for a new Tech STEM tutorial specially made for your kids.
I think that if you are on this blog it's because you or your kids like to tinker, make things, learn how to code, learn how to make video game, like electronics and the list is still going on.
If that's the case, I think you'll be happy just by reading these few lines I'm typing right now.
Let's talk electronics
When we say electronics, that sounds so vague that sometimes we forget to decompose things in simple pieces. yes I know, even electronics can be understood. Lol
Electronics to work usually need a battery. It's everywhere in your product, from toys to your smartphones or tablets. It allows to have energy to the main active components you are trying to turn on. But let's talk about it in a couple of lines.
You also have a main other component called a switch. You usually use them to turn on or off the device you are using. Let's take a simple example such as a light bulb. Click Click, it's on or off. that's it.
And to finish this part, you may also need an active part, that may be a buzzer to make sounds, a diode to make light, a motor to move things or an electronic chip that does special things depending of it's manufacturer.

Electricity and conductivity
All the components we saw before needs to be connected together to work. This is what we call a schematic. It starts from the battery to bring the energy to our led or motor. To connect them together, you may need cables like the following schematic.
Cables have a good conductivity depending of their materiel. But what you need to remember is conductivity. Even you, you are conductive because you are made of 70% of water. Meaning the electricity can cross your body. that's why your family ask you since a young age to not touch electric devices, switches when your hands are wet.
Talking video games, these are popular since the 70's on the small screen. It usually started with a character that you control. This character may be a man, a car or a cat like the game we play in Scratch. Let's say the famous Pacman that patrol in a maze to it them all.
