Did you know that every time you press a key on your keyboard, you're sending something very similar to Morse code? In Morse, you have dots and dashes. In digital electronics, you have ones and zeroes. When you press the 'A' key on your keyboard, the code 00011110 is sent. If there is voltage on the wire, it's a one. If there is not, it's a zero. When my dad taught me this as a kid, I was in awe. It was so simple! I started reading about things like logic gates that let you do stuff with the ones and zeroes - also called the "bits". Logic gates are digital building blocks that let you add logic into your circuits. Such as the AND gate: You can use these gates to add logic to your circuit, such as "if these three buttons are pushed at the same time, activate the electromagnet". The electromagnet can be used to unlock a door, and thereby you've created a super simple code lock! Logic gates are the building blocks of digital electronics, which is what all modern gadgets are made of. If you haven't learned the basics of digital electronics yet, I highly recommend it. It will open up a whole new and exciting world for you. Digital electronics is just one of the things you can learn at Ohmify. And you have a group of friendly people that you can ask questions if you get stuck or are struggling to understand something. Click here to learn more about becoming a member >> |
