I was first introduced to logic gates when I was around 14 years old. I had heard that computers consisted of ones and zeroes. But I didn’t understand what that really meant. So I asked my father to explain it. And I loved his explanation because it was so simple and easy to understand. Read […]
What is a 1 and a 0? How can you build circuits with them? And why are these numbers the basics of all modern electronics?
Digital electronics is what enables all the advanced gadgets you see around you today, like mobile phones, computers, and TVs.
It seems so complex, but when you break it down to its smallest parts, it’s actually quite easy to understand what is going on.

New Resource: The CMOS 4000 series of ICs
Do you want to build simple digital circuits with 7-segment displays, counters, adders, and other logic circuits? Then you need to check out the 4000 series of CMOS chips. I am working on writing articles for these chips and I am at 9 artices so far. If there is a chip you’d like to learn […]
How To Choose A Pull-up Resistor Value
I recently got a question about choosing a pull-up resistor value: Hey!In Monostable button triggered circuit, why did you connect 10 kΩ specifically? Does it contain any calculations? You can use resistors for many things. In the following 555 timer circuit that he was referring to, the resistor R2 is a pull-up resistor with a […]
Binary Number System And Working With Ones And Zeroes
The binary number system is an important system in digital electronics. Because in digital electronics we are using only 1’s and 0’s. But what does this mean? That’s something I was wondering about for a long time. I thought it was something really difficult and abstract. But when I one day asked my dad about […]
