Here is the transistor graphic equalizer circuit. Why should make this circuit? We use it for controlling the audio frequency in some kinds of audio frequency responses that are not flat. Which we cannot use a normal tone control circuit. Because it has a too wide bandwidth. We need to use a good equalizer circuit … Read more
IC 4017 CMOS-Decade counter/divider. When we build the 10 LEDs running light for hobby. Often use IC-4017. This really neat chip contains counter,decoder[…] Read more
We use voltage dividers regularly in electronics, sometimes without even knowing it. But how do voltage dividers work? In this article, we will learn about the voltage divider rule, how to calculate the resistance value, and how to use it in actual circuits. A voltage divider is a very basic part of electronic circuit building. … Read more
