This circuit is actually a little more advanced LED chaser scanner circuit using two 74LS164 Shift Register ICs together with one NE555 Timer, and yep the light effect looks somewhat similar to those old Knight Rider or Mustang scanner lights which move from sides toward center. The LEDs are arranged in two strips, or sometimes […]
Newly Updated Circuit Projects:
Sound Activated LED Lamp Circuit
A highly sensitive sound activated LED lamp circuit can be built using just a few transistors and resistors. The circuit is actually a high gain MIC amplifier circuit which amplifies the external sound hitting the MIC. The amplified signal is then used to momentarily illuminate a bunch of LEDs. What does the Circuit do? Basically, […]
LED Light Wave Effect Generator Circuit
In this post I have explained a simple LED light wave effect generator circuit which will sequentially create a difference in brightness over a chain of LEDs, creating a chasing light wave kind of visual effect.
Automatic Night Activated Wireless Light Circuit for Paintings
In this article I have explained a basic wireless LED light circuit that may be used to autonomously turn on LED lights to illuminate artworks at nighttime.
8 Channel Lighting Sequence Generator Circuit for Christmas, Diwali Decoration
In this post I will explain how to make one full adjustable lighting sequence generator which can control and illuminate many external bulbs through triacs in many different running patterns. We can make it so that user can change and select any sequence pattern easily. We will use Arduino for the full control part. Let […]
Blinking LED Bow Tie Circuit
In this article I have explained how to build an LED bow tie circuit which will activate and blink a few LED lights stuck on your bow tie in response to your voice sound. It means, the LED lights on your bow tie will flash and blink, whenever you speak, creating a very eye catching […]
