LED Chaser using IC 74C164: 8 LEDs turn ON one by one, Shut off, then Repeat
Referring to the following chaser circuit diagram below, we can see a low-frequency, astable oscillator circuit, made up of two gates, IC1a and IC1b, from the IC 4011 quad two-input NAND gate. The operating frequency of this astable is determined by the values of C1 and R11. This circuit configuration works well as a clock-pulse […]
LED Chaser Circuit using IC 74LS164: LEDs illuminate in Bar Mode then Shut off together or one by one
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 […]
Capacitor Based LED Tubelight Using 1 Watt LEDs
In this post I have explained the construction of a homemade 100 watt capacitive tubelight circuit using 1 watt LEDs. The idea was requested, constructed, tested and verified by one the avid readers of this blog Mr. Tamam. Let’s go through the entire discussion. Discussing the Proposed The Design I regularly visit your blog, and […]
How To Calculate and Connect LEDs in Series and Parallel
In this article I have explained how to calculate LEDs in series and parallel using a simple formula and configure your own personalized LED displays, now you don’t just have to wonder how to wire led lights? but actually can do it, know the details here. These lights are known not only for their dazzling […]
How to Understand and Use white LEDs – Datasheet
If you are wondering how to correctly use white LEDs in circuits so that they can be illuminated safely without damaging, then this post might help you to evaluate the same. Introduction White LEDs are the future lighting solutions for our cities and homes. They will be easily replacing the traditional CFL and other flurescent […]
