What is Chaser Light System?
An LED chaser or sequencer is a popular LED driving circuit. It's used in running-light rope displays to flash different lighting patterns. In a chaser or sequencer circuit, a controller commands the sequence and timing of the flashing LEDs to illuminate different kinds of lighting patterns.
How to Works Chaser LED System?
This is the circuit of a simple LED chaser.
1. The Light Bulb Circuit Diagram
The LEDs light one by one for a period of 1second and the cycle repeats giving the running light appearance. The circuit uses two ICs (one is 555) to drive the LEDs. IC1 (NE555) is the popular timer IC wired in the Astable Multivibrator mode.
1.IC NE555 : 1x
2.IC CD4017 : 1x
3.LED : 11x
4.10uf Capacitor : 2x
5.9V Battery : 1x
6.10k ohm resistor : 2x
7.680 ohms resistor : 2x.
2. Voltmeters and Ammeters
Before coming to the lab and working with some real circuits, here’s a chance to spend some time with simulated circuits. This will teach you how to use voltmeters and ammeters in a circuit, which is a crucial skill this semester. Further, this Pre-Lab will give you a very brief introduction to Kirchhoff’s Rules, which will form the backbone of any circuit analysis course you take in the future.
3. Light Bulbs in Series
If you know a few simple things, using the power supply is straightforward. There are two knobs. The top knob adjusts the voltage of the supply. This is the knob that you will turn as you are doing the experiment. The bottom knob is a current limiter. You don’t need to adjust this knob during lab. Just make sure that it is turned all the way up (clockwise) and leave it there.
