Supreme 100 Led Christmas Lights Circuit Diagram

It is actually a schmitt trigger quad nand gate having two input terminals.

100 led christmas lights circuit diagram. Led christmas lights circuit description. The lights will get on at night and off in morning time. If your micro controller is 3 3v or less you need to use circuit 4 and set your micro controller s output pin to be open collector which allows the micro to pull down.

Led christmas lights wiring diagram. Here both the transistors switches alternatively thereby producing square waves which in turn activate the led s connected through it achieving a attractive pattern of alternate lighting effect. I am working with a 70 light string which consists of two parallel circuits that have 35 lights each in series.

This ic has a built in oscillator with a frequency set by the combination of resistor r1 and capacitor c1. It is based on a type 4060 digital counter ic1. Pin 1 can.

The above circuit uses two simple transistors which was wired in astable mode of operation. Connect to a micro controller pwm or a computer. The oscillator signal is divided by various factors by the internal digital circuitry of the ic.

All leds are employed in this circuit with a sensor along with some other components like transistor diode and resistors. The led christmas lights circuit has a very simple design. Led christmas lights circuit diagram and working.

This circuit is mainly made up of cd4093 ic. When one of the led s fails the circuit breaks which affect all the other lights half of them that are in the same series circuit. The micro controller s output pins are only rated for 5 5v usually that s why the zener diode is important.
