LED STAR

Many times we have needed decorations for our homes, the most common at Christmas time, but this time we have developed a project that is very easy to do, which is a led star with an intermittent led light that gives us an innovative decoration for our rooms or other spaces.

Many times we have needed decorations for our homes, the most common at Christmas time, but this time we have developed a project that is very easy to do, which is a led star with an intermittent led light that gives us an innovative decoration for our rooms or other spaces.

The operation of this project is based on the transistor oscillator, this oscillation comprises two factors: the resistance and the capacitor, when capacitor 1 is discharged the other capacitor is charged and makes Q1 work, but when the capacitor of Q1 is discharge the capacitor of Q2 makes the transistor Q2 work and thus we can visualize the intermittence of the leds. This is a basic but very functional project since we can handle many leds at the output. For this case we use only 12 leds for each transistor output.

For this project we have used the following electronic components:

§ 1 DC JACK

§ 2 TRANSISTORS NPN 2N2222A

§ 2 RESISTORS OF 1/4W 22K

§ 2 ELECTROLYTIC CAPACITORS 100UF 16V

§ 6 RESISTORS 1/2W 220 OHM

§ 12 LEDS 5MM RED COLOR

§ 12 LEDS 5MM GREEN COLOR

§ 1PCB

Project features:

§ VIN 9V – 12V

§ LEDS intensity 20mA

§ Oscillation frequency 1hz – 100hz
