Product details

Christmas tree led flashing lights small DIY puzzle
Colour:green
Material:metal
The circuit is composed of 16 LED (light-emitting diode). The 16 LED is divided into four groups, and each group has a different flashing frequency, when the four groups of LED lights together after the flash, like a bright Christmas tree, and this circuit from the 9V battery.
The advantages of this circuit: simple and practical, low power consumption, and the circuit is the use of integrated circuit drive, fewer parts, easy to understand the line, the package of external connections, all with plug plug, easy to replace parts at any time And conducive to circuit debugging. But also let us in the debugging process to deepen the understanding of the principle of the circuit.
This line is generated by the cycle of the oscillation circuit, the principle is as follows:
1, after the first charge, the capacitor C1 & C4 charge is completed.
2, the capacitor C2 & C3 will continue to charge.
3, when the transistor Q1 & Q4 conduction at the same time, the capacitor C1 & C4 will discharge.
4, capacitor C2 & C3 is fully charged, the transistor Q1 & Q4 will be closed, and capacitors C1 & C4 again charge.
5, transistor Q2 & Q3 conduction at the same time capacitor C2 & C3 will discharge.
And so on, the flash speed is the oscillation frequency, and the frequency value by the resistance R & capacitor C value of the decision.
Package Contents:1 X Christmas tree led flashing lights
