Description:
The flash Christmas tree circuit is mainly composed of a multi-vibrator circuit formed by three triodes. D19 is a seven-color light-emitting diode, which can emit seven colors of light after being powered on. This kit has high success rate and strong interest, and is suitable for electronic enthusiasts to install and learn.
This kit consists of a 3-speed circuit board. During installation, the main LED and triode are inserted in the direction. The color of the LED can be combined by itself. After the insertion, the tube is left about 6mm and bent parallel to the circuit board. During welding, grasp the welding time, and do not damage the LED due to the long welding time. Note that the D19 on the JC162 board should be welded. After the JC161 JC162 components are welded, they should be inserted crosswise correctly, and then inserted on the base plate. When inserting, note that the power polarity marked on the JC161 and JC162 boards should be consistent with that on the base plate, and they should be welded and fixed after being correct.
After the installation is completed, the power can be turned on to test the effect. The power supply mode of this circuit can be selected from two ways, that is, three five dry batteries can be used for power supply, and if the battery is not used, the mobile phone charger (5V) can be connected through USB special cable to power the circuit.
Package Included:
1* Three-dimensional color Christmas tree LED water lamp kit
Circuit diagram:
It can be seen from the schematic diagram that 18 LEDs are divided into three groups. When the power is turned on, the three triodes will be on first. However, due to differences in components, only one triode will be o
