Kit name: stereo color christmas tree operating voltage: DC4.5-5V
The flashing christmas tree circuit consists of 3 three-pole tube multi-harmonic oscillator circuit, D19 is a colorful led, which can emit seven colors of light after electricity.This production success rate is high, interesting, suitable for electronic enthusiasts installlation and learning.
This kit has 3 circuit boards, when installling, notice the direction of LED and three-pole tube plug-in, the color of LED can be self-assembled, after plug-in tube foot leaves about 6 mm and bends parallel to circuit board, welding time, do not cause LED damage due to excessive welding time.Note the D19 final welding on board JC162, JC161, JC162 welded components, correct cross-insert, then insert on the floor, insert attention to the JC161, JC162 plate and the power indicated on the floor to the polarity of the same, correct welding fixed.
After the installlation, the test results can be checked correctly, the circuit is powered by 2 options, both by cell 3-5 and by cell charger (5V) via USB special line (optional).
