Soldering Practice Board. LED chaser Kit with SMD and Through hole components

A great way to practice soldering. The DIY light chaser kit includes both SMD and through hole components. You get everything from resisters, capacitors, diodes, to LEDs and IC chips more. Factory Description – How does it work: This Kit is a decimal counter circuit generated by the clock from the 555 multivibrator power through R2, R3, R4 charge the capacitor C1, C1 started when charging , NE555 2 feet still in low, so the output pin 3 goes high when power through R2, R3, R4 to charge C1 to 2/3 of the supply voltage , the output pin 3 level from high to low , NE555 conducting internal discharge , capacitor C1 through R4, R3, NE555 7 feet discharge until the voltage across C1 is less than 1 /3 of the supply voltage , NE555 and 3 feet level from low to high . C1 and charge again this cycle oscillations formed . Charging time : 0.695 (R2 R3 R4) C1, discharge time : 0.695 (R4 R3) C1, R4 can be adjusted to control the output frequency of the oscillator , the oscillation clock signal is applied continuously NE555 CD4017 14 feet , the output terminal 10 is connected with the CD4017 10 LED, when the output terminal 10 turns CD4017 generated clock signal is applied at a high level , the D1 – D10 are sequentially lit to form a water -light effect .R4 adjusts LED flow rate. Board size. 53mm x 19mm Supply Voltage :2.5 – 14 .5 V
