NE555 + CD4017 Water Flowing Light LED Module DIY Kit comes with all the components you need to assemble and solder a running LED module. It has a double-sided board with surface mount and through-hole configuration. It is designed for users with advanced soldering skills. You must solder some components on the top surface and some components on the bottom side of the board. The module has a very simple assembly process will take anywhere between 30 minutes to an hour.

NE555 + CD4017 Water Flowing Light LED Module DIY Kit

This Kit is mainly decimal counter circuit and circuit generated by the clock, from the core of the self-excited NE555 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 oscillation 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 at a high level, the D1 – D10 are sequentially lit to form a water-light effect. You can adjust the flow rate adjustment R4 LED light.



Note: All component will be sent unassembled, you need to assemble and solder it by yourself.

  2. Anil Raghava Kurup (verified owner)

    Best kit to start on your SMD board development. The board is simple to complete, except that you need to align the SMD components properly and aesthetically.
