CD4017 Ring Gradient Led Water Lamp Diy Electronic Kit Fun Welding Production Parts for Traning and

1. Usually, only one LED light is turned on at a time. This circuit is to add a capacitor to the circuit of the LED water light to delay the time, so that the LED can achieve the effect of fading out.2. Equipped with blue and white adjustable potentiometer to adjust the water flow speed3. Good effect, with 20 bright LED lights4. The LED light will change from bright to dark, so it presents a gradual flowing water effect.5. The electronic production kit of circular gradient LED water lamp can increase the fun of DIYProduction skills:Soldering and component installation are the key to success. Please use high-quality solder. The solder joints should be bright and free of solder leaks. The components should not be installed incorrectly. Follow a certain order during production. After installing some components, install the other part. Start with short components, such as resistors, and to taller components. The integrated circuit is first installed with the tube socket, and then the chip is installed after all the installations are completed. The of the chip is facing the mark with the on the circuit board.After installation, check again whether the components are installed correctly, whether the welding is good, and then connect the power supply, pay attention not to reverse the positive and negative, turn on the switch, observe the LED flashing effect, and then adjust the potentiometer to observe the LED flow speed.Colour:As ShownMaterial:plasticPackage Contents:1 x DIY electronics kitOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
