KITS LED Fan Educational Soldering Kit Operating instructions

Brand: KITS

Model: LED Fan Educational Soldering Kit

Category: Soldering irons

Type: Operating instructions

KITS LED Fan Educational Soldering Kit lets you build a personal electric fan with 19 LED diodes that rotates with two selectable speeds and directions. You can use the buttons to switch the LED diodes with a phasing-out effect, creating a unique lighting display. This DIY kit is perfect for learning about electronics and soldering, and the assembled fan can be used as a fun and educational decoration.

• switching LED diodes with the phasing out effect

The effect of this module is achieved through a

system of 19 LED diodes grouped into 3 blade arms

and perfectly imitating the movement of a real fan.

Two operating buttons control direction and speed of

the LED animation and allow for hours of play and

creative use of the personally assembled circuit.

Specifications

• 19 LED diodes

• 2 buttons for controlling speed and direction

• power supply: 9VDC (6F22 battery not included)

• LED animation imitating a rotating electric fan

Begin by soldering the elements onto the circuit board in order from smallest to largest.

When assembling the elements marked with “!” pay attention to their polarity and placing of the notch.

You may find the frames with symbols of these elements on the circuit board, as well as photos of the assembled kit helpful.

seconds.

Too much tin solder can result in forming a ball

instead of a cone or joining of two adjacent

soldering points.

The whole process should take approx. 2-3

Next, apply tin solder

After the cone forms, remove tin solder first,

and then the soldering iron

Inadequate temperature, amount of tin solder or

impurities can lead to so called “cold solder

joints, i.e. solder and the flux can’t moisten the

two surfaces and the resulting solder point is

fragile and in time will oxidize, break, and stop

working.

The cleanness of the soldered surfaces, right

amount of flux in the solder, adequately high

temperature (320-360°C), and sufficient amount of

solder are necessary to complete a correct

bonding.

Thank you for purchasing AVT product. Please take your time to read carefully the important information below concering use of this

product.

• The product itself and all parts thereof (including packing material) are not suitable toys for childern! (choking hazard, risk of electric

shock, ...)

Failures in modern electronic component are very rare as 95% of non-working kits are due to poor soldering or components placed in

the wrong location or orientation so please check your work carefully.

• If the kit is used to switch currents greater than 24V it is necessary to have the installation and performed by a trained professional

authorized for such work. The kit may only be used in such application if it was installed in a safe to touch enclosure.

• If the kit is used in schools or educational facilities or similar institutions the operation must be supervised by trained and authorized

staff.

• Never exceed the limits or ratings listed in the 'Specifications' section at the this user guide.

• Battery or wall-adaptor are safe devices. They do not require special attention unless main voltage is connected to an output e.g. a

relay.
