AVT 5695 LED Icicle Falling Light Effect Kits User manual

Brand: AVT

Model: 5695 LED Icicle Falling Light Effect Kits

Type: User manual

This circuit produces seven, fully user-configurable

lighting effects. These include effects reminiscent of a

falling light effect or a falling meteorite, an effect

known from the Knight Rider film, or a randomly lit

spot. You can adjust both the speed of each effect

and the length of its streak. Such light sequences can

be a wonderful addition to an advertising or even

festive lighting composition.

Features

• seven lighting effects

• 3-button control

• speed and streak control

• 12 outputs with 1 A (3 A) load capacity

• power supply: 12 V

• PCB size: 140×45 mm

Schematic diagram of the circuit is shown in Figure 1.

Its operation is controlled by a ATTINY2313

microcontroller clocked by an internal clock signal.

This circuit must be supplied with 12 VDC lead to the

IN connector. The IRF9530-type transistors were used

as actuators.

Twelve transistors and LEDs, are controlled directly

from the microcontroller ports. The use of a

microcontroller in the role of LED driver definitely

simplifies the circuit and offers unlimited possibilities

in terms of achieving any imaginable lighting effects.

The circuit is powered by a safe voltage of 12 V, and

its output can be connected directly to 12 V LED

bulbs or strips.

Mount the circuit on a printed circuit board, its

component layout is shown in Figure 2.

Perform mounting according to general principles,

starting with the soldering of the lowest components

- the resistors - and ending with the highest

components - the buttons and the screw connection.

Three buttons S1-S3 are used to operate the device.

Pressing the S1 button will change the effect; the LED

corresponding to the effect number as stored in the

microcontroller

is lit for a moment. The S3 button is used to change

the effect speed, while the S2 button changes the

length of its

trail.
