General description This device is created to be a garland. It may be used in

commercial purposes and as a gift. The algorithm of work of this device is the following: when a

button is pressed the LEDs change their mode of operation to the next one. This happens by means of software. There are four different modes of operation. When power is supplied all letters get light up. When the button is pressed at first lights up the sign “ПО” then “41”. This mode will not change untill the button is pressed once more. When the button is pressed the next time at first lights up “П” then “O” (meanwhile “П” remains on) after that “4” and then “1”. All letters remain on until “1” lights up. At this point all signs turn off and this mode start over again. When the button is pressed once more the twinkling mode starts. In this case All signs go on at once and turn off at the same time as well. When the button is pressed for the next time the device goes back to the first mode when all signs remain on.
