This unit provides a simple way of adding flashing white LEDs to a textiles project using conductive thread. The unit is programmed with a number of flashing patterns, which are selected by a push button on the main board. Pressing this button cycles through the following patterns all LEDs constantly on, slow flash all on all off, fast flash each in turn and turned off. The device features auto-off, which turns the unit off after 30 minutes to preserve battery life.This kit is supplied pre-built so requires no soldering. Each kit comprises three small PCBs. The largest of the three PCBs holds an LED plus the control electronics, battery and a push button. On both of the remaining PCBs there is an LED, these are connected to the main board with conductive thread supplied.Depending upon flash pattern the battery lasts for approximately two days of constant use.Features Everything you need to complete one project.
