The more moderen LED controllers for LED Christmas lights use alternating polarity to force two channels of LED lights. This implies it can be no longer viable to circumvent the controller internally to discontinue the lights flashing. While you have an understanding of why these controllers don't store their last atmosphere it is rather worrying. It's in simple terms the omission of a single affordable memory chip from the controller, which does have a space for it. On many units the reminiscence operate is in situation, so this is clearly an non-compulsory "price introduced function". Placing the chip in does require particularly destructive opening of the case and the soldering in of a tiny floor mount reminiscence chip. This makes it a challenge nice applicable to the electronically inclined. The chip required is a 24C02B although I used a 24C02N. It can be an extraordinarily usual low degree EEPROM memory chip.
