Single touch LED light bar control MCU

• Single touch LED light bar control MCU
  This MCU is an LED touch dimming control board scheme with touch switch dimming, touch key control and debugging LED light size, and stepless dimming function. The sensing mode of this circuit is touch switch or dimming. This MCU is mostly used for LED vanity mirror, led eye protection table lamp and other LED lamps.
  Single touch LED light bar control MCU function description:
  1. The input voltage is DC5V to charge the 3.7V lithium battery. The charging current can be preset to 300mA ~ 1500mA. It doesn‘t work when the power is turned on. The standby current is less than 10 μ a.
  2. Two LEDs, one is cold white and the other is warm white. Short press to cycle to change the LED working mode. Initially, turn on the cold white light with an initial brightness of 100%. Short press warm white, light it at the same time (cold white plus warm white), and short press to turn off standby. Long press the first brightness reduction, long press the second brightness increase, and cycle. Touch and hold the stepless dimming time for 3 ~ 4 seconds.
  3. This MCU software can be preset as: A. no brightness memory, no delayed shutdown, B. brightness memory, no delayed shutdown, C. no brightness memory, delayed shutdown, one of three.
