Capacitive touch dimmer Constant pressure stepless PWM control Arduino

Features: TI LED lighting control touch input corresponding to the output. There are four functions optional by the T1 and T2 input pin before power State to decide. Details as follows: 1. T1 = 1, T2 = 1 corresponds to: LED touch without sudden brightness memory sudden bright dark stepless dimming function 2. T1 = 0, T2 = 1 corresponds to: LED touch without brightness memory slowly fades stepless dimming function 3. T1 = 1, T2 = 0 corresponds to: LED touch with brightness memory slowly fades stepless dimming function 4. T1 = 0, T2 = 0 corresponds to: LED three sections touch dimmer function LED touch stepless dimming brightness memory without sudden bright sudden dark as follows: On initial power-up, shut off the lights for the state. Liang tapping the touch (touch duration is less than 550ms), it can achieve control lights off. One-click touch, lights; again tap the touch, light off. So the cycle. Light is on or shut off when no brightness buffer. The initial brightness and illumination lighting is fixed at 50% of full brightness. Long press the touch (touch for longer than 550ms), it can achieve stepless dimming light. A long press touch, light intensity and gradually increase light levels when released after the release time parked in the corresponding brightness, if long time more than three seconds, the light intensity does not change the maximum brightness; press the touch again, light intensity decreases, stop light levels when released in the release time corresponding brightness, if long time more than three seconds, the light intensity has reached the minimum brightness does not change. So the cycle.
