Jumper Settings:

1. T1 = 1, T2 = 1 corresponding: LED touch step-less dimming without brightness memory
2. T1 = 0, T2 = 1 corresponding: LED touch step-less dimming function without brightness Memory fading
3. T1 = 1, T2 = 0 corresponding: LED touch step-less dimming function with brightness Memory fading
4. T1 = 0, T2 = 0 corresponding: led three touch dimming function

Touch Functions:

A) when the touch is clicked (the touch duration is less than 550ms), the light on/off control can be realized. Once click touch, the light is on; once click touch, the light is off. This cycle. When the light is on or off, there is no brightness buffer. And the initial brightness of the light is fixed at 50% of the full brightness.
B) Press and hold the touch for more than 550ms to gradually increase the brightness of the light. When released, it stops at the brightness corresponding to the release time. If the press for a long time is more than 3 seconds, the brightness of the light will not change after reaching the maximum brightness.
C) Click the touch to turn on and off the light, the light smoothly reduces from the current brightness until it is turned off It can achieve the visual buffering effect of slowly changing brightness and protect the eyes and vision.
D) Under continuous power supply, the brightness will be memorized each time turn off the light, and the next time you click the touch to turn on the light, the brightness will be used as the initial brightness. In case of power failure, the first time after power on, click touch to turn on the light, and the initial brightness is fixed at 50% of the full brightness.
E) LED three touch dimming function: Click the touch, the light brightness is in the order of low brightness → medium brightness → high brightness → off

Debugging tips:

If it is triggered by mistake or not during debugging, it

Specification:

• Installation: without direct contact with copper foil, dimming can be carried out by more than 3mm acrylic glass or plastic.
• Voltage range:2.4-5V; Maximum output current:500MA; Hole distance:16MM; Aperture:2.5MM
• Function: single line touch, using the principle of capacitive touch, sensitive touch. By default, it has switch function, dimming function and stepless dimming function of LED touch with brightness memory. Turn on the light slowly, turn off the light slowly dark, effectively avoid eye irritation.
• Wiring mode: in PCB board (VCC, GND) is power input, (LED +, led -) is led lamp positive and negative (fingerprint) is touch area, and it can also be wired out (note that the wiring should not be too long, after the outgoing line, it is recommended to use a small copper sheet as the sensing area), and the copper sheet area is recommended to be 2x3cm left and right. The copper foil module on the board pastes one side of the copper foil on the shell side.
• Dimming mode: stepless PWM dimming; Initial powered on, the lamp is off.

    Capacitive type touch jog switch module The module is based on a touch detection IC (TTP224). Under normal conditions, the module output low, low-power mode to mode; a touch of a finger when the corresponding position, the module will output high, the mode is switched to fast mode; when for 12 seconds without touching, the mode and switch to low power mode. The module can be installed in such as plastic, glass surface non-metallic materials, in addition to the thin paper (non-metallic) covering the surface of the module, as long as the correct location of the touch, you can make hidden in the walls, and other parts of the desktop button. This module allows you to remove the troubles of conventional push-type buttons.

• Onboard TTP224 capacitive 4 key touch induction IC.
• Onboard the 4-way level indicator.
• Operating voltage:2.4V-5.5V
• The module can set the output mode, output the longest time, and fast/low power selection.
• PCB board size:35(mm) × 29(mm) x 7.2 (mm).

• (1- > Short ; 0- > No Short)
• AB=00: No-lock High TTL level output;
• AB=01: Self-lock High TTL level output;
• AB=10: No-lock Low TTL level output;
• AB=11: Self-lock Low TTL level output;

Specification:

• IC: TTP224 4 Channel; Jog type: the initial state is low, high touch, do not touch is low (a similar touch of a button feature) Low power consumption
• Power supply: 2 ~ 5.5V DC; Positioning holes: 4 M2 screws positioning hole diameter is 2.2mm, the positioning of the module is easy to install, to achieve inter-module combination;
• Touch surface can be used as positive and negative, can replace the traditional touch of a button
• Control Interface: A total of three pins (GND, VCC, SIG), GND to ground, VCC is the power supply, SIG digital signal output pin;
• Touch area: Similar to a fingerprint icon inside the area, you can touch the trigger finger.
