Touch dimming table lamp electronic diy kit

The touch dimming table lamp electronic diy kit, easy to assemble, accessories are all precision-made, quality assurance, long life, stable performance. It has the function of touch dimming, and can realize the control of lighting on and off at the same time. There are three brightness levels of low brightness, medium brightness, and high brightness, and the brightness can be adjusted according to your own needs. It is easy to use and has strong practicability. Also suitable for electronic enthusiasts who practice soldering.

Kit parameters:
Battery capacity 450mah
Charging current: 1C about 450ma, one hour fast charge
Charging voltage: 5V
Interface: microUSB
PCB board model: WK-56-72

Note for novice welders: LED light panels dissipate heat quickly, so it is easier to tin them first and then solder them. Assemble the plastic-coated iron pipe in the middle and fix it at both ends with screws.

LED three-segment touch dimming function description:
1. When initially powered on, the light is off.
2. Every time you click and touch, the brightness of the light changes in a cycle of low brightness→medium brightness→high brightness→off. When the touch is clicked (the touch duration is less than 550ms), the light can be controlled on and off. Click and touch once and the light will be on; click and touch again and the light will be off. So cycle. There is no brightness buffering when the light is on or off. And the initial brightness of the light is fixed at 50% of the full brightness. When long pressing the touch (touch duration is greater than 550ms), the light brightness can be adjusted steplessly. Once you press and hold the touch, the brightness of the light will gradually increase. When you release it, the brightness of the light will stop at the corresponding brightness at the time of releasing it. If you press and hold for more than 3 seconds, the brightness of the light will not change after reaching the maximum brightness; press and hold the touch again, The brightness of the light gradually decreases, and when the button is released, the brightness of the light stops at the corresponding brightness at the moment of release. If the long press time exceeds 3 seconds, the brightness of the light reaches the minimum brightness and will not change. So cycle. Click touch and long press touch can be used at any time without interference or restrictions on each other’s functions.
3. The LED touch stepless dimming function without brightness memory is based on the LED touch stepless dimming function without brightness memory. When you click the touch to turn on and off the light, By making the light transition from a lower brightness to the initial brightness when the light is turned on slowly and smoothly, when the touch is turned off, the light is slowly and smoothly reduced from the current brightness until it is turned off, so as to achieve the visual buffer effect of slowly changing brightness and protect the eyes and vision effects. The LED touch stepless dimming function with brightness memory and fading in and out is based on the LED touch stepless dimming function without brightness memory and fading in and out, adding a brightness memory function. That is, when the AC220V power supply is not powered on, the brightness when you click and touch to turn off the light will be memorized, and the next time you click and touch to turn on the light, this brightness will be used as the initial brightness. In the case of AC220V power failure, the first click after power on is to touch ON.
