## Description

Touch dimmer module with PWM control for fine adjustment of light or other tasks in projects with Arduino and similar boards, also works independently, on/off with short touch and stepless adjustment with long touch, the sensor remains active even covered with acrylic or plastic up to 3 mm, 2.4-4.5 V power supply and dedicated outputs for LED.
Touch dimmer module with PWM function, compatible with Arduino and other development boards.
It can be used independently for light control or other projects requiring stepless PWM function.
It is possible to cover the sensor with acrylic or plastic material up to 3mm without affecting the touch function.
Functions: Short touch - ON OFF, Long touch - Stepless PWM Dimmer
Operating voltage: 2.4 - 4.5V
Connections:
VCC: Power supply voltage
GND: Ground
LED +: LED positive power supply
LED -: LED negative power supply
For controlling components operating at higher voltages, transistors can be used.
