Electronic Brick Touch Pad Button Switch Sensor Module

Specification

• PCB size: 38.0mmX24.0mmX1.6mm
• Working voltage 3.3 or 5V DC
• Operating voltage 3.3 or 5V DC
• Compatible interfaces 2.54 3-pin interface and 4-pin Grove interface(1)
• Note 1: S for digital output port, N for not used pin, V and G for voltage at the common collector and ground respectively. When there is no operation, digital output is VDD; when the button is pressed down, the digital output is 0V.

Demo:

Connect S port of electronic brick of touch button switch to D2 port of Arduino board, and we will use the following program to read its digital value. When the digital value read is low level, LED lamp will be ON; when the digital value read is high level, LED lamp will be OFF.
