Description

Circuit for a project with a single "momentary" capacitive touch sensor. No microcontroller is required here - just power with 1.8 to 5.5VDC and touch the pad to activate the sensor. When a capacitive load is detected (e.g. a person touches the sensor-pad area) the red LED lights up and the output pin goes high.
