Review on π CenryKay 10PCS TTP223B Capacitive Digital Touch Sensor Button Module for Arduino by Joseph Lang
Works great in security and surveillance systems
I originally bought a red TTP223 which has no soldering compartment. Bought it instead and am very happy with it. Please note that the LED will not light up when touched.
- Jogging type: initial state is low level, when touched by hand, S outputs high level and the light is on; when the hand is released, it is low; Level
- There are other interesting options.
