230 - Thử nghiệm mạch cảm biến TTP223 [ Testing Touch Sensor Module TTP223 On/Off mode]

In this clip we're testing the Touch sensor module TTP223. With Pad A and Pad B open, each time touching the sensor pad, the output will turn on and automatically. It will turn off once touching is released (Mode 1). Mode 2 is similar but in reverse mode with Pad A shorted. With Pad A open, and Pad B is shorted, the output is in Toggle mode (Mode 3). In this mode the output will stay on once we touch and release. The output will turn off if we re-touch the sensor pad again. Mode 4, Pad A and Pad B are shorted, result is similar to mode 3 but in reverse condition.
