the TCD output will go LOW when the circuit is in the zero state and the CPD goes LOW

Since lithium batteries demand a special charging regime

with 7 considered to be neutral

3V power in to VCC) and the SDA and SCL pins will be at 3

Touch Keypad Module 4×1 OS25B10 Optocoupler isolated outputIntroduction : This Capacitive Touch Module uses the touch sensing IC TTP224 to add capacitive touch to your project . Just power with 2. 4 to 5. 5VDC and touch the pad to activate the sensor. These touch switches interface easily to any project with or without a microcontroller. When a capacitive load (such as a human hand) is in close proximity to the sense pad, the sensor detects the change in capacitance and activates the switch. Custom sense pads
