Turning the Load On using External Control
The load can be turned on and off with an external
switch connected to pins 7 and 12 of the J1
connector.
Pin 7 of the J1 connector is internally pulled up to
5V with a 10kΩ resistor when the switch is open.
Thus when the switch is open, pin 7 is logically
high. When the switch is closed, pin 7 is pulled
down to the A COM ground level, making pin 7
logically low.
