Hi Marcus?
Would it work if I move the jumper on the blue pins from EN/BAT to the left GND/EN - You Reply:
EN by default is HIGH and I would like to turn it LOW … So I can control it with my ALARM camera ON/OFF - Topic: Guidance Needed for Controlling an Aquarium Mini Water Pump - Solar Controller 5V - Alarm OutYou Reply:
I´ve connected the 5V out to the + wire from the pump and the GRD to the - wire of the pump.
And trying to use the EN of the controller to ACTIVATE the PUMP with this setup
EN connected to ALARM OUT of the CAMERA
GRD connected to the COM of the CAMERA
Camera used a NO setup
All works good, except when the CAMERA loose power or reboot, since EN is by default HIGH the pump starts and only stops when camera is running again. I want to avoid this by setting EN by default to LOW is this possible? - Topic: Guidance Needed for Controlling an Aquarium Mini Water Pump - Solar Controller 5V - Alarm OutYou Reply:
Marcus,
The pump instead of USB could be connected to the RED jumper and add a MOSFET or RELAY and using ALARM OUT of the CAMERA to OPEN/CLOSE the RELAY and activate the PUMP?
