Have bought a ULN2803A darlington array and am using it for external LED's.
They work fine but they are always on. Is there a way to have TX switch controll all LEDs such that I can switch them off during the day.
I fiddled around with pin A9 for camera shutter and got that to work on a camera shutter switch set as relay but since its a shutter functionality, it comes on and switches off after some milliseconds. Also with the camera shutter approach I lose all indications I would get if connected to the NAV lights pins.
I am contemplating putting a manual switch on the quad on the +ve wiring for all leds.
Is that the only way?
