Newbie help please!
I have a GPS device that requires holding down a push button for about 4 seconds to turn on.
Ideally, I'd like to add a few non bulky components which will perform this action whenever power is connected to the device to automatically turn it on. The button cannot be held continuously as it changes modes if held for more than about 8 seconds.
If possible, I'd like to avoid a relay unless I can find a very small relay that will fit within the casing of the device.
The GPS device is 5V DC based and though I haven't measured it, I doubt the push button has more than a nominal voltage and current across it.
I've searched the forums and there are plenty of delay on and delay off relay circuits, but I've not found one that will do what I need.
Thanks.
