Step 2: Throwing molten lead
we will connect one wire directly between battery(-connector) and the small bit of PCB. Be sure this wire is soldered in the hole that is closest to the thicker black part of the circle drawn on the PCB. see photo.
Then, the other wire from the battery(-connector) to a switch, and finally a third wire from the switch to the other hole in the PCB.
This is a standard circuit that can switch on and of power to the LED strip.
IMPORTANT : BE SURE THE BLACK WIRE OF THE BATTERY CONNECTOR CONNECTS AS SHOWN IN PHOTO to the PCB.
it is important because otherwise you would in effect connect the battery to the LED strip the wrong way round, which might damage the LED strip.
