[EDIT FROM THE FUTURE : The problem was probably that the power supply was not capable of supplying the demand of the led strip]
I have created a basic (maybe too basic ???) circuit, using PIR sensor (HC-SR501), MOSFET (IRLB8721) and a 5 meters LED strip, which I have bought in EBAY, and I am not sure about it's specs exactly, I just know that it's 12vdc and that it was written on the package not to add more than 5 mts.
The idea of the circuit is to sense movement in the kitchen, and turn the LEDs on for a delay time, set in the PIR sensor.
What happens, is that when i connect the system to power (12vdc wall old charger 1A), the strip starts to blink non stop, in a frequency of twice a second. This is not what I meant. It should leave the lights on.
down there you can see the circuit.
Have I missed some important detail/component in the circuit ?
Might it be because there is demand for higher current than the wall charger can supply ?
I am a hobbyist, so please be simple with your answers.
Thank you
