I use LDR sensor for turn on LED when dark and I use PIR Sensor for check motion. If somebody pass the sensor then turn on more LED. And set all LED turn off when have no light. It like And Gate circuit. So, I try to use circuit like this.
I use LED 12V 1W 4 light so it is 4W. I test LED by connect to power supply it very bright. But when I connect LED to transistor 2N2222 in circuit it bright a little. how to make LED very bright ?
