Here a sample 3 watt led driver circuit diagram total 12 leds.
12 volt led driver circuit.
Simple basic led circuit.
1n4732a or 1n4733a any lower and q2 won t be able to turn all the way on any higher and it won t work with most microcontrollers.
12 volt basic led circuit with 560 ohms resistor.
Use a 4 7 or 5 1 volt zener diode such as.
