Resistor burned

Web\$\begingroup\$ @Alex, that resistor is extremely important and is almost certainly the reason your LEDs have been burning up. Also, note the power dissipation of the resistor. With a 15 Ohm resistor, the current will be 560mA. So the power dissipation is 0.56^2*15 … WebFirst Method Remove the external coating of the resistor body. Find the burnt section of the resistor and clean it. Grab a multimeter and measure the resistance from one resistor’s ends and the burnt section. Measure the resistance from the burnt resistance and the other end …
