How to install LED strip lights under counter Flexfire LEDs
Go to the LED Input Map page and assign the inputs associated with your PacDrive including the Input Codes for use in MAME. You should see the LED's light in realtime as you configure your ports. You should see the LED's light in realtime as you configure your ports.... the formula is: LED current in amps = 1.25 / R3 so for a current of 550mA, set R3 to 2.2 ohms you'll need a power resistor usually, R3 power in watts = 1.56 / R3 this circuit also has the drawback that the only way to use it with a micro-controller or PWM is to turn the entire thing on and off with a power FET. and the only way to change the LED brightness is to change R3, so refer to the

How To Power Start Leds
If you are connecting LEDs in series, simply add the forward voltages together before subtracting from the supply voltage. Things Needed The voltage of the battery to which you are connecting the LED The current to be passed through the LED The forward voltage of the LED (found on the LED's data sheet)
- LEDs – light-emitting diodes – have largely supplanted other sources of light in many applications. They are used in applications ranging from small on/off power indicators, to small and large alphanumeric displays, to screen backlighting, and even for area and street illumination.

- How is light produced in an LED? Light emitting diodes produce light by the movement of electrons between the two terminals of diode, which occur by a process called electroluminescence. When a light emitting diode is electrically connected, electrons start moving at the junction of the N-type and P-type semiconductors within the diode.
