Help! n00b with 4-pin, integral LED arcade button: wiring...
2016年4月20日 · LED: start with 1k resistor (current will be ca. (5V-1,6V)/1k = 3mA - this should already light the button LED. you can then lower it down to ca. 220 Ohm (5V-1,6V)/220 = ca. 14mA. The calculation is not exact as I don't know the exact value of the LED forward voltage. Based on long year experience you should not fry your LED with those values.
