Hi i am trying to practise with LEDS on a "prototype" copper track board
i have a simple resistor on row one of 560 omh 1/4 watt
and a white LED , which has the specs of
LED / Lamp Size:3mm;
LED Colour:White;
Viewing Angle:30°;
Max Voltage Vf:4V;
Forward Current:20mA;
Opto Case Style:Radial;
Case Style:Radial;
Current If @ Vf:20mA;
MCD @ 25ma: 20000
Now when power is applied the LED is flashing at a slow rate , simular to a car indicator would blink
