A simple Blue LED driver Circuit
This is a simple Blue LED driver Circuit.It consists of the blue LED, a 1K ohm resistor, and a 9-V battery clip. LEDs have one lead longer than the other. This long lead must be connected to the (+) terminal of the 9-V battery using the clip leads.One lead of the clip should have the 1K ohm resistor soldered to it and the opposite end of the resistor soldered to the LED.
