Dark-Detecting LED
Here’s a simple problem: “How do you make an LED turn on when it gets dark?” You might call it the “nightlight problem,” but the same sort of question comes up in a lot of familiar situations– emergency lights, street lights, silly computer keyboard backlights, and the list goes on.

Fading LEDs
Two strips of LEDs fading in a complementary manner 9V Battery-operated portable unit. This circuit operates two LED strips in pulsing mode, i.e. one LED strip goes from off state, lights up gradually, then dims gradually, etc. while the other LED strip does the contrary. Each strip can be made up from 2 to 5 LEDs at 9V supply.

Flashing LED with PIC12F629
This is the first example that you should to know how to set output pin. In this example, GPO is set as an output. LED1 will be turn-on when GP0 is set high and LED1 wiil be turn-off when GP0 is set low. This example use 4MHz internal clock.
