This code is for a simple RGB LED controller for 8 LEDs using a PIC16F628. The pattern is determined by the data in the EEPROM. Upon startup, the controller loads the data into RAM and starts up the sequence.

This code is for a simple RGB LED controller for 8 LEDs using a PIC16F628. It is controlled by sending 3 bytes to the internal USART for the red, green, and blue color channels.

Does anyone have a circuit and code for a simple countdown timer? It needs to count down from 2 hours 30 minutes and display on 3 or 4 7 segment displays.

This is a LED that does not really exist, it is in your imagination only. So how do you know wether this LED is on or off? By serial communication to the PC.

Use a switch to change the signal on a port, and turn the LED on and of based on that signal. A simple on off switch done the difficult way.

The evergreen in first microcontroller projects. Not much to say, the project is simple and straight forward.So to make it slightly more interesting two LEDs flash alternating.
