assembly The project board was assembled from components with the instructions here. The PIC section was a well-planned project and a great introduction to the techniques, especially for a person with no soldering/capacitor-recognizing experience. It worked the first time, and who ever would have thought that alternating blinking lights would be so cool? A short (5 second) movie is available in divx format. |

playtime Blinking lights are important. To play with MPLAB and the other PIC goodies, I wrote a short program in C to blink the lights in Morse Code. A dot is 500 ms of green LED, a dash 750 ms of red. There is a 100 ms delay between each component of a letter, and a 200 ms delay between letters. A full space is 400 ms. The text can be changed by changing the string and its size, then reprogramming the PIC. It currently supports letters (case insensitive), numbers 0-9, period, comma, and '?'. A movie of almost one complete cycle (small flash card) is available in avi format. |
