Cabin Control with PIC18F2550 PIC18F2520 CCS C

Two interesting projects Inverer the-PIC and Terra PIC terra abviously with pets or aquarium cabinet temperature of the light feeding control enables Inveria the air control may be associated with exactly can not bring my project to publish reasons CCS prepared with source code and Orcad files that I did not understand my PIC Programming could be useful for dealing with our friends. Isis also came prepared with layers of simulation files in the library’s code a project that will benefit in every way

dsPIC30F3013 Meter Clock MCP6022 MCP4011 MCP9700A

The goal of this project was to build an unusual desk clock using a combination of old and new technologies. Time is displayed using vintage electro-mechanical meters, but the current time is calculated using a Microchip dsPIC processor. Further, a vintage quartz crystal plus a modern op-amp forms an oscillator that is the time base for the clock. All of the components are mounted in a glass-front box, so that both the old and new components are visible.

Three vintage meters are used to display the current time. A large meter indicates the hour from 1 to 12, while a smaller meter indicates minutes from 0 to 59. The seconds are not displayed by the clock; instead a small third meter is mounted upside-down so that its pointer can act as an imitation of a clock’s pendulum. The dsPIC30F3013 processor outputs signals to control a pair of MCP4011 digital potentiometers driving MCP6022 op-amps, which then drive the Hours and Minutes meters. In this way, the potentiometers and op-amps form simple D-to-A converters.
