LED Chaser
The project utilizes the Microchip PIC16F84 microcontroller, which is an 8-bit device featuring a 13-bit instruction set architecture. The microcontroller operates at a maximum clock speed of 20 MHz, making the choice of a 10 MHz resonator suitable for this application. The resonator provides the necessary clock signal for the microcontroller’s operation, and the built-in capacitors simplify the circuit design by eliminating the need for external components.
The circuit design likely includes essential connections such as power supply pins (Vdd and Vss), which should be connected to the appropriate voltage levels (typically 5V for the PIC16F84). The microcontroller’s GPIO (General Purpose Input/Output) pins can be configured for various functions, including digital input, output, or analog functions depending on the application requirements.
In addition to the resonator, bypass capacitors may be used across the power supply pins to filter out noise and stabilize the voltage supply. The schematic may also include pull-up or pull-down resistors on input pins, depending on the intended use of those pins.
The software for this project is written in Hi-Tech C, a popular compiler for PIC microcontrollers, which allows for efficient coding and easy debugging. The source code, with a ".c" extension, likely contains the main program loop, initialization code, and any interrupt service routines necessary for handling events such as button presses or sensor readings.
Overall, the design and implementation of this project demonstrate a fundamental understanding of microcontroller applications, including hardware interfacing and software development, which are critical skills in electronics engineering.This was my first sucessful project with a PIC chip.
