SPICE simulated project of a PICDEM 2 PLUS demonstration board from Microchip. This board demonstrates the capabilities of the 18, 28 and 40 pin PIC 16 and PIC 18 microcontrollers. With the loaded program, four components are individually displayed on the LCD selecting the device mode by pressing RA4 button. It uses an A/D module to measure and display a voltage between 0V and 5V. A piezo buzzer can be turned on and its frequency and duty cycle can be changed when the buzzer is on, pressing the RB0 button. A digital serial thermal sensor TC74 measures the ambient temperature in celsius and display it on the LCD when the temperature mode is selected. At last, selecting clock mode, a real time clock will start from 00:00:00. RA4 button is pressed to set the digit to change and RB0 is used to increment hours or minutes.
