The Proteus is a circuit designing software that contains a database of components, which we can use to build the circuit. This circuit is designed with the help of Proteus software. The Yellow LEDs is connected to the PORTB of the microcontroller. The reset circuit is interfaced at 1 pins of the microcontroller. The crystal is connected to the 13 and 14 pins of the microcontroller. The 5v DC supply is given to the 11 pin of the microcontroller which drives the circuit. If a microcontroller is reset for 3sec time delay, 10k resistor and 10uf capacitor are connected to the respective pins. At some times, the PIC microcontroller goes to block state or missing time calculation,at that time we need to reset the microcontroller. Two capacitors are connected to the crystal oscillator with range of 20pf to 40pf which is used to stabilize the clock signals. The PIC microcontroller transmit and receive the data with respect to clock pulses, the PIC microcontroller operates with 4MHz crystal frequency. The Crystal interfaced to the input pins of the microcontroller provides accurate clock signals at the crystal frequency. The microcontroller generates the output logic pulses so that the LED light is switched ON and OFF at certain intervals. The LED lights on the other hand, consume less energy and have longer life.īasic Idea of this Project Behind the Design: The LEDs flashlight uses a set of light emitting diodes, and these are advanced to the traditional incandescent lights which consumes more energy and have very less life time. As of now, consider the LEDs flash light system. Once you get the idea, this controller based project building becomes easy, so let us look at the basic steps to build a PIC microcontroller based project.īefore going to program the PIC microcontroller, first we have to select the right project that you are going program the microcontroller. Before going to build a PIC microcontroller project, we must become aware of developing a basic microcontroller (like 8051) based project. The PIC microcontrollers is programmed by the embedded C language or assembly language by using appropriate dedicated software. PIC Microcontroller Programming Procedure Even though there are many types of PIC microcontrollers, the best and basic microcontroller is PIC16f877a.

The PIC microcontroller programming can be carried out to perform the huge range of tasks. The PIC microcontrollers are found in most electronic devices such as alarm systems, traffic control systems and RFID based security systems, etc.

The PIC stands for “peripheral interface controller”, which contains memories, timers/counters, serial communication, interrupts and ADC converters built into a single integrated chip. The PIC is a family of the microcontroller, which is manufactured by the different companies such as NXP, microchip, etc.
