Interfacing 74HC595 Serial Shift Register with PIC Microcontroller

There are possibilities in embedded design where you do not have enough I/O pins available in your microcontroller. That can be due to any reason, may be your application needs multiple LEDs or you want to use multiple 7-segment displays, but you don’t have required I/O pins in your microcontroller. Here comes a perfect component, shift register. Shift register accepts serial data and give parallel output. ...

Timers of PIC microcontroller How to generate delay

USING TIMERS IN PIC18F452 MICROCONTROLLER:Timers and counters are important as timers can tell the time and count. Counting and timing allows for controlling the brightness of LEDs, controlling the angle of servo shafts and PWM signal generation etc.  All microcontrollers have clocks in them or they use the one that resides outside of a microcontroller. Microcontroller needs clock so our programs can be exe ...
